一种新型GPS实时定位系统的设计

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。

Design of a New Real-time Positioning System Based on GPS

To a wide range of applications of the arget 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. To improve the reliability, a GPS backup module is designed. 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.
