Descriptions of new activities


Satellite sector market evolutionScope & Objectives• The present activity aims to provide a detailed qualitative and quantitative analysis of

the economic market conditions and their impact on satellite sector covering all actors –satellite manufacturers, satellite operators, ground segment, satellite service providers and application providers

• To address evolutionary scenarios within a study period of up to 10 years, the scenarios shall be substantiated by macroeconomics analysis using System Dymanic modeling and further validated by experts group (composed by sociologists, economists, technologists and satellite sector stakeholders with the participation of ESA).

• By developing a System Dynamic model, the findings can be verified and constantly monitored. This would give a tool which can be used to make market predictions not only based on figures from the past, but based on forecasts into the future.

• Main objectives cover the analysis of the :• Terrestrial telecom market place looking forward (i.e. 10 years) including investigation of

changes• Monitoring systematically users behavior and analysis of the end-to-end needs (incl. effect

of pricing policies)• End user devices evolution (i.e. convergence into IP)• Value chain evolutions (mergers & acquisitions)• Introduction of technological innovations and disruptive technologies• The media and network convergence• Impact of social/economic events, governmental intervention (i.e. climate change, specific

interventions & protectionism, regional policies etc)

• Duration: 24 months


Satcom systems green technology footprint

Background• The topic of eco-design applied to space systems has been the topic of a number of GSP studies

(for example EcoSAT, ‘Environmental sustainability of Space Activities’) target the overall space industry to measure its current impact on the environment (i.e. use of material, industrial processes etc), and investigate the current/up coming legislation on the production facilities.

• The issue of green technology footprint is subject also of several studies conducted by national authorities (i.e. OFCOM), industry and associations

• EC prepares a specific action on the promotion of green footprint technology.

Scope• The proposed activity tackles the issue of social impact of satcom considered as green

technology. In other words, the activity aims to build the case for satcom services as green technology. In order to fulfill this objective, the study must consider use cases with well weighted business models and associated satcom infrastructure for the services deployment. Typical cases seem to be the broadcast/broadband services.

• The study activity shall liaise with the above mentioned GSP studies for harmonization purposes. Another liaison is with the ARTES1 ITT under preparation on ‘METHODS FOR ASSESSING PUBLIC VALUE OF SATCOM IN A SPECTRUM TRADING ENVIRONMENT’ where the ‘green technology’ footprint of satcom is considered as criteria for assessing public value.

– Duration: 6 months


Study of a strategy for introducing innovation in satcom commercial scenarios

and experimental payloads definition/1

Background• ESA had used different PPP approaches as is evident from the latest experience with

the commercial Satcom operators (Eutelsat: Skyplex, Hispasat: Amheris, Inmarsat: Alphasat and TDP#, Avanti: Hylas, Hispasat: Small Geo mission and the newly envisaged EDRS). This ESA experience has clearly demonstrated that it is possible for commercial satellite operators to preserve their commercial priorities and still manage to achieve flight heritage for newly developed technology that might eventually increase the competitiveness of European industry.

RequirementsBuilding upon the Agency’s last PPP experiences, the proposed study shall aim to analyze

– PPP schemes in cases where national agencies are willing to host within their own national satellite programmes ESA payloads or vice versa,

– the case of large scale PPP schemes involving a large number of private (commercial) partners e.g. similar to Alphasat,

– the case of PPPs for the development of new dedicated satellite(s) where specific SLA agreements are needed to be defined for future ground user segment and services development,

– How to encompass the results of the working Group on PPPs with launchers.




Scope• The activity has two-fold aims, to:

– Systematize essentially the approach of partnerships procurements for new systems and piggy back payloads so as to enable flight heritage opportunities for newly developed system/technology or newly envisaged services (high market risks) through the exploitation of several launch opportunities that exist yearly from the launch of commercial Satcom operators.

