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。Using the Corssh data in the same sync segment of T/P satellite, Jason-1 and Jason-2 satellites, the altimetry system errors of different altimetry satellites in the Yellow Sea synchronized segment are studied to get system errors of 0. 074m and 0. 075m in the rail lifting and rail descending between T/P satellite and Jason- 1 satellite, as well as the system errors of 0. 066m and 0. 076m in the rail lifting and rail descending between Jason-1 and Jason-2 satellites.By calculating system errors of data from multigenerational satellites,the reliability of data fusion is enhanced.
