GROUND STATIONS Provide Enhanced Control of GPSⅢ Satellites

摘要

in support OF the launch of the first, next-generation GPS Ⅲ satellite (GPS Ⅲ SV01) by Lockheed Martin, Raytheon Co. has developed the GPS Next-Generation Control System (GPS OCX) for maneuvering and controlling the orbiting satellite. Achieving the final, precise orbit for this timing/position-location satellite is a painstaking operation that requires 10 or more days to accomplish using the GPS OCX. "The GPS OCX Block 0 launch and checkout system is foundational to the improved precision, navigation and timing of the entire constellation," said Dave Wajsgras, president of Raytheon Intelligence, Information, and Services, "and we'll all benefit from the system's unprecedented level of cybersecurity protections."
