The Global Differential GPS (GDGPS) System is a complete, highly accurate, and extremely robust real-time GNSS monitoring and augmentation system.
Employing a large ground network of real-time reference receivers, innovative network architecture, and real-time data processing software, the GDGPS System provides sub-decimeter (<10 cm) positioning accuracy and sub-nanosecond time transfer accuracy anywhere in the world, on the ground, in the air, and in space, independent of local infrastructure.
A complete array of real-time GNSS state information, environmental data, and ancillary products are available in support of the GNSS Augmentation operations, Assisted GNSS (A-GNSS) services, situational assessment, and environmental monitoring — globally, uniformly, accurately, and reliably.
Full services are available for GPS, GLONASS, BeiDou, Galileo, QZSS, and NAVIC.
GDGPS has been providing high reliability position, navigation, and timing data services to industry and government operations since 2000. The GDGPS navigation technology underlies major global infrastructure, including the Wide Area Augmentation System (WAAS), and the former next generation GPS Operational Control Segment (OCX).
