About
GEORIX is a high-performance, multi-constellation GNSS receiver. With an accuracy of less than 20 meters in GEO, GEORIX sets a new standard for precision on-board real-time navigation.
GEORIX incorporates a GEO-optimized antenna, detached Low Noise Amplifiers (LNAs), and advanced technology such as an accurate force model-based orbit propagator and state-of-the-art Kalman filtering.
GEORIX offers a flexible acquisition and tracking concept, single-frequency signal processing of up to 12 satellites, a sliding search window for minimized acquisition times, and Doppler-based loop aiding.
GEORIX is highly configurable and features a powerful parameter interface that supports changes in both standby and operational modes. Additional data products provide excellent visibility of receiver internals.
