abstract: Due to the strong growth of MEMS technology, the Inertial Navigation System (INS) is wi del y applie d to navi gati on and g ui dan ce of aircraft movements. However, there are existing errors in the accelerometer and gyroscope signals that cause unacceptable drifts. To minimize these effect s on the INS syste m, a GPS is u sually employed simultaneously with an INS in order to increase the dimension of the system; the desired parameters are estimated by the Kalman filtering technique applied to the enlarged system. In this paper, we prese nt a st ruct ure con sistin g of a Kal man Filter (KF) of whi ch t he input is the difference between the noisy INS output and the noisy GPS output; the output of KF is finally introduced into the unaided INS system. In this structure, INS errors are compensated by a feedforward and a feedback loop. The overall performance of the system is analyzed by simulation; and results show that this technique substantially improves the quality of the navigation and guidance systems.