• The approach is deemed to reflect the operators’ commercial constrains and their assessment of risk retirement with respect to innovation. Innovative concepts shall be investigated based on partnership with operators, where operators might provide:

• low cost piggy-back opportunity on their commercial satellites –with very limited incremental cost for operators but high saving for ESA;

• cheaper operation of ESA developed payloads and related services. • The overall framework for the above scenarios considering in particular the liability

aspects and the overall mechanism of implementation shall be assessed.

– As a special use case of the above approach, the activity shall define, analyse and preliminary design two (small and medium scale) experimental technological payloads for in orbit demonstration of advanced technologies on communication satellites. Possible flight opportunity options will be proposed and analyzed, and relevant constraints and design guidelines will be derived. Candidate technologies will be short-listed based on cost/risk/benefit analyses and required development actions will be defined.




Objectives (part 2)• Considering the financial effort needed to support in-orbit demonstration

activities it is mandatory to analyse thoroughly the various technological options and to prioritize the activities to be undertaken.

• In this respect the present activity will tackle the following aspects:– Analysis of viable options for satellite communication technology in-orbit-

demonstration– Definition of two possible scenarios and relevant requirements and constraints

for two classes of experimental technological payloads– small scale (single by-passable transponder option). This payload can be used to demonstrate

new technologies (i.e. new TWTAs, filters, converters, LNAs…) – medium scale (self contained payload fulfilling a scaled down mission). As possible examples,

scaled down versions of payloads using active/semi active antennas, broadband digital BFNsusing advanced digital technologies, optical frequency conversions…)

– Definition of key technological elements and cost/risk/benefit analysis at element/subsystem/ payload level.



Approaching the Terabit/s Satellite: A system study

• The 2nd generation Ka-band satellites (Wildblue-II, Viasat-I, Ka-sat) is achieving the economy of scale thanks to small satellite beams with high frequency reuse and ACM (100 Gbps around 2010). But the challenge remains as IP traffic will nearly double every two years (according to Cisco forecast). In order to keep and expand satellite market share in the interactive broadband arena, satellite capacity shall be drastically enhanced in the coming years (Terabit/s satellites).

• The next generation Terabit broadband satellite systems (2017-2020 timeframe) will have to cope with the following challenges:

– users will require higher data rates and volumes for the same price, traffic will continue to develop in a very non uniform way, need to support both interactive and broadcast services (multi-mission satellites), and not all regions of the world can commercially exploit very high frequency bands because of too heavy fading (need for broadband solutions for rainy regions).

SCOPE• The study shall address the next generation broadband satellites timeframe (2017-2020). Different

system solutions covering system, space, ground and user segments shall be derived. The trade-off between different options shall consider technological readiness and costs.

• The expected outcomes are:– Service demands for next generation broadband satellite systems;– Identification of satellite system architectures together with main system performances and budgets;– Identification of technology gaps and technological roadmaps;– System and service cost analysis;– This activity mainly targets BSS operators and industrial teams.

– Duration : 15 months


Next Generation Mobile Satellite Systems/1Background• Despite the very modest commercial success of the satellite mobile networks based on

constellations deployed in the ‘90s, global and regional satellite mobile networks are still representing a commercial reality and generating revenues. The last generation Inmarsat BGAN demonstrates that satellite networks are also moving from 2G to 3G. Furthermore, another opportunity for the satellite appears in the rollout of hybrid mobile networks in USA and Europe.

• In this context, the activity “Study of Satellite role in 4G networks already identified several areas where extra effort is required regarding payload architecture and integration with terrestrial networks.

Scope• The study shall identify efficient satellite centred system architectures providing mobile satellite

services to different mobile and nomadic terminals. It shall consider service demands for next generation MSS and shall analyse the possible technological solutions. The study shall look at the most adequate frequency allocations for the provision of the identified services. The architectural analysis shall be forward looking (2020 timeframe) and shall consider ground and space segment, terminal constraints and regulatory and standardisation aspects. The trade-off analysis shall consider technological readiness and costs. The expected outcomes are:

– Identification of satellite system architectures– Assessment of new payload architectural concepts enabled by the introduction of new technologies (e.g. GaN,

large reflectors…)– Identification of technology gaps and Technological roadmaps– This activity targets MSS operators and satellite sub-systems equipment manufacturers.– The successors of this activity will be proof-of-concept demonstrators and payload/antenna technology

activities.


