摘要
Abstract
Inertial sensor based on microelectromechanical system(MEMS)with its advantage of low cost,low power consumption and small volume is widely used,low-cost inertial sensor maked the MEMS/GNSS integrated navigation systems have a great space of development.Compared with the GNSS,MEMS had better performance in the face of signal interference,however,the MEMS gyroscope and accelerometer precision often effected by gyro and acceleration measurement error.In order to reduce the error of the effects,and improve the accuracy of integrated navigation,autoregressive process(AR)model is used to reduce the random error of MEMS sensor,and through extended Kalman filter to improve the precision of MEMS/GNSS integrated system,finally theoretical model was validated by the experimental data,which obtained a good effect.关键词
