摘要
介绍了目前生产中 GPS高程应用的几种方法 ,并说明了它们的原理及应用条件。结合山区长输气管线的自然地理状况 ,将 GPS高程计算结果与传统电磁波测距三角高程测量的结果进行了对比 ,摸索出适合山区线路测量 GPS高程的计算方法。
Some methods of GPS leveling,including their principles and necessary conditions are given in this paper.Regarding to the geographical conditions of long transit gas pipeline in mountain areas,this paper compares GPS leveling with traditional EDM to seek a proper method for such works in mountain areas.
