基于DSP的GPS定位解算算法研究与实现

摘要

采用TI公司的TMS320C6713DSP芯片实现了GPS接收机定位解算功能.利用该芯片实现GPS接收机各模块的调度,完成对时间观测量和导航电文的提取,进行卫星位置解算和用户位置解算以及对外接口.试验结果表明,根据该方案设计的GPS接收机工程样机可以准确地实现定位解算功能.%The navigation solution function of GPS receiver based on TMS320C6713DSP of TI Corporation is introduced. The TMS320C6713DSP was used to control each module of GPS receiver, extract observed time and navigation telegram to calculate the position of GPS satellites and the receiver, and provide external interface. The experiment shows that the navigation solution of GPS receiver works correctly.