• This activity will focus therefore on the following aspects:– Analysis and trade-off of advanced payload architectures e.g.

• New digital processor architectures• Advanced pre & post processor analogue chains with possible integration of ADC and

DACs together with frequency conversion on the same mixed analogue/digital chip• Advanced GaN technology (e.g. flexible GaN SSPAs etc)• High number of spot beams (integrated RF front ends supporting large number of

beams)• Optical signal and LO distributions• Increased reflector size and number of beams and frequency reuse

– Enhanced waveform analysis• Trade-off of the possible solutions analysed in the 4G study (LTE, WiMax) together with

DVB-SH and considering also the DVB-S2/RCS_NG– Detailed analysis of the integration with terrestrial networks

• Networking aspects affected by mobility in hybrid scenarios shall be analysed: impact on handover latency and efficient use of satellite bandwidth.

– Allocations below and above 5GHz shall be explored and the most suitable allocations shall be selected. In this sense, technology allowing for low cost mobile terminal in Ku/Ka band shall also be analysed.

Future Satellite Systems supporting UAS C2 : a pre-WRC-12 study

• The unmanned aviation community is currently supporting the bid at WRC-2012 for frequencies dedicated to command and control of UAS’s. It is believed that this is a key enabler for UAV integration in civilian airspaces.

• A recent CEPT proposal for WRC-2011 concluded that a total of 47 MHz will be required for the UAS command and control via satellite by 2030 in an AMS(R)S band (at least satellite/UAS link). Once this frequency band is made available from WRC-011 a new niche market could well develop for safety satcom services in e.g. C-band (5030-5090 MHz).

Scope• The overall objective of the activity is to formulate some initial system concepts for a new civil aviation satellite communications

system providing beyond-line-of-sight (BLOS) command and control communications dedicated to safe-and-seamless insertion of UAS in non –aggregated airspaces. (C2 includes Command & Control, ATC relay and Sense & Avoid communications).

• This would serve the ongoing standards development in EDA, EASA, Eurocontrol, EuroCae, RTCA and FAA related to UAS insertion and would further assess satcom capabilities on this new market. This would also serve CEPT and ITU-R negotiations to provision new satcom frequency bands for that purpose from WRC-2011 which is a key recognised barrier to UAS insertion

• The activity shall build upon related internal activities (GSP, Iris, IAP and ARTES 1 -ATM), external activities (EDA studies) and perform a detailed Phase 0 study on a satellite communication system supporting UAS C2 in WRC-011 candidate bands.

Objectives• provide a short overview of relevant issues already studied in previous ESA and external studies • identify user and civil aviations requirements of UAS insertion in non segregated airspaces (e.g. SWAP, capacity, availability…)• align with WRC-11 schedule and frequency band solutions as well as ICAO, RTCA and EuroCae standard developments• investigate various satellite system solutions and architectures for UAS C2,including sharing/compatibility issues in eg MLS band • investigate the candidate waveforms and associated security aspects• develop deployment scenarios for an initial capability for C2 of UAS,• present the business case and the viability, including non-economic factors such a legal, political issues,• investigate the safety, latency, security and certification issues,• investigate interaction and interoperability with line-of-sight (LOS) communications• involve the major stakeholders (EUROCONTROL, EUROCAE, EASA, EDA, national air navigation service providers) to discuss

viability and policy issues,• present such satellite system solutions actively to the UAS community,• lay out the required technology development roadmap for space, ground and user-segment,• suggest standardisation/certification paths.

– Duration: 12 Months


BACKUP SLIDES ON THE ACTIVITY


UAS activities in ESA - DRAFT


Differences with Integrated Application ITT (in cooperation with EDA)

•The IAP(ARTES20) activity will address UAS services taking into account currently availablespace, ground and airborne infrastructure. The ARTES1 activity will explore a novel system, that will need new (piggy-back) space and ground infrastructure, and possibly new user segment. The scope is therefore fundamentally different.

