| 摘 要： | 本文探讨一种在做G PS平面控制测量时，既削弱了当地的投影变形，其成果又与国家坐标系坐标成果几乎一致的一种方法，即分网平差法，通过外网将国家坐标系引入测区，在内网再进行投影变形改正，对该方法进行了阐述，并结合工程实例对此方法进行了验证，对成果进行了详细分析与处理，为相似工程提供依据和参考。

| Abstract: | T his paper studies a kind of doing GPS horizontal control survey ,already weakened local projection deformation ,a method of the result is almost consistent with the national coordinate system results ,namely network adjustment method ,the national coordi-nate system is introduced into measurement area through network ,and projection deforma-tion correction is done .From the theory to the practice ,the method is discussed .Combined with the engineering practice ,this method is verified ,and the results are analyzed and pro-cessed .Similar projects for the future provide a basis and reference . |
