Abstract:
A vehicle, for example, an autonomous vehicle receives signals from a global navigation satellite system (GNSS) and determines accurate location of the vehicle using the GNSS signal. The vehicle performs localization to determine the location of the vehicle as it drives. The autonomous vehicle uses sensor data and a high definition map to determine an accurate location of the autonomous vehicle. The autonomous vehicle uses accurate location of the vehicle to determine RTK corrections that is used for improving GNSS location estimates at a future location. The RTK corrections may be transmitted to other vehicles.

Claim (Index 13):
A computer-implemented method comprising:\n initializing, by a processor of a vehicle configured to receive global navigation satellite system (GNSS) signals, a location of the vehicle and RTK corrections based on the location of the vehicle and raw GNSS signals from the location; and repeating steps comprising:\n receiving, by a GNSS receiver mounted on the vehicle, a raw GNSS signal from the GNSS; \n accessing previously determined RTK corrections by the vehicle; \n determining an accurate GNSS position estimate by applying the previously determined RTK corrections to the raw GNSS signal; \n receiving sensor data captured by sensors mounted on the vehicle; \n accessing at least a portion of high definition (HD) map, the portion describing a geographical region surrounding the vehicle; \n determining a current location of the vehicle in the HD map using the accurate GNSS position estimate; and \n determining new RTK corrections for subsequently determining accurate GNSS position estimates.
