1. SCOPE

This document establishes the technical requirements for the design and manufacturing of two satellites mock-ups,for Herschel and Planck satellites, and for the verification of the RF patterns of the wide coverage TTC antennas to bemounted on-board.

Alcatel is the Prime for both satellites, whereas ALENIA Spazio is the Service Module (SVM) provider, which includesall antennas as part of the TTC subsystem.

These tests on RF-mock-up take part of the overall RF performance verification at both SVM and satellite levels.The outcomes of this test campaign will be reviewed at the system Qualification review (QR), planned in December2004 (tbc).

This verification is split as follows :1) Analysis by GTD on a software with a modelling of the Satellite Structure and of the antennas patterns

interferences.2) RF patterns measurement on Satellites mock-ups with the flight antennas3) Verification of peak gain and of gain measurement

The same kind of X-band frequency antennas will be used on both satellites, low gain antennas (LGA); they will befurnished by the Customer as CFEs, to be returned at the end of RF tests. Note that flight hardware will be used.

A complete measurement of overall RF patterns, shall be performed on both satellites mock-ups.

The materials used to build these mock-ups shall obviously be RF representative of those actually used on theSatellites.The Contractor shall, on top of the mock-ups design and manufacturing, provide the adequate test facilities toperform the required RF patterns measurements, in X-band frequency.

The reason for using mock-ups instead of using the actual satellites is to save time on the schedule by anticipatingthis task but also because of the easiness of handling mock-ups in place of the actual satellites.

The RF mock-ups specified in this document shall be designed to withstand a possible activity outdoor or in ananechoid chamber with all associated cleanliness constraints.It is not needed, unless specified otherwise, to deliver these mock-ups but they will in any case become the Customerproperty.

Applicable requirements to the RF mock-up and tests are identified by RFMCK_T# followed by a number

2. SYSTEM DESCRIPTION AND DEFINITION

2.1 SYSTEM DESCRIPTION

HERSCHEL and Planck are two scientific spacecrafts. The two programmes are developed by the European SpaceAgency under the Science Programme Committee approval.

Herschel MissionHerschel is a Far Infra-Red and Submillimeter Telescope (formerly called Far Infrared and Submillimetre Telescope orFIRST).Its observation domain opens a window over the thermal emission of very cold objects such as interstellar orcircumstellar dust and gas clouds, and over the brightest molecular and atomic emission bands of gas at « low »temperature (that is lower than a few hundreds of Kelvin).

Planck MissionPlanck is a spinning spacecraft carrying a millimeter and sub-millimeter telescope. It is named after the physicist MaxPlanck (1858-1947). The spacecraft is dedicated to the measure of the fine cosmic background temperaturefluctuation.

Mission commonalitiesThe two spacecrafts are developed as a single project. They share indeed a large number of characteristics.The two core SVM platforms are similar.

2.3 DEFINITIONs

2.3.1 General

2.3.1.1 Mission phases

For each satellite the Mission is split in a Launch phase, a Transfer phase and then, in an alternate way, a Scienceobservation mode (only the TC Receivers are ON) and a Data Transmission mode. As well an Emergency / Survivalmode is foreseen.During all mission phases the Spacecraft shall be able to receive telecommands and transmithousekeeping data in any attitude and orbit position , i.e. omni-directional coverage shallbe provided.

2.3.1.2 Satellites orbit and attitude

Herschel and Planck operate at the « L2 » Lagrange point of the Earth-Moon and Sun system. This point lays about1.5 million Km out in the Sun to Earth alignment. The spacecrafts indeed oscillate around the L2 ideal position with aLissajou orbit.They are permanently within a few degree of the Earth and Sun axis, and are so permanently lighted (no eclipse).Herschel is a three axis stabilised satellite, with the +Z axis permanently pointed toward the Sun.Planck is a spinned satellite with the –X axis (Spin axis actually) permanently pointed toward the Sun.

2.3.2 TTC coverage and Antennas types

The targetted TTC omni coverage is implemented by a set of LGA on each satellite. Each satellite having a differentorbit and attitude with respect to the Sun and the Earth, the number of antennas and locations is slightly different onPlanck and Herschel.

