A system determines the azimuth of a source of an interfering signal. The system steers a first null beam in the direction of transmitting device and also steers a second null beam in the direction of the interfering source producing and providing the interfering signal. The system measures an angle to the first null beam. The system also measures an angle to the second null beam. The system calculates the azimuth of the antenna based on the measured angle to the first null beam and a known absolute bearing of the transmitting device. The system calculates the azimuth of the interfering source based on the measured angle to the second null beam and the previously calculated azimuth of the antenna.

System and method for determining azimuth of a source of an interfering signal using a beam steering antenna

A low-latency centralized RTK system utilizes an RTK server to perform matched updates using base station GNSS measurements from one or more base stations and GNSS measurements from one or more rovers, and the one or more rovers produce RTK solutions based on the results of the matched updates. The RTK server includes one or more processors that perform the matched updates and a transmitter that transmits at least the ambiguities to the rovers. The respective rovers, which have processing power that is sufficient to quickly calculate RTK baselines, utilize the received ambiguities, the base station GNSS measurements received from either the RTK server or the base stations, known base station positions and instantaneous GNSS measurements at the rovers to readily determine and update their RTK baselines and their precise positions.
