摘　　要：通过采用数值拟合法对一实测ＧＰＳ网点正常高的求解，详细讨论了已知水准点数量和在网中的分布情况对正常高求解精度的影响。并在此基础上，提出了一种已知水准点可靠性检验的方法——分组拟合加统计检验的方法，经实验验证，该方法是可行的。The number of the known level points and the distribution in network which had an impact on the solving precision of the normal height was discussed by adoptinga method of the numerical value match to solve the normal height of GPS network points which was actually surveyed.On the basis of above,a method of the reliable test of the known level points (i.e. a method of grouping match with the addition of statistics test) was recommended.The method was a feasiable one with a certain practical value as a result of experiment.
