Airborne GPS/INS Capability for the Australian Defence Force: The FMS-800 Integrated with the LTN-92

G. Phil Barnes, M. Jay Little

Abstract:	Collins Avionics & Communications Division (CACD) is under contract to Boeing Australia Ltd. to modify and supply a Y-code GPS system for integration into Australian Defence Force (ADF) C-130H, Boeing 707, and HS748 aircraft. The system being modified is based on that being developed for the USAF KC-10 aircraft with additional features and functionality. This paper presents a short summary of the program, integration requirements and unique functionality required by the ADF, followed by flight test results of the Integrated Navigation and In-Flight Align features of the system. The FMS-800 as installed comprises multiple Control Display Units (CDU-900Gs) with embedded Y-code GPS, one or two Bus Subsystem Interface Units (BSIUs) for integration with existing flight instruments and aircraft subsystems, a PC-Card based Data Loading and Recording Subsystem, and interfaces to LTN-92 Inertial Navigation Systems already installed in the aircraft. The CDU-900G provides Receiver Autonomous Integrating Monitoring and GPS approach capabilities in accordance with the requirements of TSO C129. In March 1997, a number of flight tests of the system were conducted in a company Saberliner 50 aircraft. The tests included stationary and In-Flight alignments of the LTN-92, GPS tracking performance and validation of the Inte-grated Navigation solution under a variety of conditions. Results of the flight test are presented and discussed.
