| 摘 要： | 全球定位系统(GPS)技术己经在许多领域得到广泛的应用,由于GPS定位得到的观测成果通常是世界大地坐标系统WGS-84中的坐标或坐标差,但在实际应用中上需要的往往是地面点在国家坐标系或地方独立坐标系中的坐标.确立坐标系统转换模型并分析此模型的精度,根据至少3个公共点的两套大地坐标利用最小二乘法原理求出转换参数.本文以W...

| Abstract: | The global positioning system(GPS) technology is wildly used in many fields.The GPS observation achievements are usually the geodetic coordinate or its subtraction of system WGS-84,but what we need is the coordinate of ground points which in national coordinate system or local independent coordinate system.Establish Coordinate system transformation model and analyze the precision of the model,according to at least three public points of two sets of geodetic coordinates by using least-square method to solve ... |
