A system for recording vehicle data from vehicles traversing a test track includes a plurality of locator beacons buried in respective well casings around the test track for transmitting location signals. Each beacon includes a transmitter and a microprocessor that controls the transmitter. Receivers are disposed in the test vehicles for receiving the location signals as the vehicles pass by the beacons, and a respective computer receives the position signals from each receiver and formats the signals as appropriate for the vehicle's onboard flight recorder. Then, after checking for signal fidelity the computer sends each signal to the flight recorder, which time stamps the position signals along with other data collected from the vehicle. In this way, data can be correlated to particular segments of the test track.
