The aim of the proposed development is to improve the frequency flexibility of the Thales Alenia Space France (TAS-F) generic Command Receiver Product.
At system level, the main interest is to offer flexibility to the operators in the following cases:
The objective is to propose this frequency flexibility capability keeping roughly the same recurring price at unit level.
The current Thales Alenia Space product has a capability in terms of frequency agility limited to some frequency in the range of 7.5MHz. For higher range, a dual front end version can be proposed.
The target of the development was to widen the frequency range agility up to 750MHz with a single front end receiver in order to cover, for example, the whole RF Ku band 13.75GHz to 14.5GHz.
Such frequency flexibility can easily be considered for the C, K or Ka band version of the TAS product without major impact.
The frequency step obtained is 100kHz which covers all the operators step requirement.
To implement wide band flexible local oscillator based on fractional synthesizer in the current TAS command receiver without any drawback on performances.
Moreover all modules of standard product are re-used and the new LO has no impact on the housing of the unit.
The flexibility extension of the TAS-F standard product has been successfully demonstrated through this development.
This new version FF TTC Rx has been successfully proposed in a new satellite program for a major telecom operator.
The proposed solution consists in modifying some functions of the current standard product.
These functions are highlighted in green in the next block diagram:
The development aims:
The interface will be developed in the frame of specific programs as it is dedicated to a specific platform.
The TO of the contract was in May 2010. The development plan was as follows:
The final review was successfully held in December 2012.
The FF receiver has successfully passed the qualification (electrical test in thermal vacuum, vibration, shock, EMC) in frequency modulation mode. It has been retrofit in PM mode and successfully passed the delta acceptance test.
This development has already resulted in the first commercial sales of the FF TTC Rx.
