利用铷钟实现组合导航系统研究
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.
