Abstract: A system for detection and reporting of data signal interference includes a plurality of vehicles. Each vehicle includes a global navigation satellite system (GNSS) receiver receiving a GNSS signal, a cellular modem configured for sending and receiving data over a wireless communication network, and a computerized detection and reporting controller. The controller includes programming to monitor the GNSS signal, analyze the GNSS signal to identify a presence of radio frequency (RF) interference, and generate a report of an RF interference event to a remote server device based upon the presence of the interference. The system further includes the server device including programming to monitor the report of the interference event from each of the vehicles, identify a threshold RF interference event based upon the report of the RF interference event from each of the plurality of vehicles, and command a remedial action based upon the threshold RF interference event.

Abstract: A method of determining the position of a vehicle includes generating a vehicle-based point cloud of objects in proximity to the vehicle, referenced to a vehicle-based coordinate system. The method also includes receiving an infrastructure-based point cloud, referenced to a global coordinate system, of objects detected by a camera mounted at a fixed location external to the vehicle, and registering the vehicle-based point cloud with the infrastructure-based point cloud to determine the vehicle position in the global coordinate system.
