Fulltext: AC021111.PDF (237.34KB) Isi artikel This study describes a preprocessing scheme for stabilizing a measurement of cascaded GPS/INS integration Kalman filter. A smoothing of the measurement and a prediction of INS error are proposed for an abrupt error jump of GPS solution and a blocking condition of GPS signal, respectively. The smoothing algorithm is designed by a gain scheduling with fuzzy logic. The prediction scheme is derived by Schuler model of INS. The test results show the high efficiency of the suggested algorithm. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
