The objective of the proposed PNT Traffic Light project is to develop a continuous 24/7 performance monitoring tool for EGNOS/GNSS (and particularly for GPS, GALILEO and EGNOS) on the northern and arctic region of, at least, EGNOS coverage area. In addition to just EGNOS, the tool shall be designed to support assessment of the performance of also other GNSSs (at least GPS and Galileo).

While the MEOSAR is moving to FOC with Galileo satellites that are equipped with SAR transparent payloads, ESA is already investigating its future Galileo-2 (G2G) system for new features. In this framework, one of the aims of the ESA study on Future Concepts for Galileo Search And Rescue was to define a preliminary design of a new SAR payload capable of processing both First Generation Beacon (FGB) and future Second Generation Beacon (SGB) signals.

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.
