GPS定位试验及提高定位精度的方法研究

对3种不同的4个GPS接收机进行了定位试验,主要包括单点静态定位试验和动态测量面积的试验.经过一系列的数据分析和处理,分别得到了3种典型的GPS接收机在这2种试验条件下的定位精度及排序,并且采用算术平均值法对最佳测量次数进行了研究,提高了GPS单点静态定位的精度.提出了在数据处理中加入控制点的方法,提高了GPS动态测量面积的定位精度.

Study on GPS orientation experiment and method of improving location precision

Several orientation experiments with three different types of four GPS receivers were conducted which included single point orientation experiment and dynamic area measurement experiment. After a series of data analysis and treatment, location precision and the sequence of these GPS receivers under two experimental conditions were separately gained. By means of arithmetical averaging method, the optimum number of measurements was derived and the precision of GPS single point orientation was improved. Furthermore, a method of adding control point during data treatment was advanced and location precision of GPS dynamic area measurement was raised.
