“Ak Kayyn” station is a mobile complex, which integrates different radio devices, providing a multi-channel radio link in 2 directions due to tropospheric propagation. station equipment intended for the deployment of a single multi-interval interval and tropospheric communication lines. Communication range from 80 to 210 km, the number of intervals - 5.

Main technical characteristics:

HF and VHF communications

• VHF - ensures operation in the range of 30 to 87.975 MHz and is designed to negotiate the vehicle cab when moving stations in the column.
• HF radio - ensures operation in the frequency range from 1.6 MHz to 30 MHz and is designed to negotiate with presetting tropospheric line.

The frequency range of equipment provides for simultaneous operation of reception and transmission without manual search and tuning frequency in the frequency range from 4400 MHz to 5000 MHz is broken down into two sub-bands:

a) the lower "H" - from 4400 MHz to 4630 MHz;

b) the upper "V" - from 4770 MHz to 5000 MHz.

Data rate

Speed transmission / reception of information flows group tropospheric link: 64.256, 512, 2048 kbit / s.

Interfaces closure

Station equipment provides the following interfaces interfacing with the terminal equipment 2-wire telephone channel; 4-wire telephone channel; C1-PL-BI; E1; HDB3; Ethernet.

Transmitting and receiving antenna

Antenna Type - cutting the paraboloid of revolution with aperture 1400 × 1600 mm and a focal distance of 700 mm.

Work rotation sector antenna station, at least:

• on the horizontal axis pointing - 358 ° (from minus 179 ° to 179 °);
• for vertical guidance axis - 63 ° (minus Z ° to 60 °).

• on the horizontal axis pointing - 6 ° / s;
• for vertical guidance axis - 2 ° / s.

Navigation equipment

The station is equipped with navigation equipment operating by signals of satellite navigation systems GLONASS and GPS, for correcting the frequency of the reference oscillator, the correction of the clock control system, determining the coordinates for the deployment of tropospheric tropospheric stations and lines.

Initial guidance modes

Station equipment provides the following guidance modes correspondent:

• automatic guidance in accordance with the calculated target designation on the basis of input longitude and latitude correspondent;
• guidance based on manually entered target designation (azimuth and elevation).

Output power

Output level of each transmitter of at least 100 watts.

Autonomous power

Power station provided from an external single-phase AC voltage of 220 V, a frequency of (50 ± 2) Hz, as well as from its own diesel units.

Additional equipment

• Field telephone.
• Remote dispatch communication for the organization line intercom.
• xDSL modem for transmitting a digital stream.

The life support system

Tropospheric relay station is equipped with a fan heater capacity of at least 2 kW, the heating system (heating) OM-65, FVUA filtering unit, an air conditioning system with a cooling capacity of 2,000 watts.

Habitability crew

For the convenience of the crew in the back are located wardrobes, beds for rest 3 people. Sun beds can be transformed into new jobs. The lighting system provides unobtrusive and blackout emergency lighting at night.

Service and warranty service

Plant provides warranty service during the years of operation, after the acceptance of the product. Possibility of training of customer's specialists to the rules and methods of operation of the equipment. If necessary, there is a possibility of organizing a service center on-site maintenance of Customer Equipment.

On request to change the composition of the equipment, do not affect the basic performance characteristics of the product.
