Abstract:

A system and method of calibrating satellite signals broadcast by one or more satellites of a satellite positioning system. The system receives sensor data from one or more sensors provided on a vehicle. The system further detects satellite signals from the one or more satellites, and determines timing offsets associated with the satellite signals from each of the one or more satellites based at least in part on the sensor data. For example, the one or more sensors may include at least one of a camera or a rangefinder, and the sensor data may correspond to a three-dimensional sensor image that may be used to determine a location of the vehicle.
