Method for Assessment of Integrity of High-Precision Navigational Sightings

. The article presents a method for assessing the integrity of high-precision navigation sightings of the consumer. The issues of the integrity of navigation, the factors affecting the accuracy of navigation are considered. The developed methodology uses methods of autonomous control of the integrity of the consumer, information on operational intrasystem GLONASS/GPS integrity monitoring, and the results of operational integrity monitoring from functional additions. On the basis of the algorithm of high-precision consumer navigation and corrective information from the augmentation and monitoring system (SAM) of navigational fields of global navigation satellite systems, experimental evaluations of the proposed methodology were carried out. The result of application of the developed methodology is an increase in the reliability of high-precision navigation sightings, the establishment of the fact of switching to the high-precision navigation mode, and reducing the time of notification of the consumer about violation of navigation integrity.
