摘　　要：GPS高程拟合在一定条件下,可得出令人满意的正常高成果。我们采用合适的数学模型,加上适当的技术措施,在长江三峡地区开展GPS高程拟合应用研究,结果表明拟合高程(内、外)符合精度指标达到甚至超过四等水准的要求。The approving result could be got with GPS height simulation at special condition. Several mathematical models and observation technology were discussed in the paper. The precision of GPS height simulation in Three Gorges region was up to scratch and exceeded the standard of the State fourth level.