•The IAP(ARTES20) activity will look at the business case for a complete demonstration and future service, again using existing infrastructure. The ARTES1 activity however will provide a business case, but taking into account dedicated (piggy-back) space segment.

•The IAP(ARTES20) activity will specifically look at how UAS can be integrated into civilian airspace supported by satellite communications. The emphasis is on the support to rule-makers means of demonstration, and to pilot the services that could be developed if such integration is achieved. None of this is part of proposed ARTES1 activity.

•The ARTES1 activity will take into account current ideas and positions as being prepared for WRC-2011/12 for what concerns new frequency bands for UAS command and control. In addition, the ARTES1 activity will have the opportunity to interface to emerging SESAR developments in the area of UAS. This is not within the scope of the IAP(ARTES20) activity.


The usage of CCSDS & IP protocols to UAV C2 communications /1

Background• Most current UAV applications are military and are based on military communications

standards like STANAG 7085. Those standards are by definition not publicly available and, therefore, cannot be used for civilian UAV applications. They also do not cover satellite links.

• The need for a (Command & Control) C2 standard has been identified as an enabler for the development of civilian UAV market[1] . A future C2 link implementation will need to be certified by Civilian Authorities and as such a certification process will benefit if started from an established standard. While an UAV is not a spacecraft, there are many common aspects in their control and monitoring but also expected differences.

• The CCSDS has standardized various families of protocols covering from physical up to application layers. Some of those protocols offer the capability to accommodate varied types of traffic (e.g., tele-command, telemetry, voice, and video). Similarly, IP-over-satellite protocols have been standardized for various satcom applications.

• The CCSDS has standardized various families of protocols covering from physical up to application layers. Some of those protocols offer the capability to accommodate varied types of traffic (e.g. tele-command, telemetry, voice, and video).

• The potential for reusability of the CCSDS and IP protocols is expected to be greater for the data domain. RF and modulation standards will most likely need adaptation. Complementary aspects of security, essential for UAV application, are also being currently standardized within CCSDS and IP on the data domain (authentication and encryption).

Scope & Objectives• The study aims to analyze the feasibility of using CCSDS and IP protocols

in particular at the data level, on UAV command and control communications and determine modifications/adaptations that those standards could require to fulfill the civilian UAV applications.

• In particular the study shall also develop a software protocol emulator to realistically emulate channel and scenario conditions.

Comments• The study relates to other UAS activities in ESA as follows:

– IAP(ARTES 20) studies will establish requirements for C2 Civilian applications but they do not investigate CCSDS.

– The UAS GSP studies gives an indication of the expected UAS links that need to be supported and the limitations regarding data-link implementations on-board.

– The proposed study is relatively independent of a proposed ARTES 1 UAV C2 system study, assuming that a proposed C2 data link will need to work with various (transparent) satellite payloads.

• Duration: 12 Months

Seamless Content Delivery over Integrated Satellite and terrestrial networks/1

Background• Network convergence in fixed/mobile/broadcasting environments is an evolutionary process and

the seamless content delivery over these converged and integrated networks remains an interesting developing topic.

• Networked future is not envisaged to be simply a faster way to go online but it is expected to fundamentally change the way users use the networks and their ability to produce and deliver multimedia content.

• While this vision for the future is shared by an increasing number of telecom actors incl. in the satellite domain, the actual implementation models of converged environments and the seamless integration of satellite and terrestrial links is still an open issue.

• The activity in preparation ‘Satellite centered service platform in converged mobile/fixed/ broadcasting environments’ identifies system use cases –defining the role of different actors, critical problems and potential solutions for different scenarios of integration of satellite links and alternative terrestrial technologies. Starting points are examples of use cases dealing with combinations of DVB-S2, DVB-SH, -nGH or -RCS and 3G links. User requirements, reference network architectures are being studied and solutions permitting different levels of integration such as deployment of local caches and adaptation engines at terminals side and the integration of more advanced network awareness modules at core network are investigated.

