Described is the test and evaluation of an airborne multilateration-distance measuring equipment DME position reference system to be used with a long range navigation LORAN-C data collection system. The system, Remote Area Precision Position System RAPPS, was developed by Amex Systems, Incorporated under an Federal Aviation Administration FAASystems Research and Development Service SRDS contract. In August 1979, the FAA Technical Center determined system accuracy using a Convair 580 aircraft as a test platform. Space position measurement of the aircraft was determined by the Center Nike-Hercules radar. When the range biases of the four DME ground stations were removed by postflight computation, flight test results from orbits about the Atlantic City DME beacon indicated a standard deviation error of 256 feet about a mean range error of 345 feet. Operational evaluation of the RAPPS airborne and ground subsystems was conducted during the winter in Vermont. The field evaluation determined that both the ground and airborne subsystems have significant design deficiencies of the hardwaresoftware. Author
