Modemless transmitter for test vehicle tracking system
First Claim
1. A vehicle test system for recording vehicle data from vehicles traversing a test track, comprising:
- a plurality of locator beacons juxtaposed with the test track for transmitting position signals, each beacon identifying a specific location on the test track, each beacon including;
a transmitter for broadcasting a carrier wave;
a microprocessor controlling the transmitter, wherein the microprocessor energizes the transmitter to indicate a first logical signal and deenergizes the transmitter to indicate a second logical signal, such that the carrier wave remains unmodulated;
the microprocessor controlling the transmitter to repetitively transmit a series of the first and second logical signals which make up a unique identifier code for the beacon, the unique identifier code comprising the position signal for that beacon;
the vehicle test system further including a receiver located within a vehicle traversing the track for receiving the position signal for each beacon as the vehicle traverses the track and a flight recorder located within the vehicle for periodically recording sets of vehicle parameters as the vehicle traverses the test track and the location of the track where the vehicle was at when each set of vehicle parameters was recorded as determined from the received position signals.

Abstract
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.
