摘　　要：讨论了长距离精密GPS控制网的特点,通过设置不同的精密测距基线,计算相应GPS控制网的精度,从而掌握连接方式、重复基线、精密测距仪基线对GPS网精度影响的规律,解决了长距离精密工程GPS网的建立方法。The feature of GPS network with long distance is discussed. The precision of GPS network is computed corresponding to different precise distance baseline, so that some problems are hold, such as connect type, repeat baseline and influence rule of distance baseline to the precision of GPS control network, and the method of establishing GPS network with long dis tance is resolved.
