GNSS receivers for orbit positioning and time as part of a satellite payload

LEO satellites are being launched by the thousands and they are changing the way we connect to the internet, observe the Earth and deliver PNT (Positioning, Navigation and Time). These satellites move at an astonishing speed of almost 8 km/s, which can pose an issue for standard COTS receivers. Septentrio is pioneering robust space-ready GNSS receivers, with a possibility to remove COCOM limits, allowing the receiver to move very fast at high altitudes. These receivers have a low power consumption, which is important especially when multiple receivers are required in a single payload.

Septentrio has been a close partner of European Space Agency (ESA) since the beginning of the Galileo Space Program. The first GNSS receiver ever to receive live Galileo signals was built by our team of dedicated engineers.

Earth observation

The closer proximity to the Earth opens the possibility for continuous Earth observation by LEO satellites. High accuracy positioning is needed for referencing and stitching of data or images taken from such far distances. Septentrio receivers offer a high update rate and low latency ensuring that the satellite has the most accurate positions even at very high speed.

Network communication

Communication or internet satellites need accurate time for synchronization. The mosaic-T compact time receiver module delivers accurate and reliable GNSS time with nanosecond accuracy. It offers dedicated timing features and inputs for time synchronization.

PVT: constellation for positioning information

Certain LEO satellite systems offer positioning services for a variety of applications on the ground. These satellites need to know their orbit position with high accuracy as well as accurate time. Septentrio space-ready receivers have proven to acquire and track GNSS signals even at very high speeds, which enables them to reliably deliver accurate positioning and time for LEO satellite. These receivers are able to handle the very high doppler frequency of GNSS signals, which is a consequence of moving at extremely high speeds.

With over two decades of experience in multi-constellation multi-frequency technology, Septentrio is on the frontier of the LEO satellite era. We are open to redefining high-accuracy positioning with new satellite systems and signals as they become available.
