A US private space-company usually servicing US military satellittes has proposed a way to re-use decommisioned geostationary satelittes for communication puposes.

DARPA's Phoenix program, which seeks to develop technologies to cooperatively harvest and re-use valuable components from retired, nonworking satellites in geostationary orbit 37000km above Earth.

The goal is to demonstrate the ability to create new space systems at greatly reduced cost compared to developing, building and launching brand new replacement satellites.
