ABSTRACT:
Conventionally, high-speed cameras are used to record the ejection of a store from an aircraft. The subsequent processing and analysis of the high-speed films are usually quite costly. The present invention system substantially reduces the cost of such processing and analysis by implementing a plurality of electro-optic sensors to detect sequentially individually energized LEDs mounted onto the to be ejected store. To sequentially activate the LEDs, receiver decoder electronics, located on the store, are used--provided signals are sent thereto by a radio control transmitter located in the aircraft. By formatting the data received by the electro-optic sensors, the different positional characteristics, such as the pitch rate, the velocity, the yaw rate and the roll rate, can be calculated in real time, either on board of the aircraft or at a remote location, the raw data having been transmitted thereto by means of a telemetry system, also located within the aircraft. The operation of the electro-optic sensors, the radio transmitter and the telemetry system are controlled by a processor.
