Abstract
A GNSS receiver and antenna system transmits signals from an antenna structure to a remote GNSS receiver and includes a digital communications subsystem that utilizes a high speed digital communications conductor. The transmissions are digital signals that preserve GNSS satellite signal frequency and/or carrier and code phase information. The system may transmit digital signals corresponding to GNSS signals such as GPS, GLONAS, Galileo and Compass satellite signals. In addition, the system may transmit, over the same digital communications conductor in appropriately formatted digital signals, ranging signals from ground-based transmitters or other satellites, differential GNSS correction signals from beacons or base GPS receivers, and/or signals from transmitting or co-located sensors, such as inertial sensors, temperature sensors and so forth. The digital signals include in headers or payload relative timing and carrier and code phase information and, as appropriate, information that identifies the signals by source or type, such as information that identifies the frequencies or the antennas or antenna elements providing the respective signals.
