Footprint (satellite)

File:Satellite Footprint.png

An example of an elliptical footprint with a reception area of Germany, Austria and Switzerland. The ellipses indicate the necessary antenna diameter for receiving in cm.

The footprint of a communications satellite is the ground area that its transponders offer coverage, and determines the satellite dish diameter required to receive each transponder's signal. There is usually a different map for each transponder (or group of transponders), as each may be aimed to cover different areas.<ref name="satstar"/><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Footprint maps usually show either the estimated minimum satellite dish diameter required or the signal strength in each area measured in dBW.<ref name="satstar">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
