Key highlights
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.
