摘　　要：针对卫星导航(GNSS)接收机调试过程环路参数多、不易观测等问题,设计了基带和定位的软件调试监测系统。通过在FPGA编写串口程序,实现通道数据向PC机实时传输;利用自研软件,实现环路和定位数据的监控、记录保存和功能回放。测试结果表明,该系统能较好反应环路数据和定位性能的好坏,通过回放分析能快速查找问题,达到辅助硬件调试和数据监测的目的。In the process of developing and debugging GNSS receiver,there are too many loop parameters to observe and other problems to solve.Then a software system of base band and positioning helping for debugging,inspecting ＆ testing was designed.Through writing high-speed COM port program,the data transmitting real-time from FPGA to PC was realized.Through designing software program on PC,the GNSS data＇ inspecting,testing,display,saving and review was realized.The testing results indicate that the software system can inspect the GNSS data effectively,we can find some problems quickly by using data review,and then the purpose to assistant hardware program debugging and data inspecting can be achieved.
