摘要: 在对广域差分GPS定位算法精度分析的基础上,建立了通用GPS系统运算平台,构造了浮点类型,并提出了DSP运行环境中的高精度函数算法,完成了对广域差分GPS定位算法的优化,编制了基于通用DSP系统的广域差分GPS定位算法软件,成功研制了广域差分用户接收机系统。Abstract: In the research of WADGPS receiver, authors built general proposal GPS operational platform using TMS320C32 32-bit DSP chip, constructed double-length floating data type and high precision mathematic functions. Base on these works, the work of algorithm optimized is done. This paper also shows the flow of the DSP firmware and the running results.
