The introduction of the Global Positioning System (GPS) will make possible the design of systems for land navigation with a positional accuracy as good as the best inertial systems currently available, but at a fraction of their cost. Although a feature of the GPS design is resistance to jamming, complete immunity is unlikely. A GPS only fit is therefore not acceptable where continuous knowledge of position and steering data is required. One possible solution is a hybrid system comprising GPS and a low performance, low cost Inertial Navigation System (INS), using a Kalman Filter to optimise the accuracy. The complementary nature of the error patterns for GPS and INS should make this a very effective solution, with the added advantage of system redundancy. This paper reviews the land navigation requirement, discusses the benefits of a hybrid solution and includes simulated performance.
