State of the art

Known work of the company Thales (France), "Procedures for guiding the aircraft at the approach stage and the corresponding ground beacon." Patent No.US 7,218,278 B1 dated 05/15/2007

The invention relates to a procedure for guidance of an aircraft on the runway in the phase of an inaccurate approach. At the same time on board the aircraft is provided:

- receiving information about a given approach path contained in the message emanating from the ground beacon in the format of the ground based augmentation system (GBAS);

- reception from the ground-based augmentation system (SBAS) through geostationary satellites of corrective information for SNA signals;

- calculating the corrected position based on the signals of the SNA and corrective information;

- calculating the vertical and horizontal deviations of the aircraft from a given approach path based on the adjusted position and information about a given approach path.

Thus, for guidance of the aircraft, combined information is used - SBAS differential corrections and information about the final approach area from the ground beacon in GBAS format, which does not transmit differential corrections. At the same time, signals from the global satellite navigation system (GNSS), SBAS are received on the ground beacon and trajectory control is organized.

This method does not consider solutions to air traffic control problems.

A known patent of the Russian Federation for utility model No. 49297 G05D 1/00 of July 6, 2005, authors Evgenova A.V., Konstantinova V.I. and others. "Information and control complex of aircraft." This information-control system allows for effective management in extreme flight conditions, creating an information-control field that allows the pilot to simultaneously see the main flight parameters, off-cabin conditions and dangerous conditions, forming control actions appropriate to the situation when flying on high-precision maneuvering modes in low-altitude flights above difficult terrain, approach and landing on a low-equipped airfield in difficult weather conditions.

However, this information management complex does not provide automated navigation functions with the flight control tasks performed by the air traffic control service using advanced modern methods based on the global CNS / ATM system.

Known RF patent for the invention No. 2239846 G01S 13/91 from 07/15/2002, the authors Safyan D.A., Safyan A.D., Konstantinova A.I. "Air traffic control system in the near zone of the airport."

The invention relates to systems for supervisory control and air traffic control in the near zone of the airport. The system includes a grouping of navigation satellites, on-board equipment, determining the current coordinates of the aircraft, ground-based equipment of the air traffic control system, and an airport radar station. Dispatcher using a combined image containing the graphic design of the runway and the lines of the calculated aircraft descent trajectory, board number, aircraft silhouette and current trajectory, as well as graphic and service information containing corridors of permissible deviations in heading and flight altitude. The air traffic control system is extremely visual, operational, reduces the psychophysiological load of the air traffic controller. However, the current flight coordinates are determined without differential correction, which reduces accuracy.

In this paper, we consider only one transmission line of motion parameters and aircraft position without the use of automatic dependent observation.

Known patent for the invention No. 2343530C1 from 07.17.2007, the authors Urlichich Yu.M., Moiseenko V.P., Zakharova N.Yu. “The system of control and prevention of unauthorized flights of small aircraft in the airspace of large cities and critical facilities,” which was adopted by the authors as a prototype.

The invention relates to aircraft instrumentation for small aircraft and extends the functionality of an on-board automatic control system (ACS) in the case of exceeding the limit value during unauthorized intervention of controlled parameters and the inclusion of an unmanned self-propelled guns to withdraw from a critical position or force landing when using high-precision control based on signals local differential subsystem. In this case, a radio line for operational dispatch control and management is used.

In this work, an additional circuit of automated high-precision control is used only to prevent terrorist attacks or in case of failed board conditions during operational dispatch control over radio communications.

In accordance with the technical solution, a wide range of radio dispatch voice communications and land-to-ground communications were introduced into the ground and airborne parts of the complex.

Thus, the hallmark of the proposed aircraft navigation system based on the on-board multifunctional system using satellite technology (SNA, LKS) from the above known systems, incl. The prototype is that it performs all modes of automated navigation with the simultaneous solution of air traffic control tasks, based on the modes of a promising global system for the communication, navigation, surveillance and air traffic management of CNS / ATM (CNS / ATM) and is based on the use of exclusively domestic systems development and production.

Implementation of the observation mode in the ATC-ATC with indication of information on the ARMD screen from three independent sources at the choice of the dispatcher and solves the following tasks:

- control and management of aircraft keeping specified routes (trajectories) and flight levels;

- prevention of dangerous proximity and collisions of aircraft in flight and on the ground with obstacles by controlling their separation and separation at safe intervals in accordance with the rules of air traffic control.

Figure 2 shows an example of an information frame of the ARMD screen with registration of marks, parameters and identifiers of aircraft against a map of the area with concentric circles of a range of 24 from the airport located in the area of responsibility of the air traffic controller 23. The information frame shown in figure 2 contains: LA 21 mark (□ ), LA 22 parameters (identifier, for example TU 154M), altitude, azimuth - A, range - D) and allows the dispatcher to visually, conveniently read, evaluate, make a decision and monitor the air wounds.
