| 摘 要： | 为了限制GPS边长投影变形，可选择将边长归算至某一抵偿投影面上。基于抵偿投影原理，提出使控制网长度综合变形更小的最优抵偿投影面算法。通过实例验证，该方法在限制GPS边长投影变形方面优于其他方法。

| Abstract: | In order to control the projection deformation of GPS length,the length could be calculated to a certain compensation projecting plane.Based on the principle of compensation projection,the paper put forward the calculation of optimal compensation projecting plane,which could make the comprehensive deformation of controlling net length smaller.By verification of examples,this method in controlling of GPS length projection deformation was better than other methods. |
