h1. Satellite Link Budget

In this section we are going to explain what is a satellite link budget and what are the main parameters it involves.

h2. Satellite Communication System

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_.
* The _space segment_ contains the satellite itself (or satellite constellation) and the uplink and downlink satellite links.
* The _ground segment_ consists of all the traffic earth stations.
* The _control segment_ consists of the ground facilities and systems for control and monitoring the satellite.
