Abstract
A method, system, and computer program product to provide accurate positioning of a vehicle while conserving power is provided. The system includes a receiver configured to receive a positioning signal that determines a position of the vehicle and an auxiliary sensor configured to provide data to supplement the positioning signal so as to provide the position of the vehicle more accurately than with using solely the positioning signal. The system also includes an auxiliary controller coupled to the auxiliary sensor. The auxiliary controller is configured to generate a first signal to power-up the auxiliary sensor if the vehicle is proximate to entering an area that reduces accuracy of the positioning signal, and calibrate the auxiliary sensor prior to the vehicle entering the area; and generate a second signal to power-down the auxiliary sensor if the vehicle is proximate to exiting the area.
