News Flash: Maiden flight of new generation navigation receiver

Since November 2020 two new Precise Orbit Determination Receivers (PODRIX) from RUAG Space are in orbit. They determine the position of ocean-monitoring satellite Sentinel-6. The PODRIX GNSS spaceborne receiver achieves a very high, real-time in-orbit accuracy of the satellite’s position in orbit from below one meter to a few centimeters utilizing on-ground post-processing. The high accuracy is achieved through simultaneously processing of multi-frequency signals from the U.S. GPS satellites and the European constellation of navigation satellites called Galileo. PODRIX GNSS spaceborne receivers are built on the experience of the more than 20 GPS-only receivers of the RUAG Space legacy receiver generation that are currently in orbit. GNSS stands for global navigation satellite system.

Why does the position of a satellite matter?

Without knowing the satellite’s position in orbit, the satellite would be useless. Navigation receivers from RUAG Space precisely determine the position of a satellite once in orbit. The better one knows the satellite’s position in orbit, the better the data the satellite can deliver. Take the European ocean-measuring satellite Sentinel-6 as an example. The satellite measures the sea level on a global scale with unprecedented accuracy, which is crucial for climate change research. Every mm or cm in further precision highly improves the performance of the mission. The more precise the Sentinel-6 spaceborne GNSS receiver from RUAG Space works, the more precise are the data of this climate mission.

What is GNSS? What does a GNSS receiver?

GNSS is an acronym for Global Navigation Satellite System. The space segment of GNSS is a constellation (a higher number) of satellites, which provide signals to GNSS receivers. The receivers, like the spaceborne GNSS receivers from RUAG Space, then use these signals to determine their position, velocity and time. Examples for Global Navigation Satellite Systems are the GPS (Global Positioning System) from USA, Galileo from the European Union, GLONASS from Russia or BeiDou from China.
