摘要
随着卫星定位技术、计算机网络技术、数字通讯技术等新科技的深度结晶,以及GPS应用理论和误差综合原理的发展,CORS系统应运而生。但是在应用CORS系统进行地形图外业作业时,由于卫星信号遮挡和通讯信号的中断导致仪器初始化时间较长,甚至会出现失锁的现象。对整个数据的可靠性和精度产生影响。文章以南方S86T仪器为例,在辽宁省某重点工程的带状地形图中对CORS系统成果进行可靠性以及精度分析。
CORS network system rises in response to the deep integration of satellite positioning technology, computer network technology and digital communication technology and the development of GPS application theory and error comprehensive theory. However, in the field operation procedure of terrain map, the satellite initialization time for the signal occlusion and communication signal interruption maybe result in long instruments, or even the lock-lose, and will affect the reliability and accuracy of data. This paper takes the South $86T instrument as the example to analyze reliability and accuracy of CORS system in the band-shaped topographic maps of a key project in Liaoning Province.
