Describes the GPS/inertial navigation system (GPSI) integration potential of a low cost inertial measurement unit (IMU) consisting of micro-machined sensors and on board calibration. Two simulated case studies demonstrate the IMU's performance in both flight and automotive navigation. Both studies show that the IMU can be successfully integrated with Kalman filtering into a GPSI system. With complete loss of GPS signals, position accuracy is shown to be less than 10 meters, 2 distance root mean square (drms), after 30 seconds.
