研究并给出了多源卫星测高数据基准统一的方法。利用经过精密预处理的测高卫星观测数据,计算得到了各测高系统之间的框架转换参数。同时,利用该转换参数结合交叉点平差技术建立了中国海域的平均海面高模型,并与KMS04、CLS01和WHU2000平均海面高模型进行比较,验证了多源卫星测高数据基准统一方法及其确定的框架转换关系的可靠性。
The methods for datum unification of multi-satellite altimetric data were studied and given, and the transfer parameters between several altimetric system were calculated from edited and corrected altimetric data. Fi- nally, a mean sea surface model of China Sea are established after data unification and crossover adjustment. Compared with CLS01, KMS04 and WHU2000 mean sea surface models, the validity and credibility of mean sea surface model of China sea and the transform method and parameters are verified.
