摘要
为了提高处理GNSS数据时的解算精度,结合陆态网新疆地区28个连续观测站数据,重点分析在进行GLOBK平差时依据IGS站的选取不同而制定的3种解算策略对结果产生的影响。结果表明:进行陆态网新疆地区连续观测站网平差时,加入中国及周边17个IGS站进行约束就可使坐标和速度精度获得很大提升;当联合SOPAC提供的全球解H文件一起平差时,得到的测站坐标和速度的精度最高且明显提升。
In order to improve the accuracy of processing GNSS data,the paper comparatively analyzed the impact of three solution strategies made from the different selection of IGS stations on the accuracy in the GLOBK adjustment,based on the data of 28 continuously operated stations in Xinjiang area of CMONOC.Result showed that the accuracy of coordinates and velocity could be improve efficienctly with the constraint of 17 IGS stations of China and surrouding regions in the adjustment of continuously operated stations in Xinjiang area of CMONOC;moreover,the obtained coordinates and velocity of the stations would be highest with a great increase when adjusting combined with the H files by SOPAC.
