具有抵偿面的GPS基线向量网任意带高斯投影模型研究

Research on the Arbitrary Zone Gauss Projection Model with Compensation of GPS Vector Line Network

通过GPS技术获取的空间基线向量和坐标信息是建立在WGS-84坐标系下的,无法直接应用于工程实际。因此使用GPS基线向量网必须将其从WGS-84坐标系转换到测区的平面坐标系统中,这就需要构造一个具有抵偿面的任意带高斯投影模型,来控制和减小边长投影变形。

The space baseline vectors and coordinates information obtained through GPS is built on the WGS -84 coordinates, which cannot be directly applied in engineering practice .Therefore, the GPS baseline vector network information must be transformed from WGS-84 coordinates to the plane coordinates of surveying area for use .So constructing an arbitrary zone Gauss projection model with Compensation to control and reduce length projection deformation is imperative .
