摘　　要：由于车载GPS/DR组合导航系统模型存在参数不确定性,Kalman滤波技术要求准确的系统模型和确切己知的外部干扰信号的统计特性;而Minimax滤波技术则对此不敏感,具有较强的鲁棒性。提出将Minimax滤波技术应用于车载GPS/DR组合导航系统中。蒙特卡洛仿真表明,Minimax滤波技术取得了预期的滤波效果。There is uncertainty in the model of GPS/DR integrated navigation system.The technique of Kalman filter requires accurateness of system model and the known statistics of outer interrupt signal.Minimax filter is insemitive to them and with great robustness.The Minimax fil- ter is applied for GPS/DR integrated navigation system.Monte Carlo simulations show that Minimax filter has acquired expected filter result.
