| 摘 要： | 基于北斗双星定位系统(RDSS)采用有源定位体制存在一定的局限性，在接收机能够测量用户至卫星的伪距信号以及在气压高度表辅助的前提下，提出了利用铷钟作为接收机内部时钟的RDSS与捷联惯导进行伪距组合的模型，建立其卡尔曼滤波的状态方程与量测方程．仿真结果表明，组合后的导航系统具有输出导航参数误差小的特点．

| Abstract: | Bei-dou double-star positioning system (RDSS) adopts an active positioning system, so it has certain shortcomings. In order to overcome those limitations, and on the premise that the receiver can measure the pseudo-range between the user and satellite and with the help of barometer, this paper put forward the pseudo-range integration model of RDSS and the strap-down inertial navigation system with high precision clock, rubidium clock being the internal clock of the RDSS receiver. The state equations and measurement equations were built up for Kalman filtering. The simulation shows that the output navigation parameters of the integrated system have the characteristic of low error. |
