| 摘 要： | 介绍了双星定位系统（RDSS）的局限性，提出了利用高精度时钟，即铷钟作为接收机内部时钟，如接收机能够测量用户至卫星的伪距，在气压高度表的辅助下，双星定位系统可以与捷联惯导进行有效的伪距组合。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，为发展双星定位系统提出了一条新的思路。

| Abstract: | On the basis of introducing the limitations of the double-star positioning system,the precision rubidium clock was put forward to be the internal clock of the RDSS receiver.If the receiver could measure the pseudo-ranges from the user to the satellites,with the help of barometer,the RDSS could be integrated with the strap-down inertial navigation system based on pseudo-range.The simulation result shows that the output navigation parameters of the integrated sys-tem have the characteristic of low error,which offers one new way to develop our country's RDSS. |