Scope• The present activity shall build upon the results of the previous mentioned activity to investigate

seamless content delivery using combinations of Scalable Video Coding (SVC), MDC (Multi-Description Coding) and Multi-View Coding (MVC) over these combined access networks. P2P logical overlays topologies shall be examined. The study aims to assess multi-target integrated satellite/ terrestrial networks capable of addressing heterogeneous user terminals and displays’spatial resolutions.


Seamless Content Delivery over Integrated Satellite and terrestrial networks/2

• In such evolutionary scenarios where different routes are included in the final content delivery including satellite broadcast/multicast links and terrestrial unicast ones, the applications’ scalability based on combined SVC, MDC and MVC is the logical partner of the setup.

• All these coding schemes are been standardized by the MPEG/ISO community; SVC is ISO/IEC AVC/MPEG4-part 10; MVC of ISO/IEC MPEG06 and the MDC is subject to standardization under progress.

• Seamless content delivery to heterogeneous terminals necessitates different levels of network scalability, mobility support, perceived QoS (PQoS), and error resilient techniques. All these system parameters combine differently with the level of video scalability provisioned by SVC, MDC and MVC.

Scope & Objectives• The study shall assess system cases of integrated DVB-SH (-nGH)/DVB-RCS and 3G links or

other alternative terrestrial links such as WiMax and assess their end-to-end system performance using appropriate simulator where realistic satellite links characteristics are modeled. Meaningful network and application PQoS shall be provided in terms of the average satellite bandwidth available in conjunction to the specific service and applications delay profiles and other system parameters as appropriate.

• Expected results include:– Proposals for future developments necessary for converged terminals and core network elements,– Implementation guidelines for the different studied use cases,– Dissemination appropriately to standardization committees such as DVB-AVC, EBU and ETSI.



New approaches to realizing satcom network management architectures/1

• Business applications and other software supporting the satcom value chain are very often built around bespoke or legacy systems. These systems tend to lock satellite and satcom operators into single vendor solutions for subsequent maintenance and upgrade.

• These systems although satisfactory are not very flexible; they do not guarantee multi-service, multi-standard and multi vendor operations, missing easy integration and data exchange with systems used in the terrestrial word as well as disabling any mode for interoperability and convergence; issues of extreme importance for emerging satcom business models.

• These systems do not readily permit reuse of new (software) tools and techniques; including COTS low cost solutions used in the terrestrial world. That leaves optimisation resources unused to improve business effectiveness for satcom operators and service providers (e.g. automation).

• Importantly the existing tools do not exploit developments in open standards or open interfaces (“plug and play”) and service or model driven architectures prevalent in ICT today.

• To accelerate the adoption of satellite access networks within telecom global networks, network management processes and interfaces between telecom and satellite operators would need to be simplified and standardised. Currently, network management issues are the cause of various objections raised against the introduction of a satellite platform in a global network (i.e. Public/private addresses issue, quality of service and billing issues, CPE installation and management issues).


New approaches to realizing satcom network management architectures/2

Scope & objectives• The activity aims to identify and then analyze the feasibility of a set of “standardized”

satcom network management services to allow ground segment components to be simply integrated (“plug and play”) into the resulting architecture.

• The activity shall review the problems caused by the introduction of a satellite platform within a business network (Internet/Intranet/Extranet) from the network management point of view. It shall provide recommendations for satellite operators for establishing a standard framework of business process and application landscape as well as interfaces that also would support the easy integration of satellite access networks in global networks.

• This approach would improve the overall operational efficiency of Satcom Operators and reduce the cost of ground segment components.

• The approach is essentially enabling in that the solution would be “open” to all.• By driving this activity it would give Europe the opportunity to leapfrog US

competitors. It is therefore strategic.

