General Dynamics Sentinel M-Code Space GPS Receiver Outperforming Requirements In-orbit

With missions that grow more complex every day, the need to provide a resilient solution for space GPS users has never been more urgent. General Dynamics Mission Systems solves this challenge with the Sentinel® family of M-Code Space GPS receivers. Recently launched into space, and performing at a level exceeding customer requirements, the M-Code GPS receiver counters jamming and spoofing threats, and delivers uninterrupted high-accuracy Positioning, Navigation and Timing (PNT) data for critical space missions.

Sentinel® is the only GPS Directorate (GPSD) security certified M-Code Space GPS receiver commercially available for DoD procurements. Adding to the M-Code GPS family is the new Sentinel®-Lite receiver. By leveraging the robust technical and manufacturing infrastructure established for our standard Sentinel®, General Dynamics Mission Systems has engineered an M-Code Space GPS receiver capable of supporting short-term missions while delivering the same high accuracy PNT data, and the same resiliency and performance as the standard Sentinel®, but at a price aligned with shorter mission duration.

Using 32 signal processing channels, the receiver provides precision positioning, velocity and time information in all orbit regimes including LEO, GEO, MEO and HEO. Sentinel® improves on the SWAP (size, weight, and power) of previously available General Dynamics space receivers while improving resiliency with its internal anti-jam and anti-spoof algorithms. Sentinel® fulfills the national mandate to transition all of DoD to the more secure and jam-resistant M-Code signal.
