Research on Redundant Observation Components and Reliability Measures for Correlated Observations

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.
