Spaceborne GPS Receivers

20+ Years of providing GPS Receivers for Satellites

General Dynamics has a 20+ year legacy of providing high-reliability space-hardened global positioning system (GPS) sensors for commercial and military low-earth orbit (LEO) users. Our Viceroy and Monarch receiver families have flown innumerable LEO missions and some geo-synchronous Earth orbit (GEO) missions and continue to provide reliable data to the commercial, military and NASA user communities.

Explorer GPS Receiver

General Dynamics’ Explorer Global Positioning System (GPS) Spaceborne Receiver provides position, velocity, and time information for Low Earth Orbit (LEO) and Geostationary Earth Orbit (GEO) applications. The Explorer GPS Receiver includes all the features of our heritage Viceroy GPS Receiver.

Viceroy GPS Receiver

The Viceroy GPS Spaceborne Receiver has the most on orbit heritage of any commercial GPS Receiver on the market. The Viceroy provides position, velocity and time information for low Earth orbiting satellites.

Sentinel M-Code Receiver

General Dynamics’ Sentinel™ M-Code GPS Receiver provides Precise Positioning Service position, velocity, and time information for Low Earth Orbit (LEO) and Geostationary Earth Orbit (GEO) applications. Performance and satellite visibility are enhanced through the use of dual antennas; each of the 64 GPS channels can be assigned to either antenna.

Monarch-M Receiver

General Dynamics' Monarch-M (formerly M-Code) provides Precise Positioning Service position, velocity, and time information for Department of Defense Low Earth Orbit (LEO) and GEO applications. Performance and satellite visibility are enhanced through the use of dual antennas; each of the 32 GPS channels can be assigned to either antenna.
