| 摘 要： | 利用T/P卫星、Jason-1卫星以及Jason-2卫星同步段的Corssh数据,研究了黄海海域同步段不同测高卫星的测高系统差,得到了T/P卫星与Jason-1卫星间升轨与降轨系统差为0.074m与0.075m,Jason-1卫星与Jason-2卫星间升轨与降轨系统差为0.066m与0.076m。通过计算多代卫星数据的系统误差,提高了融合数据成果的可靠性。

| Abstract: | Using the Corssh data in the same sync segment of T / P satellite,Jason- 1.and Jason- 2.satellites,thealtimetry system errors of different altimetry satellites in the Yellow Sea synchronized segment are studied to getsystem errors of 0.07 4.m and 0.07 5.m in the rail lifting and rail descending between T / P satellite and Jason- 1.satellite,as well as the system errors of 0.06 6.m and 0.07 6.m in the rail lifting and rail descending betweenJason- 1.and Jason- 2.satellites.By calculating system errors of data from multigenerational satellites,the reliabilityof data fusion is enhanced. |
