The objective of the study has been is to evaluate the expected performances of on-board GNSS receivers in GTO and HEO trajectories. These types of orbits/trajectories will be encountered during orbit raising of future all-EP telecommunication satellites. The trajectories, often optimized for minimum flight time, present specific challenges to the use of on-board GNSS. These include a large variation in visibility patterns and RF power levels, a high dynamic range of GNSS signals and varying spacecraft attitude resulting in masking effects affecting antenna gain.

This project has studied the possibility of improvement of the classical regulated bus by considering the use of a classical regulated topology whose voltage is regulated to maximum power point of the solar array. The project has consisted of two phases: the first one considered whether the basic idea improves the classical regulated bus by using ad hoc developed models; the second one, after positive conclusions of the first, tested the actual behaviour of a low power mock-up of the proposed idea.

Space industry is based increasingly on full electric propulsion systems, and there is a European need to anticipate future missions. 2018 full electric propulsion Telecom satellites have a relatively low thrust and need several months (6 to 9) to rise from GTO to GEO, which is their main drawback.

AlN is an interesting new material for TWTs. Nevertheless, the requirements for space, like long-term stability and reliability are stringent for the AlN and need to be secured. This requires a good understanding of the material and the knowledge of the complete processing, including the material source. Long-term reliability had been fostered by a common approach – together with the supplier.
The developed product is a Technology Demonstrator of the Metal Hydride (MH) Hydrogen and Heat Storage System for use in future telecom satellites as part of a Regenerative Fuel Cell System. Thermal management is one of the key challenges with the RFCS, due to the significant amount of fuel cell waste heat that must be dissipated, which has a big impact on the total system mass and volume. By using a metal hydride system for hydrogen storage, waste heat from the fuel cell can be stored in the metal hydride material, and later rejected with a lower heat flux, over a longer time span.
