The present invention relates to a system for managing assets such as vehicles and/or equipment in an area such as a repair yard or parking lot. A plurality of mobile devices periodically wake-up at different times and transmit their uncorrected GPS location data to one or more fixed local devices. Each fixed local device periodically forwards its accumulated, uncorrected GPS data for each mobile device to a reference device. A reference device is precisely located and capable of differentially correcting the data and forwarding the corrected result sets either back to the local devices and/or to third parties.
