Model assessment of the correlation influence coordinates error on the accuracy of determining relative position with ships maneuvering

Increase the accuracy of relative position when using GPS in standard mode can be provided conformed dimensions under a single constellation of navigation satellites specific GPS, due to correlation of errors of coordinate, close to 1. The aim of this work is to evaluate the impact of correlation of errors of coordinate, jointly maneuvering the ships on the accuracy of determining the relative position and the possibility of increasing the accuracy of determining the relative position together maneuvering the ships using AIS.
