摘要: 讨论了相关观测值与非相关观测值的多余观测分量值域问题;论证了相关观测值的多余观测分量与内可靠性指标的不一致性;进一步研究了可靠性指标的应用问题,认为当观测值的复相关系数不同时,应同时考虑内、外可靠性指标;最后,以GPS准动态测量为例作了分析。

Abstract: In this paper, the range of the redundant observation component for correlated and uncorrelated observations is discussed, and the difference between the redundant observation component and the internal reliability is proved. Then, the further study on using the problem of reliability indicators is taken, and when one multiple correlation coefficient is different from another for correlated observations. Their internal and external reliability indicators should be simultaneously considered. Finally, an actual example of GPS stop and go positioning is analyzed.
