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.
Satbeams was started from the idea to combine the satellite footprints with Google Maps and as a result www.satbeams.com web portal went life in April 2008.. In January 2010, veteran sat-frequency web site SatcoDX was shut down after more than 30 years of being online and in order to maintain the service for SatCom/TV community they redirected traffic to SatBeams.
In 2002, the satellite's main spacecraft control processor failed, prompting DirecTV to move the spacecraft into a storage orbit. [27] The satellite was recalled in October 2003 and leased to Telesat, relocating to 82° W in order to provide backup for Nimiq 2. [28] In 2004, the satellite was relocated to 91° W, backing up Nimiq 1.
Coverage maps are designed to indicate the service areas of radiocommunication transmitting stations. Typically these may be produced for radio or television stations, for mobile telephone networks and for satellite networks. For satellite networks, a coverage map is often known as a footprint.

Astra 2B is one of the Astra communications satellites owned and operated by SES.Launched in September 2000 to join Astra 2A at the Astra 28.2°E orbital position providing digital television and radio broadcast services to the United Kingdom and Ireland, the satellite has also served at the Astra 19.2°E and the Astra 31.5°E positions.
From materials to labor and other equipment, TV and film production can often have a huge carbon footprint. A recent report found that big-budget feature films had a carbon footprint of over 3,000 ...
Astra 1E (1995) was dedicated to digital satellite TV services for Europe and subsequent satellites launched to Astra 19.2°E were also all-digital in the traffic they carried. Hand-in-hand with the switchover to digital transmission of TV by satellite came a shift to encryption and the targeting of channels to individual countries or regions.
