Description

The utility model relates to radio communications technology, in particular to radio signal relay devices for increasing communication range deployed on aircraft.

The closest in purpose and most of the essential features is the "Helicopter Unified Relay Complex" (VUKR) [1], which is adopted as a prototype.

VUKR contains relay equipment located in two containers, interconnected by a cable network, connected to a regular helicopter power supply system, and three transceiver antennas.

The relay equipment includes: an automatic relay device, an RF channel multiplexer, an integrated control panel, and MV-DMV radio stations.

VUKR operates in an automatic maintenance-free mode and provides two independent simplex channels for relaying open or closed telephone or telecode information in the MV-UHF range in the air-to-air, ground-to-air, and ground-to-earth communication directions, allowing to increase the communication range up to 350 km.

A feature of this complex is the placement of relay equipment in two easily removable portable containers, the design of which ensures their transfer through the doors and hatches of the helicopter, quick installation and fastening inside the fuselage of the helicopter using standard mooring units, and the ability to install transceiver antennas on the carrier helicopter without its constructive improvements.

At present, fundamentally new radio communication systems have appeared that provide high noise immunity and information transfer speed. Such systems include the currently developed domestic multifunctional integrated communication, navigation and recognition system (MISSNO) [2]. From the consumer's point of view, MISSNO is a collection of information exchange networks, including digital telephone and telecode communication. Using the system’s ability to determine the propagation time of signals, MISSNO subscribers get the opportunity

solve navigation problems based on the rangefinder (pseudo-rangefinder) method. The combination of connected and navigation functions makes it possible to solve the problem of identification (recognition) in the system based on the navigation-connected method.

MISSNO's technical basis is comprised of microwave terminals installed at subscribers, which are functionally complete devices that implement all the functions of transmitting, receiving, processing, and relaying telecode and voice information.

The terminal includes a radio frequency unit (receiver, transmitter, frequency synthesizers) and an information processing unit (signal processor, channel processor, information coding and protection modules, data processing processor, speech-converting device).

Broadband pulse signals of the terminals, the parameters of which vary according to the pseudo-random law, make it impossible to set impact interference. A wide band of radiated frequencies protects against obstruction.

The terminals of the corresponding embodiment can be installed both for aviation and ground subscribers MISSNO.

The MISSNO range radio signals propagate within the line of sight, so the task of increasing the communication range, especially for terrestrial system subscribers, becomes urgent.

The main technical task, which this utility model is aimed at, is the creation of a highly mobile dual-band unified relay complex (DVUKR), which provides relaying information not only in MV-UHF, but also in the microwave range MISSNO, which can be quickly installed in the field to any carrier helicopter (for example, a widespread Mi-8 type helicopter), without its structural development.

The specified technical result is achieved by the fact that in a helicopter relay complex containing relay equipment located in two containers interconnected by a cable network, connected to the helicopter power supply system, having articulation nodes together, as well as fasteners to the regular mooring nodes of the helicopter, and three transceiver antennas mounted on the fuselage of a helicopter, high frequency

the cables of which are passed through the fuselage sheathing through the standard openings and connected to the high-frequency connectors on the containers, the terminal also includes a multi-function integrated communication, navigation and recognition system, configured to relay the received information in the microwave range, located in the third container connected to the helicopter power supply system having fastening elements to the regular mooring units of the helicopter, and a fourth transceiver antenna, s mounting on the fuselage of the helicopter, the high frequency cable is passed through the skin of the fuselage through staffing hole and is connected to a high frequency connector on the third container.

The DVUKR, possessing all the advantages of the prototype, is additionally able to provide for the exchange of a helicopter carrier, the exchange of telecode and voice information and its relaying with high noise immunity and speed in the microwave band MISSNO in automatic unattended mode.

Structurally, the DVUKR consists of two independently operating relay complexes: the MV-DMV range relay complex located in two easily removable portable containers and the MISSNO range relay complex, located in the third easily removable portable container, made similarly to the two previous ones, on a carrier helicopter. Four transceiver antennas of the complex (three MV-DMV and one MISSNO band) are attached to the fuselage of the carrier helicopter without its structural development.

The work of the DVUKR, in terms of relaying information in the MV-UHF range, is no different from the work of the prototype.

Relaying information from various MISSNO subscribers is carried out according to the algorithms of this system [2].

The use of a helicopter equipped with such a relay complex will significantly increase the communication range of not only subscribers of the MV-DMV radio networks, but also of various MISSNO subscribers in the air-to-air, ground-to-air communication directions, especially ground-to-ground communication ".

The most effective application of CWRM in areas of local conflict, in the aftermath of emergency situations, the relay of radio signals from low-flying helicopters and aircraft or ground moving objects

in the conditions of mountainous, rugged or inaccessible terrain without a developed communication infrastructure.
