General Dynamics’ Viceroy GPS Spaceborne Receiver provides 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 18 GPS channels can be assigned to either antenna. The design supports RS-422 or MIL-STD-1553 bus interfaces.
