General Relativity Experiment with Galileo satellites 5 and 6 (GREAT)

The GREAT project provides an improved test of Einstein's theory of general telativity by analysing the relativistic gravitational redshift as observed in the clock data from GSAT-0201 and GSAT-0202. These satellites have been injected into highly eccentric orbits following a launch mishap, providing us with the unique chance to perform an important test of fundamental physics.

Future Concepts for Galileo Search-and-Rescue Space and Ground Segment (Parallel a)

MEOSAR is a system designed to locate emergency beacons anywhere on the Earth in order to coordinate rescue efforts for people, vehicles and facilities in distress. It works by evaluating the time and the frequency of the beacon signal upon arrival at the receiver. From these the relative distance and velocity of the sender can be calculated if sufficient data points have been collected. It is beneficial to receive the beacon on several different spacecraft to optimise the accuracy of the trace.
