Scientists to extend the lives of satellites Sep 11, 2007
Communications satellites occupy a narrow band of space called geosynchronous orbit that rings the equator about 22,500 miles aloft where they keep an exact pace with Earth's rotation so their antennae can remain pointed at the same place for communications purposes.

Engineers Rescue Aging Satellites, Saving Millions Sep 9, 2007
"Communications satellites cost about 100 million and sometimes as much money to launch them into a geosynchronous orbit. They generally have a 15-year lifetime, bringing in 5 million to 10 million a month in revenue.Understandably, broadcast companies are very concerned about when a satellite needs to be replaced," said Collicott, who has been developing the simulation since the early 1990s. "A lapse in service would have tremendous impact on their business.". (Science Daily)

One critical part of the equation likely will be new launch vehicles capable of carrying heavy payloads to geosynchronous orbit at a much lower cost than the vehicles of today, Smith said. Significantly reduced launch costs will be critical as limitations with solar array technology, another technology that will need to be advanced to enable space-based solar power, likely will require a large constellation of satellites to handle a small percentage of energy consumption, Smith said.
