GPS卫星定位系统设计中几个问题的探讨

Study on GPS designing

结合当前GPS的发展趋势,简要介绍了GPS定位技术的特点,并从理论和实践两方面就GPS在设计中可能出现的几个问题进行了深入探讨,主要包括:伪距测量误差的纠正、GPS接收板的数据格式以及GPS系统设计中的数据转换等.从GPS定位原理出发,论述了伪距测量误差产生的原因及解决的方法,结合GPS卫星定位技术的具体应用,提出了两种可行的设计方案,对GPS卫星定位设备及跟踪系统的设计、开发具有一定的实际意义.

Associating with developing trend of GPS nowadays, the characters of GPS location technology is simply expounded. Several problems about GPS satellitelocation system probably appearing in designing based on principle and experience are discussed deeply,including,GPS distance error adjusting?Datum standard of GPS receivers and datum transforming in GPS system designing, etc. The reasons and solution methods of error according to GPS location theory are set forth, and associating with the concrete applications of GPS, putting forward two designing project. It will have practical sense to the designing and exploring of GPS satellite location system and tracking system.
