Abstract:
An expression for the potential accuracy of the extended state vector estimation multiposition radio systems, including along with the coordinates of the radio source coming from the navigation system coordinates the collection points. It is shown that the use of the implementation of angle and difference-ranging multi-position radio surplus expanded composition of the state vector can improve the accuracy of determining the coordinates of radiation source and receiving points. For multiposition radio minimum content of reducing errors of survey is not possible, the maximum likelihood estimator does not allow the assessment to clarify the coordinates of collection points and ellipses scattering coordinate reception centers coincide with the circles that characterize the positioning accuracy of collection points.