The purpose of the low gain antennas (LGA) is to provide an omnidirectionnal coverage on both Satellites, whateverthe Satellite attitude is, in all phases of the mission (Launch, Transfer, Operational or Survival Orbit).The individual pattern of this antenna is of hemispherical type (see section §2.4.2.1).Planck : three LGAs are foreseen, one main (-X) and two redundant antennas (+/-Z). If the Satellite Attitude isnominal, then the main LGA only is used. During Launch, Transfer or Survival modes, also the redundant Antennasmight also be used. The redundant LGAs on Planck actually have their patterns significantly impacted by the SVMstructure, the PLM structure and the Solar Array panel.For that reason the system GTD analysis has lead to an optimised inclination of these LGAs with respect to the SVMpanels :

On each Satellite, the LGA can be equally used for TC receive and TM transmit function. The LGA 1 isconsidered as the nominal LGA used in TM/TC under nominal attitude of the Satellite. LGA 2 (and LGA 3on Planck) are used in case of attitude loss or any critical orientation of the spacecraft.Hence, the targetted omni-directionnal coverage is obtained by conjonction of all LGAs on each Satellite.

Actually, the measurement main objective on the RF Mock-up is to perform a simultaneous measurement of PlanckLGA2 and LGA3 antennas, coupled with a representative set of waveguides and coupler (CFE as per SOW).

2.5 RF MOCK UP REQUIREMENTS

Mock-up RF interfaces[RFMCK_T#1] The implementation on the mock-up shall use the same interfaces as those used on the spacecraft. Allconnections shall be made with standard wave guide WR112 flange.[RFMCK_T#2]On Planck Mock-up, a representative flight set of waveguides from LGA2, LGA3 and the ending coupler(see figures 2.3.3 and 2.4.6) will be provided as CFE and shall be used by the Contractor in order to accesssimultaneously both LGA2 and LGA3.

Mock-up Antennas I/F brackets[RFMCK_T#3]Dedicated support brackets shall be designed and manufactured or procured to be compliantwith flight HW in order to accommodate the antennas in the required positionaccording to SVM configuration (RD 1).

Mock-up representativity[RFMCK_T#4]For both mock-ups, the external shape shall be fully representative to the actual satellites to allows a validmeasurement of the RF patterns degradation due to reflections and diffraction on the structure of the satellite. Thispoint is of the highest importance for Planck in particular. Anyway in some areas the mock-up can be simplified w.r.t.the actual satellite. The Contractor is invited to make various trade-offs, in that respect, and the final mock-up levelof details and representativity will be discussed and agreed with the Customer.

DesignCATIA file of both satellites will be provided by the Customer, and will have to be used by the Contractor. Potentialsimplification of the mock-up design/shape compared to the actual satellites design will be subject to the Customerapproval. Final agreement shall be reached at the MRR.

Mock up design accuracy[RFMCK_T#5]For large items like SVM structure, Solar array panel, Telescopes, the required accuracy in the manufacturing w.r.t.the actual Satellite dimensions is of 1cm worst case.For small items, like ACMS (Attitude Control and Measurement System) and RCS (Reaction Control Subsystem) dummies locatedclose to the antennas, and the antenna themselves, the accuracy shall be of 5mm worst case.

LGAs alignment requirements[RFMCK_T#6]The Planck redundant LGAs 2 & 3 shall be inclined as specified in AD02 with an accuracy better than 0.5° (tbc).

Materials[RFMCK_T#7]Full freedom is left to the Contractor to use any kind of material to manufacture each mock-up, considering that theMock-up could be exposed to an external storage. For RF reflectivity purpose, it is explicitely required to cover eachMock-up entirely with an Alu film if the structural material is not metallic.

Bonding[RFMCK_T#8]The bonding resistance between any adjacent metallic structure parts shall be lower than 5 mOhm (to beverified after mock-up assembly).

Antennas access[RFMCK_T#9]As a specific pre-requisite, on PLANCK, a simultaneous feeding of the redundant LGAs2&3 shall be done during thetests. To that aim, a representative set of waveguides (with the ending coupler) will be provided by the customer with
