| 摘 要： | 文章基于现有40 GALILEO GSSs的布设方案,利用模拟数据,分析了我国及周边地区监测的SISE小于70 cm;假设我国周围某一GSS出现故障,其余GSSs监测SISE的精度,分析得出Kra或Lus发生故障时,局部区域SISE的监测超过70 cm,有必要增设GSS;以我国的IGS作为候选GSS,研究区域监测SISE的可靠性,分析得出URUM和XIAN联合40 GSSs,其监测的精度较高,可靠性较大,是GSS理想的候选站。 |

| Abstract: | Based on the existing scheme of 40 GSSs,the monitored SISE in China and its neighboring areas which is less than 70 cm are analyzed by making use of simulated data.By assuming that one GSS is out of work in an area near China and the SISE is monitored with others,it is concluded that if either Kra or Lus has wrong,the monitored SISE in local area is more than 70 cm,so it is necessary to add the GSS.By considering IGSs in China as the candidates of GSS,the reliability of the monitored SISE in China is analyzed,and it is concluded that the combination of URUM/XIAN and the 40 GSSs can produce higher accuracy and reliability in monitoring the SISE and both URUM and XIAN are perfect candidates for GSS. |
