航海观测误差分布的研究

A Research on the Distribution of Error in Navigational Observation

本文提出一种新的航海观测随机误差分布的模型,称为航海综合分布NSD(a,b,c)。该误差分布除了能较好地反映出航海观测中经常出现的正态分布误差外,还能有效地体现航海观测中难以避免存在着的均匀分布和阶段分布误差,是一种综合性的误差分布。

A new model of random error distribution in the navigational observa- tion——Navigational Synthetical Distribution,NSD(a,b,c)is presented in this paper.The error distribution not only reflects the Normal Distribution that fre- quently appears in the navigational observation,but also reflects effectively the Even Distribution and the Period Distribution which are difficult to be avoided in the navigational observation.It is a synthetical error distribution.
