  1. You can see on the map the current location of satellite on the orbit, projection of orbits on the Earth’s surface, satellite’s field of visibility above the horizon and location of the receiving station.
  2. You can see on the radar a current location of the satellite in the sky. Zenith is in the center. Cardinal pIn the window Parameters of orbit are basic parameters of orbit, time of the closest уvent and doppler’s shift.oints are marked with letters: N - north, S – south, W – west, E – east.
  3. In the window Parameters of orbit are basic parameters of orbit, time of the closest уvent and doppler’s shift.
  4. You can add satellites and change appearance of the interface n the settings of the program.
  5. You can update satellite’s orbital parameters in menu and change settings of radio transmitter and rotating system.
