Description
In the past 10 years, Thales Alenia Space has developed the three major commercial constellations: GLOBALSTAR2, O3b and IRIDIUM NEXT representing 125 spacecraft on LEO and MEO orbits. Each development has required Avionics enhancement in order to meet the objectives of recurrent cost, radiation environment, in-flight autonomy, or high rate production. Further enhancements of the avionics are being studied to face the new challenges required by the changing Telecom constellation market.
In the first part of the presentation we will review the design and process upgrades applied onto the avionics for these three constellations. In particular we will address the design optimisation, the use of COTS components, the higher integration of the electronics, the validation optimisation and the Satellite autonomy improvement.
The second part of the presentation will deal with the upcoming challenges raised by the mega constellations market. The increased cost saving objectives and need for enhanced on-board autonomy leads to develop new avionics solutions within reduced duration.
