Self location Method of Regional Positioning System in Engineering Survey Application

摘要:

提出了一种系统自定位方法.该方法采用控制点坐标进行约束，按照非线性最小二乘的LevenbergMarquardt算法求解系统自定位参数.以双发射站为例，给出了新的系统自定位参数的解算模型.通过试验证明此方法是可行的，解算模型是正确有效的，其系统自定位精度完全能够满足工程测量的要求.

Abstract:

In this paper, a selflocation method is proposed. Constrained by the coordinates of control points, the parameters of selflocation are solved by LevenbergMarquardt algorithm which is a nonlinear least square method. Taking the example of double transmitters, the solution model of the selflocation method is introduced in detail. By the experiment, it is verified that the selflocation method is feasible, the solution model is effective and the accuracy of selflocation can meet the requirements of engineering survey.
