基于BERNESE的GNSS连续站坐标时间序列解算策略研究
|
摘要
利用"陆态网络"260个连续站2012—2104年数据,在框架点选择、分区模式、联合平差策略方面对坐标时间序列的解算策略进行了优化。通过分析坐标时间序列稳定性及拟合速度,评价了BERNESE软件解算成果,并与其它软件和机构的解算结果进行了对比。结果表明,BERNESE解算策略在连续站时间序列解算工作中具有实用价值。
With the data of 260 GNSS continuous stations of the Crustal Movement Observation Network of China(CMONOC)from 2012 to 2014,using the BERENSE software,we optimized the solution strategy of coordinate time serial by frame selection,partition mode and joint adjustment strategy.BERNESE solution is evaluated and compared with that of other software and organization through analyzing the stability of coordinate time series and the fitting velocities.The result shows that solution strategy of BERNESE from this contribution has practical value.
