and OBS (On-Board-Switching)
technologies, ISL (Intersatellite Links)
- Multibeam systems. Access techniques: transponder hopping, SS-TDMA (Satellite
-Switched TDMA), beam scanning.
- VSAT (Very Small Aperture Terminals)
networks. Network configurations. Hub station and user equipment.

Projects
Selected aspects of satellite system
designing. Starting from
predefined link
quality requirements (BER, availability), and dimension of the
transmitting
ground station equipment calculate
link
resource usage. Example:
for specified
transmission and quality parameters choose
satellite (transponder) suitable for assumed connection
and define
ground station parameters (antenna gain, output power, modulation and
coding
schemes).
