Abstract: Systems and methods for GNSS anti-jamming using interference cancellation are described herein. In certain embodiments, a system includes an antenna that receives signals, wherein the signals comprise a weak portion associated with one or more GNSS satellites and a strong interference portion from an interfering signal source. The system also includes a GNSS anti-jammer. The GNSS anti-jammer includes an interference isolator that receives the received signals and provides an estimated strong interference portion as an output. The GNSS anti-jammer also includes a summer that subtracts the estimated strong interference portion from the received signals to create a summed signal. Further, the GNSS anti-jammer includes a local noise remover that removes noise generated by the interference isolator from the summed signal, wherein the local noise remover is a processor that digitally removes the noise. Further, the system includes a GNSS receiver coupled to receive the summed signal from the processor.

Abstract: Disclosed are methods, systems, and non-transitory computer-readable medium for vehicle navigation processing. For instance, the method may include scanning for one or more terminals within a predetermined vicinity of the vehicle via a low latency communication network and receiving positional data of the one or more terminals via the low latency communication network. The method may further include receiving directional data of the one or more terminals relative to the vehicle, determining a first location of the vehicle relative to the one or more terminals based on the directional data, and determining a second location of the vehicle relative to the environment based on the positional data and the first location.

Abstract: Disclosed are methods, systems, and non-transitory computer-readable medium for distributed vehicle navigation processing for a vehicle. For instance, the method may include: by the vehicle: obtaining reference data from one or a combination of an imaging system, an antenna system, and/or a radar system of the vehicle; in response to obtaining the reference data, determining whether a GNSS signal is below a threshold; and in response to determining the GNSS signal is below the threshold, transmitting a navigation supplementation request message including the reference data to an edge node or a cloud node. By the edge node or the cloud node: in response to receiving the navigation supplementation request message from the vehicle, performing a position resolution process to determine and transmit a position of the vehicle by one or more functions. By the vehicle: performing a navigation control process based on the determined position.