• Initially the study shall recollect requirements from satcom operators and service providers

• Evolutionary scenarios shall be discussed within a working experts’ group (composed by satcom operators, service providers, satellite ground segment manufacturers with the participation of ESA).



Framework support to standardisation:Efficient networking and MAC techniques in next

generation interactive broadband satellite networks/1Background• Interactive broadband satellite networks targeting consumer and business applications have to face

many stringent requirements and constraints to be competitive wrt. terrestrial networks. The major one is to be able to deliver to end-users the same experience as terrestrial alternatives at an affordable cost. Broadband satellite networks also have to be capable of a seamless integration with the Internet and to offer to operators the possibility to be managed as any other access networks. Furthermore, for DVB-RCS NG systems, interoperability between multi-vendor sub-systems is a major requirement.

Scope• The activity shall study efficient networking and MAC techniques in interactive broadband satellite

systems (DVB-RCS NG, VSAT, mesh …) to cope with these requirements.• Among the upper layer techniques which may greatly participate in the performance optimisation,

the study will address header compression which has been little studied by the space community. The efficient integration and use of random access techniques in systems also implementing DAMA, for the improvement of the offered QoS, will be analysed too. Regarding the integration with terrestrial infrastructures, the study will analyse e.g. techniques enabling the satellite system to seamlessly extend terrestrial Virtual Private Networks based on commonly used technologies, e.g., VLAN 802.1 Q or MPLS, as well as the required adaptations for the migration towards IPv6. Additionally, the integration of OSS solutions commonly used by ISPs/Telcos for alternative access networks will be considered. Key interoperability issues at upper layers for DVB-RCS NG systems will at last be analysed.

• The activity will have to identify appropriate and efficient techniques and solutions, and to validate them through UML-like models.


• This activity will focus on the following aspects:– To improve the performances of interactive broadband satellite

networks (DVB-RCS NG, VSAT, mesh),– to allow their integration within the Internet in an efficient and

competitive manner wrt. terrestrial networks,– to cope with interoperability issues between multi-vendor sub-systems

in case of DVB-RCS NG systems.– To simulate and validate these techniques through UML like models– To define generic recommendations on the use and implementation of

optimised and efficient upper layer techniques for interactive broadband satellite networks. These generic recommendations will be made public and available by ESA to interactive broadband satellite networks stake-holders .

– To provide contributions to the DVB-RCS group defining a full end-to-end solution for DVB-RCS NG.


Framework support to standardisation:Efficient networking and MAC techniques in next

generation interactive broadband satellite networks/2


Framework support to standardization: Integration of Satcom Access Networks in IMS Core networks

Background• The general trend in telecommunications is the move away from "vertical" architectures relying on

access specific networks towards converged "horizontal" architectures where core networks and service architectures are shared among several access technologies.

• Telecom operators are favoring the IMS ("IP Multimedia Subsystem") as the architectural framework of choice for the next generation of telecommunications networks, where a single IP backbone will be used in conjunction of different access networks. The IMS is expected to offer substantial cost savings and enable the convergence of services in fixed and mobile networks. As satellite networks are interesting candidates for integration in next generation networks, especially as access networks, the issue of their seamless integration with IMS is a strategic one.

• Currently two parallel ARTES-5 activities "IMS Satcom Integration" are being finalized. These two activities, run respectively by consortia led by Siemens (A) and TNO (NL), have addressed in detail, by means of analysis as well as simulation, the integration scenarios between satellite broadband access networks (DVR-RCS) and the IMS. They have identified a number of challenges for IMS/Satcom integration, and critical areas to be addressed by standardization in order to guarantee integration.

Scope & Objectives• The activity aims to consolidate the findings of the two ARTES-5 studies, select the suggestions

for areas to be standardized (e.g. billing, admission control) and map them to relevant standardization bodies. The team running the activity will then actively participate in standardization by proposing activities to these standards bodies, and according to their feedback by allocating the effort to specific working groups in those standards bodies which will be found most suitable - both from their confirmed interest as well as from a timeliness point of view (i.e. compatibility with the project timescale).
