The on behalf of TerreStar Networks Inc., developed by Space Systems / Loral satellite was on 1 July 2009 at 17:52 UTC by an Ariane 5 ECA launch site in Kourou ELA -3 into a geostationary transfer orbit, from 249.9 to 35,941 km height of 6.01 ° inclination, brought. In use, the satellite should be positioned in geostationary orbit at 111 degrees West. The satellite is equipped with a launch mass of 6902 kg the heaviest destined for geostationary orbit commercial satellite. He left 26 minutes after the launch of the rocket.

TerreStar -1 uses the S-band from 2.0 to 2.2 GHz, using a 18 meter antenna that can produce up to 500 illuminate areas on a phased array. It offers mobile voice, data, surveillance and intelligence services in the U.S. and in large areas from Alaska to Hawaii and Puerto Rico are available. The mobile terminals required for this are not larger than normal phones that do without larger antenna thanks to its high power of the satellite. The connection to the ground station via a standard Ku-band antenna.
