EP FOR ON-STATION USE: EUTELSAT 16C AND KA-SAT

EUTELSAT 16C (SESAT-1)

SESAT-1 (Siberian European SATellite) was manufactured by Russian ISS-Reshetnev

(former NPO-PM) and derived from Express family. Payload manufactured by TAS (former Alcatel)

Launched in April 2000 on Proton K-BlockDM direct to GEO

Electric Propulsion System used for orbital acquisition, NSSK, EWSK and relocation.

Designed for a nominal lifetime of 10 years,

after 17 years EUTELSAT 16 C is still working properly as expected

To be deorbited next January 2018

6 EPIC Workshop – October 24-25, 2017 - Madrid

Ka-Sat

KA-SAT was manufactured by Airbus D&S based on Eurostar 3000 platform

Launched in December 2010 on Proton Breeze M and released in GTO

Electric Propulsion System used for NSSK, orbit inclination and eccentricity control

Designed for a nominal lifetime of 15 years, after 7 years Ka-Sat is performing fully according to

specifications

What makes Electric Propulsion proposition attractive for Electric Orbit Raising (EOR)?

EP ATTRACTIVE

FOR EOR!

In the last decades, the installed power on Telecom GEO platform has been continuously growing.

EP Value for EOR: Further Reduction of the Cost per Transponder On Orbit!

As consequence, new design of telecom platforms, with Electric Propulsion with primary functions are now proposed by all major spacecraft manufacturers

New launch service providers have renewed competition in the launcher market driving down the launch costs

Necessary conditions created for EP to become an attractive value proposition also for EOR

SESAT/EUTELSAT 16C (2000) ISS-RESHETNEV

Electric propulsion for station-keeping, direct geo insertion

Reduced cost per bit

KA-SAT (2010) AIRBUS DS

Electric propulsion for station-keeping to maximize the throughput

Reduced cost per bit

EUTELSAT 115 WEST B (2015) BOEING

First full EOR for a commercial satellite

Launched as a pair on Falcon 9, very competitive launch cost

EUTELSAT 117 WEST B (2016) BOEING

Second eutelsat full EOR

Launched as a pair on Falcon 9, very competitive launch cost

EUTELSAT 172B (2017) AIRBUS DS

First European full EOR commercial satellite

Compatible with Ariane 5 low position, reducing launch

cost by ~40% vs. Upper position

AFRICAN BROADBAND SATELLITE (2019) THALES ALENIA SPACE

First full eor Spacebus Neo spacecraft

Higher throughput and compatible with most competitive launch

solutions

EUTELSAT 7C (H2 2018) SPACE SYSTEMS LORAL

First full eor Space Systems Loral spacecraft

Compatible with Ariane 5 low position, reducing launch

cost by ~40% vs. Upper position

EUTELSAT 172B HAS RECENTLY REACHED THE GEO ARC!

9 EPIC Workshop – October 24-25, 2017 – Madrid

Manufactured by Airbus D&S, derived from E3000 L platform

High-capacity satellite to provide continuity and expansion in Asia Pacific region with 36 Ku band, 14 C band and 11 HTS Ku-band spotbeams

Launched on 1st June 2017 on Ariane 5 low position and separated in a GTO orbit (launch mass = 3550 kg)

To be positioned at 172° East for a design lifetime of 15+ years

EOR cruise phase started on June 8th and was successfully completed on October 11th after about 4 months

So far the fastest full EOR for a GEO Telecom platform

In-Space Servicing

Refuelling for lifetime extension

Reorbiting or spacecraft rescue

Orbital slot/orbit change

In-orbit assembly/repair

LEO Constellations

Increase of lifetime

Reduction of wet mass

Challenge on EP cost reduction
