Space

Although originally designed to serve terrestrial users, today, GNSS also plays an important role in many space applications. Whether used for telecommunications, Earth Observation, research or navigation, Earth-orbiting satellites rely on the real-time positioning and timing provided by GNSS. Thanks to GNSS, these missions can reduce costs, improve navigation performance, and ensure the provision of trustworthy data and services.

GNSS works on the Moon!

A GNSS receiver has successfully tracked Galileo and GPS signals and computed on board the Navigation Solution during lunar orbit and on the Moon's surface. This mission proved that Global Navigation Satellite System (GNSS) signals can be acquired, tracked and even used for positioning on the Moon!

Where are they now?

Leveraging the support they received via the CASSINI initiative, companies of all shapes and sizes have gone on to develop some very cool space-based solutions.

EU SST is the European operational capability that safeguards the space assets of the EU, especially the satellites involved in the EU Space Programme, its Member States and other space operators.

Space Surveillance and Tracking: a global challenge

The EU Space Surveillance and Tracking (EU SST) contributes to ensuring the safety and sustainability of space activities, offering services to a growing community of worldwide users. Managed by EUSPA, the EU SST Front Desk is the interface for the provision of the SST services, which currently protect more than 400 satellites.
