| 摘 要： | 针对当前常用的导航、定姿方法存在的不足,提出了一种采用单天线GPS、磁强计和加速度计的组合导航、定姿方法.以常见的匀加速模型作为系统方程,以GPS输出的位置和速度作为观测量,设计了卡尔曼滤波器,获得更精确的载体速度、位置和加速度信息.在获得加速度估值之后,根据地磁场和载体比力在载体坐标系和导航坐标系的投影关系构造姿态矩...

| Abstract: | This paper presents a navigation and attitude determination approach based on the GPS/magnetometer/accelerometer against the shortages of the current navigation and attitude determination methods.To obtain more accurate location,velocity and acceleration informations,the Kalman filter was designed with the uniform acceleration model as the system equations and the location and velocity informations of the GPS as the observed values.After estimating the acceleration,the attitude matrix,from which the attitud... |
