摘要
讨论了检验GPS观测值误差分布的重要性,提出了对GPS观测值误差分布检验的基本方法和公式。通过一个检验的实际算例,表明GPS RTK观测数据的概率密度函数不一定服从正态分布,有必要进一步研究各种状况下GNSS观测值的误差分布。
In this paper, the importance to study the error dis- tribution of GPS observations is discussed, the essential meth- ods and formulas for the error distribution test of GPS observa- tions are then put forward. It is indicated that the GPS observa- tions do not always obey the normal distribution through the ex- amination of an actual example. It is necessary to further the study of GNSS observation ＇s error distribution under each dif- ferent conditions.
