| 7 | 3 | RIBAS MACHADO, Ederson | Assuming that a telecommunication system is composed by a transmitter a medium and a receiver, the link budget is the accounting of all gains and losses in the power signal from the transmitter, passing through the medium, to the receiver. To easily understand, we can analyse the satellite system showed in figure 1. |

| 10 | 1 | SERRA FONT, Anna | To fully understand what is the link budget first we must understand how it is formed a satellite communication system. A satellite system is composed of three operational components: the _ground segment_, the _space segment_ and the _control segment_. |
| 11 | 1 | SERRA FONT, Anna | * The _space segment_ contains the satellite itself (or satellite constellation) and the uplink and downlink satellite links. |
| 12 | 1 | SERRA FONT, Anna | * The _ground segment_ consists of all the traffic earth stations. |
| 13 | 1 | SERRA FONT, Anna | * The _control segment_ consists of the ground facilities and systems for control and monitoring the satellite. |
