Abstract—This paper presents a novel algorithm named Street Tracking Algorithm (STA) for performance improving of a low-cost INS/GPS integrated System. Instead of the open-loop output position calculating method in the developed INS/GPS integrated systems, this STA calculates position based on three parameters of INS position output, IMU velocity increment within a time slot and the trajectory’s digital map database. The position error of this STA reaches ± 2.5 meters within a considered period time slot of 28 seconds. This error is much improved up to 80 times when compare with the original INS/GPS integrated system.
Index Terms—inertial navigation system, global positioning system, kalman filter, street tracking algorithm.
