Integrated INS/GPS Navigation System

Abstract

Navigation equipment specifications differs in the update rate, accuracy, budget, reliability, size and mass. In some applications in order to meet navigation system requirement, a dead reckoning equipment i.e. Inertial Navigation System INS is could be integrated with one or many position fixing equipment, i.e. Global Navigation Satellite System GNSS. INS and GPS have different benefits and drawbacks, and they complement each other when integrating them to provide a navigation solution with higher bandwidth, and long-term and short-term accuracy. This research investigates the performance of an integrated system GPS/INS(MEMS) when changing the algorithm update rate, and compare between different integration algorithm namely loosely and tightly integration.
