| 摘 要： | 基准站受构造运动与非线性因素的影响,如何构建高精度、现势性强的精细区域框架是位置服务与形变分析的的关键.笔者提出顾及基准站坐标动态特性与稳定性的区域框架构建方法.以我国西部与东部某城市的多年连续运行基准站数据为例进行试算比对,试验结果表明:该方法是可行的,较好地顾及了基准站的坐标特性与非线性影响,考虑了基准站的垂直运动规律,可构建高精度的区域基准,可发现区域基准的微动态变化.

| Abstract: | The tectonic movement and Nonlinear effection has the significant effection to the fiducial stations,The key of the location serveice and regional deformation analysis is that establish the regional terrestrial refference frame considering high precision and currency.This paper proposed a method of taking accout of the coordinate dynamic characteristic and stability.The western of China city was carried out for comparison,the experiments shows that it is feasible,the better to take into account of the coordinate dynamic characteristic,nonlinear variance and vertical motion,also can detect the micro-dynamic variation. |
