摘要
GPS技术具有全天候,抗干扰,精度高,实时性强等优点,是目前最理想的空间定位技术.它给测绘和3S行业带来了一场新的技术革命,大大提高了工作效率,减轻了劳动强度,提高了定位精度.本文以广西沿海某城市布测的一个D级GPS控制网为例,着重讨论了网的布设方案和结果精度,并进行了精度评价和分析,阐明了GPS技术的优越性,总结了提高GPS定位精度的方法.
With merits of all - weather , anti - jamming , high - precision and instant, GPb is the most perfect spatial orientation technology presently. GPS brought a new technology revolution to the fields of mapping and 3S, with the result of improved work efficiency, lightened work intension, advanced orientation precision. This paper took a D grade GPS control web located in a coastal city of Guangxi as an example, discussed the distribution project and result precision of the web, made precision evaluation and analysis, clarified the advantages of GPS and finally concluded the methods for advancing orientation precision.
