With over 200 years of combined on-orbit performance and a heritage of 20 years in spaceflight, the receiver offers reliable position, velocity, and time data. Its architecture includes 12 tracking channels, dual-antenna capability, and enhanced radiation-hardened digital electronics. Supporting RS-422 and MIL-STD-1553 interfaces, the receiver ensures robust operation with features like autonomous cold-start mode, low signal acquisition, and integrated carrier phase tracking. Compact and lightweight, it operates at 20-35 VDC, making it ideal for demanding space missions.gdmissionsystems.com /products/communications/spaceborne-communications/spaceborne-gps-receivers/viceroy-gps-receiver Viceroy GPS Receiver – General Dynamics Mission Systems 4-5 minutes Viceroy GPS Reciver Superior positioning with 200+ years of on-orbit performance Design based on legacy space qualified digital design 20 years of trouble-free spaceflight heritage Same reliable position, velocity, time, pseudorange and carrier phase at 1Hz Same form-factor and interface control as heritage Viceroy receiver Features General Dynamics’ Viceroy-4 Global Positioning System (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 MILSTD-1553 bus interfaces.
