摘　　要：针对目标飞行器定位的广泛应用,提出了一种基于单片机和CPLD硬件平台的新型GPS实时定位系统,该系统由目标发射机和GPS接收机组成。两部分实现通用化设计,均由GPS模块、中控模块、无线射频模块、电源管理模块等模块组成。系统工作时,目标发射机通过无线串口发送GPS数据,地面GPS接收机完成数据的采集与编帧并经FT245接口回传PC终端以实时监测和事后分析。测试结果表明:该系统能够实时地、精确地完成不同环境下多种飞行器的定位。To a wide range of applications of the target aircraft positioning,a new real-time GPS positioning system that designed based on the hardware platform of MCU and CPLD is proposed. The system consists of a transmitter onboard and a GPS receiver component. Two parts are universally designed,and both of them consisted of the GPS module,the control module,a wireless RF module,power module and other modules. When working,Airborne GPS transmitter sends data via a wireless serial port,Ground GPS receiver completes the data collection and framing and then returned data to PC terminal via the interface of FT245 for Real-time monitoring and post-mortem analysis. Test results shows that the system is capable of real-time,accurately locating aircrafts within a variety of different environments.
