VEHICLE POSITION ACCURACY ENHANCEMENT SYSTEM

The invention relates to a vehicle position accuracy enhancement system. The invention provides a vehicle position accuracy enhancement system. A digital active phased array radar is configured to generate a surveying topography including topographic altitude information. The controller is configured to implement operational instructions in the memory to perform mapping matching between the generated mapped terrain from the at least one digital active phased array radar and terrain altitude mapping information in the terrain database to determine a mapping position solution. The controller is further configured to augment a sensor position solution from at least one other position determination system, including GNSS, with at least a mapping position solution to enhance the accuracy of the sensor position solution. The controller is also configured to: determine a position error in the GNSS based on the mapping position solution; and broadcasting the determined position error. 本发明题为运载工具位置准确度增强系统。本发明提供了一种运载工具位
