BDS精密相对定位精度的GAMIT分析
|
摘要
为了验证GAMIT用于BDS精密相对定位的可靠性与精度,该文以BDS短基线和长基线实测数据,基于GAMIT软件的不同解算策略进行BDS精密相对定位实验。由实验结果可知,GAMIT用于BDS短基线解算,相对于GPS在水平方向基线分量差值优于3mm,在高程方向基线分量差值优于3mm;GAMIT用于BDS长基线解算,相对于GPS在水平方向的基线分量差值优于6mm,在高程方向基线分量差值优于1.3cm。研究结果表明,GAMIT可用于BDS的精密定位解算且精度较高。
In order to verify the reliability and accuracy of GAMIT for the precision relative positioning of BeiDou navigation satellite system(BDS),this paper used BDS short baseline and long baseline measured data,based on GAMIT software for BDS precision relative positioning experiments.From the experimental results,it was known that GAMIT used for BDS short baseline solution,the baseline component difference was better than 3 mm in the horizontal direction compared with GPS,and the baseline component difference was better than 3 mm in the elevation direction.GAMIT used for BDS long baseline solution,relative to GPS,the baseline component in the horizontal direction was better than 6 mm,and the baseline component in the elevation direction was better than 1.3 cm.The research results showed that GAMIT could used for the precise positioning solution of BDS with high precision.
