The activity aims to develop techniques (e.g. high sensitivity algorithms, data wipe off for Galileo, optimal data plus pilot combinations etc.) in order to enhance the capability of mass market receivers taking into account their typical resources constraints (limited power, memory, open loop platform etc...). The activity shall investigate the application of these techniques for phase and code tracking down to the detailed design of the techniques for different type of usage and in different type of environment.

Open GNSS signal authentication is one of the main future challenges that the GNSS community will have to face in order to support safety critical applications. One of the major evolutions proposed for the Satellite Based Augmentation Systems (SBAS) systems is to provide authentication services to their users. This evolution is still under debate in international fora, therefore this activity proposes to investigate the issue starting from the consolidation of the spoofing scenarios and the potential anti-spoofing techniques that can be integrated in an airborne navigation system.

The outcome of the activity was a conceptual design that has been assessed feasible and can be implemented in a follow-up activity.

The first steps have been taken to establish a non-explosive, harmless Indium-based 100W electric propulsion system for small and medium satellites. The activity successfully developed a breadboard that included all necessary functions for controlling a micro thruster, including temperature sensing and control, generation of the high voltage supplies for the ion emitter and extractor as well as heating and bias voltage supply for the charge balancing.

Within the framework of ESA’s Alcantara initiative international R&D Studies were funded.
