摘要
GPS测量技术是一种重要的现代测量技术,在各类测量活动中发挥着重要作用。笔者针对GPS测量的误差问题,从信号传播和信号接收两个方面进行分析,并提出了消除和消弱这些误差影响的方法和措施,主要方法有模型改正法和求差法。
GPS is one of the most important technique of modern measuring technology, playing an important role in meas urement activities. According to the problem of GPS measurement error, the author analysed the two aspects of GPS measurement error ：the signal transmission and reception, and presented two main methods and measures ：the model cor rection method and the difference method, to eliminate and weaken the influence of these errors.
