The nautical system’s conditions in high latitudes (in the area of Talakan and Igarka airfields) assisted by GLONASS, GPS and combined system GLONASS/GPS have been examined through semirealistic simulation. Nautical session’s conditions are characterized by horizontal (HDOP) and vertical (VDOP) geometrical factors’ values in specified areas of terrain. Researches using the firmware complex within the satellite navigation systems signal simulator CH-3803M and the aeronautical receiver CH-4312, interlinked by bus ARINC-429 with personal сomputer have been con-ducted. Particularities of using the simulator and receiver CH-4312 for carrying out semirealistic experiments have been shown. By comparing these results with the results of realistic experiments the validity of semirealistic modelling has been estimated. The accuracy of receiver’s CH-4312 position determination when operated by GLONASS, GPS and combined mode for Talakan and Igarka areas have been examined.

Based on the usage of LabView’s developed program of orbital motion modeling and the choice of satellite’s working constellation, the methodology of building-up the fields of potential accuracy GLONASS in the given airspace has been proposed. The methods are based on the estimation of horizontal (HDOP) and vertical (VDOP) geometric factors’ values in points chosen with given latitude and longitude discontinuity in the airspace which is being studied. By relevant error handling the areas where the values of HDOP and VDOP lay within given range and their cartographic matching are selected. Expressions for geometric factors calculation are listed. By comparing the data of real experiments with semireal-istic simulation which have been conducted with the aeronautical receiver CH-4312 and the simulator CH-3803M, the validity of math model and the results’ accuracy have been evaluated. Investigations of geometric factors’ change in the initial and finishing points of flight route and also during the flight Irkutsk-Moscow have been conducted. As an example the fields of accuracy GLONASS in horizontal and vertical surfaces for the airspace between Irkutsk and Moscow have been built for such points in time that match the aircraft’s take off in Irkutsk and its landing in Moscow.

The article describes the models for assessing aircraft accident risk due to aircraft coordinate information errors at the controller’s air situation display. The models allow to justify safety requirements on aircraft coordinates display accuracy or to assess the current aircraft accident risk by analyzing observed intervals between aircraft and parameters of the surveillance system.

The dependence of the accuracy and availability of aircraft location on final approach on signals of GLONASS with the certain satellites elevation angle is determined. Estimation of the accuracy and accessibility of the aircraft loca-tion was calculated for angles of elevation of the satellites within the specified range for the various aircraft location.
