Observation redundancy influence over parameter precision

Abstract

the measures of sensitivity of the partial redundancy of the observation and of the precision of the parameters are presented. The concepts of internal and external reliability are shown. Some implications and applicabilities are also discussed. The possibility of these measures supply resources for the optimization of geodetic networks is presented by means of an application. The results lead to a safe decision concerning cast out observations, which do not cooperate with parameter precision. Keywords: Redundancy sensitivity; observation redundancy; Parameters precision; optimization of geodetic network.
