On the Use of a Single Channel GPS Receiver in a Dynamic Environment

John Brading, Michael Foss, Paul Turney

Abstract:	For a number of years, the Precision Products Division of the Northrop Corporation has been developing integrated GPS/INS systems using low cost tactical sensors and single channel GPS receivers. Our tactical grade sensors have not only been used in our systems, but in a number of other GPS/INS integration activities. The aim of all of these systems has been to provide optimum navigation in a diverse environment at the lowest possible cost. In the development of our systems, we have become aware that the integration of a GPS receiver and an inertial system requires a highly integrated approach, affecting the design of the GPS receiver's loop architecture to the design of the navigation filter. The ability to perform a proper integration has to be designed into the equipment, and can only truly be achieved if the fundamental difficulties of GPS and INS integration are addressed at the earliest stages of subsystem and system design. This paper describes specific issues that must be considered in the design of an optimally integrated system.
