The objective of the MARLISAT project was to further develop Marine Plastic Monitoring through the use of multiple satellite technologies. In effect, the intention was to use satellite technology to detect Marine litter, track it and forecast it pathways. 4 satellite technologies were combined:

This project, renamed ACROSS (Asteroid Collaborative Research by Occultation Systematic Survey), aimed at considerably improving the predictability of stellar occultations by small and difficult targets such as the Near Earth Asteroids (NEAs). In particular, it focused on the binary asteroid 65803 Didymos, target of the DART (NASA) and Hera (ESA) missions, and other NEAs: either secondary targets of Hera, or NEAs whose orbit is accurate enough. Stellar occultations are an unbeatable approach to:

SAVOIR has produced a set of generic specification under the form of documents, based on some physical architecture of equipment that was state of the art at that time. The new functional model based approach is more based on functional chains and models. It is expected that modelling the SAVOIR avionics architecture and generic specification using the MBSE techniques, in particular Arcadia method and Capella tool, will allow to have an innovative standpoint on the SAVOIR standardisation.

The Doherty concept has proven to be a very effective technique for designing amplifiers, which maintain a high efficiency over a wide range of operating conditions. This technique is extensively used in terrestrial applications like base stations where power efficiency is getting more and more attention. Power efficiency is also of concern for space and the Doherty concept could certainly help in designing more efficient PAs. Ka-band is now being considered for mobile services that could offer very high capacity as compared to the existing ones at L-band.
