摘要
以GPS为代表的卫星导航系统受定位精度的约束,需外加在地面的伪卫星提供辅助定位信息,确保定位精度。本文提出了基于软件无线电思想的伪卫星接收机数字平台设计方案,给出了3种硬件实现方式:基于DSP的数字平台实现;基于FP-GA的数字平台实现;基于ACM的数字平台实现。同时针对这3种实现方式从硬件资源、算法实现两个角度进行了比较。
The satellite navigation systems such as GPS are restrained by the precision of orienting,PL,which offer the auxiliary information of orienting ,guarantee to the precision of orienting. This text proposes the design on digital platform of PL receiver. And it provides three ways of realizing ;the digital platform based on DSP ;the digital platform based on FPGA; the digital platform based on ACM. This text also compares resources of the hardware and the algorithm to these three ways of realization.
