The Position and Azimuth Determining System PADS maintenance concept is formulated on the use of automatic built-in test equipment BITE to analyze and verify system malfunctions at the organizational level. Upon verification of a system failure, direct or general support Contact Teams will make contact and use BITE to isolate the malfunction to a line replaceable unit LRU. The malfunctioning LRU is then returned to the general support maintenance level for repair. A special test equipment STE configuration employing an automatic software diagnostic program technique is then used to isolate LRU malfunctions to the replaceable module level, and to verify LRU operation after replacement of the faulty module. This combination of BITE and STE diagnostics offers cost-effectivity, minimal operator skill requirements, and a tactically feasible solution to maintaining the PADS in a field Army environment.
