一种区域定位系统的概念

A Regional Positioning System Concept

区域定位系统是一种与GPS兼容的地基导航系统，可以完成轨道飞行器乃至弹道试验的定位和定轨任务。区域定位系统由若干地基导航发射台（也可增加一、二个天基导航台）网和卫星载接收机组成。其定位精度估计在100m以内，如地面导航台网与GPS差分导航台结合起来，将会发挥更大作用。

The Regional Positioning System (RPS) is a ground - based navigation system compatible with GPS, which can be able to complete position and orbit determination of spacecrafts as well as trajectory test. RPS consists of several gronnd based navigation transmitting stations (perhaps a few space - based navigation stations added) and on - board receivers.Its position accuracy is batter than 100m. Should the ground navigation station network is combined with diffrential GPS navigation stations, RPS wonld give full play to more important effect.
