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 Synergetic Air-Breathing Rocket Engine (SABRE) has the potential to allow the development of space launch systems which provide a step change in reusability, reliability and cost-per-kg to orbit. Whilst ground based development of SABRE core engine and rocket elements is progressing, flight testing of the SABRE nacelle elements is seen as most appropriate approach to raising their TRL to allow acceptable risk flight testing of an entire SABRE propulsion unit.

Increasingly demanding space-based applications require a large primary mirror diameter, on which the optical instrument resolution depends. However, the mass and volume of a monolithic primary mirror would dramatically increase along with its size, which, in addition to cost and technical issues, is also limited by the available volumen in the launch vehicle fairing.

The study demonstrates that in an emergency situation, with only a very short warning time, the launch of a fast asteroid kinetic deflection mission is feasible (targeting launch-readiness in six months!), given that certain identified pre-requisites have been prepared well in advance. The capabilities and requirements of 'hijacking' and modifying a commercial spacecraft platform in order to perform asteroid kinetic deflection in the shortest possible time were consequently assessed.

Background and justification: Space environment includes severe radiation and plasma storms - driven by solar activity and its effect on the Earth’s magnetosphere – affecting satellite systems.

A GSTP De-Risk Framework with RUAG Space Germany designed and demonstrated a novel, compact and robust sensor head for angular sensors for space mechanisms, using modern and advanced materials and manufacturing methods.

The final performance tests provided evidence in terms of high precision manufacturability of ceramic packages.

The robust design was found to be suitable for the harsh space environment
