摘　　要：对于很多望远镜系统来说,系统本身需要准确的时间、经纬度等GPS信息,为了满足某望远镜系统的应用,设计利用C8051F120高速单片机及U-blox公司的GPS接收机设计完成了此GPS系统;重点介绍了GPS数据的提取、与望远镜系统的通信以及GPS信息在望远镜系统上的应用,通过提高系统工作频率、数据信息的压缩处理、秒信号触发单片机外部中断等方式,提高了GPS系统的时间精度;该系统已经在两个不同望远镜系统中得到应用,实验结果表明可以满足不同系统的通信协议,在实际运行中稳定可靠,能够达到望远镜系统所要求的时间精度。According to many telescope systems, they need exact time, longitude, latitude and so on. In order to satisfied one telescope system, the GPS system has been designed based on high--speed MCU C8051F120 and GPS receiver of U--blox company. Picking up GPS data, communicating with telescope system and application of GPS data in telescope are particular introduced. Through improving system working frequency, compressing data and MCU＇s external interrupt means, the GPS system has a precise time. Two different telescope sys- tems have used the GPS system. The practice proved that it can satisfy double communication information of differen systems. Practically, the GPS system is working well and can satisfy the precise time of telescope systems.
