“Viewnok” - a training complex that allows you to receive radio signals from spacecraft.

The complex includes two stationary antennas in the ranges 136..146 and 435 … 438 MHz.

It is based on the so-called software-defined radio. This means that operations such as filtering and demodulating the radio signal are carried out mainly by software, and not by electronic filters and devices, as in “ordinary” receivers. This allows you to receive completely different signals with the same receiver using suitable programs.

The following types of radio signals are available:

telegraph radio signals that allow:

• receive Morse code signals “by ear”,
• demonstrate the effect of Doppler;

- images from weather satellites NOAA, Meteor-M, with which you can:

• see the development of weather phenomena,
• study the temperature distribution;

- telemetry of approximately 50 satellites to evaluate:

• heating the apparatus on the sunny side of the coil and cooling in the shadow zone,
• satellite rotation speed.
