The ground station is part of the ground segment and allow the physical connection between the control center and the satellite. There are several types of ground station. For professional and commercial missions ground stations can be rent. It exists also service companies and support operations activities from satellite missions. Stations with parabolic antennas from 7m diameter can be used for the mentioned satellite missions. The antenna has a receiver for specific frequencies and similar for the transmitter. The tracking system of the antenna should comply also with minimal requirements like the tracking velocity.
The antenna of a ground station can be used for several purposes. The main function is the tracking of satellites, reception of telemetry and transmission of commands to the spacecraft. During the tracking the ground station measures the exact position of the satellite following the signal strength. This coordinates will be used later for orbit prediction. These coordinates help also to calculate the angle of elevation of the satellite. The distance from the satellite to the ground can be measured through the time delay of the transmitted signal and the received signal, like a radar. The distortion of the radio signal from the satellite due to the Doppler Effect is possible to measure the orbit velocity of the spacecraft.

Radio-Amateur License Course and Training
The preparation course for acquiring an international amateur radio license:
- Electronics for radio amateurs
- Radio transmitter and receiver technology
- Radio communication techniques
- Amateur radio regulations
- Training for the exam
- Satellite missions of amateur radio clubs
The course has a theoretical and a practical part, where the participants can immediately apply the knowledge acquired.
The course takes 5 days and teaching materials will be handed out. The number of participants is limited to 50 people.
SPECTRUM is not in charge of issuing licenses. The offered course is only an optimal preparation for the radio amateur license exam. Please contact the competent authority in your country to apply for a radio amateur licence.
