| 摘 要： | 在GPS载波定位中双差观测值权的确定较为重要,本文在简要介绍了两种常规定权方法之后首次提出了“高度角定权法”,并以某大型水电站的实测数据分析了三种定权方法对基线坐标解算结果精度的影响,数据结果清楚地表明本文提出的“高度角定权”能有效地提高基线坐标解算结果的精度。

| Abstract: | The weight of the double difference observation in GPS carrier phase positioning is important.Two common methods of the weight determination are briefly introduced and the weight determination of the altitude angle is firstly brought forward in the paper.Based on the surveying data of some large water and electricity station,the influence on the baseline coordinate calculation precision is analyzed,and the data analysis results indicate that the weight determination of the altitude angle can effectively improve the precision of baseline coordinates. |
