摘　　要：为了研制高动态GPS软件接收机,本文利用TMS320C6713,GP2010和GP2021设计了软件接收机硬件平台。基于所选择的硬件平台,对捕获、码跟踪、载波跟踪算法的选择及其参数与接收机动态性能的关系进行分析。实验结果表明:理论分析和实验结果是吻合的,所研制的GPS接收机在速度12 km/s、加速度为10 g,加加速度为10 g/s、数据更新率为10 Hz的情况下,定位精度可达15m。To develop a high-dynamic GPS receiver with independent intellectual property,the hardware platform of the software receiver is designed by using TMS320C6713,GP2010 and GP2021.Based on the chose hardware platform,the choosing of the acquisition,the code tracking and the carrier tracking algorithms,and the relation between the parameters and dynamic performance of GPS receiver are studied.Experimental results indicate that it is uniform with the theoretical analysis,and the position accuracy of the GPS receiver can reach 15 m under the conditions,i.e.,the speed,acceleration,jerk and data rate are 12 km/s,10 g, 10 g/s and 10 Hz.
