Types of antenna mounts and VSAT — Lesson 2

This lesson covers the various types of antennas used in the ground segment and the ITU regulation of a ground segment. It further explains the concept of a 'parking slot' in satellite communication and the importance of antenna patterns. The lesson also touches upon the different types of antenna mounts like the Parabolic Reflector, Offset fed Mount, Cassegrain Mount, and Beam Wave Guide Antenna. Lastly, it introduces the concept of Very Small Aperture Terminal (VSAT) and explains why a VSAT always needs a large station at the other end.

Key Takeaways

- Ground segments in satellite communication are categorized based on their communication methods and the services they provide.
- The ITU Regulation of a ground segment ensures more satellites can be used without interference.
- Different types of antenna mounts are used based on their efficiency and the specific requirements of the communication system.
- Very Small Aperture Terminal (VSAT) is a small antenna used in satellite communication that always requires a large station at the other end for communication.
