2.1 Understand satellite
system elements
In satellite communication system, various operations take place.
Among which, the main operations are orbit controlling, altitude of
satellite, monitoring and controlling of other subsystems.
A satellite communication consists of mainly two segments as
shown in Figure 2.1. Those are space segment and earth segment. So,
accordingly there will be two types of subsystems namely, space
segment subsystems and earth segment subsystems. As shown in
the Figure 2.1, the communication takes place between space seg-
ment subsystems and earth segment subsystems through
communication links. The visualization of two segments between
space and earth in the satellite system is shown in Figure 2.2.
