ESA selects SpacePNT GNSS receiver for Genesis Mission
SpacePNT has joined the European Space Agency’s Genesis mission, a navigation satellite project that will be the first to carry all four space-based geodetic techniques on board: GNSS, Satellite Laser Ranging (SLR), Very Large Baseline Interferometry (VLBI) and Doppler Orbitography and Radio-positioning Integrated by Satellite (DORIS).
SpacePNT’s NaviLEO spaceborne GNSS receiver technology was selected for the mission’s critical satellite navigation ranging instrument. Although NaviLEO has flight heritage in low-Earth orbit, it will be adapted for Genesis to operate in medium-Earth orbit at 6,000 km. The system will use a dual-antenna configuration to receive GNSS satellite signals from both zenith- and nadir-looking antennas.
The Genesis mission aims to update the International Terrestrial Reference Frame (ITRF), a global Earth model, targeting an accuracy of 1 mm and long-term stability of 0.1 mm per year. This will provide a precise coordinate system for advanced navigation applications.
