Abstract: This paper describes a flight test program and the resultant navigation performance achieved on an Advanced Development Model (ADM) Ring Laser Gyro Navigator (RLGN) in a Navy A-7E and P-3C aircraft. The RLGN system was developed by the Naval Air Development Center (NAVAIRDEVCEN) under the Advanced Technology Demonstration (ATD) Laser Gyro Program. Initiated in 1976 by the Naval Air Systems Command, the objective of this program is to demonstrate the military utility of laser gyros for aircraft navigation. As the RLGN represents a significant departure from conventional gimballed inertial system technology, a brief functional system description is given highlighting key hardware and software design features. This is followed by a description of the A-7E flight test program, its objective, flight profiles, method of data acquisition and analysis of results. The P-3C flight test program is discussed including a description of the flight test recording instrumentation, flight profiles, data reduction, and analysis of results. An indication of system reliability, maintenance, and calibration actions versus system design goals is given. Effects of high latitude on system alignment and navigation performance are also highlighted.
