通信定位系统中定位解算

The Realization of Positioning Solution in Communication Orientation System

伪码测距的高动态目标定位是基于直序扩频系统的到达时间(TOA)测量原理,为满足高动态用户的需求,根据一定实测经验数据,建立基于高度的大气层延迟模型,再结合定位接收机与地面引导站的仰角进行伪距的大气层误差修正,提出基于DSP的伪距定位解算实现方法,结果表明该方法在定位解算速度以及定位接收机小型化方面将会有良好应用前景和社会效益。

The theory of spread spectrum TOA utilizing in the high dynamic positioning system is introduced. In order to adapt the high dynamic user, a model of aerosphere delay based on highness is build on the basis of the mensurated experience data, and the elevation between the position system and the ground introductory system is utilized to modify the aerosphere error of the pseudo noise code measuring distance. A method of realizing position-solution based on DSP is presented, the results show that the method have a well future and social benefits in the solution efficiency and the system miniaturization.
