Abstract

The factors that cause errors in navigation information during the operation of satellite navigation systems are considered. The errors due to multi-beam interference are investigated. Methods for errors compensating of a satellite navigation system, which make it possible to compensate the influence of disturbing factors, in particular, errors caused by radio signals reflected from obstacles, are presented. It is proposed to build models of reflected signals by means of evolutionary algorithms. In the process of the satellite navigation system functioning, a systematic component model of the reflected signal with parametric identification is used. Keywords satellite navigation system, multiple-beam interference, error compensation, algorithms for building models, systematic component of the error, parametric identification
