Embedded GPS - The Canadian Marconi Approach

James M. Brown , Patrick J. Hui

Abstract:	This paper will present a new, embeddable GPS card set from Canadian Marconi. This GPS sensor is designated the CMA-2122. It uses the same software algorithms and very similar hardware architecture as the earlier CMA-786 GPS Navigation Receiver which was described in a paper given at the 1987 ION Conference in Colorado Springs. Three circuit cards totalling 50 square inches and consuming only 7.5 watts typical implement a complete 2-channel GPS sensor suitable for embedding in other avionics navigation equipment, land vehicle navigation equipment or time transfer devices. A high speed 8-bit parallel Interface and an RS-232 interface are provided to facilitate this integration. A separate power supply, mechanical housing and antenna/pre-amp (all available from Canadian Marconi) are required. Satellite acquisition and tracking algorithms, Kalman filter and Navigation software, and hardware implementation will all be described in this paper.
