List of geostationary satellites

ICO-G1 was launched as a communications satellite by the American company ICO Global Communications (Holdings) Limited . The company later called itself DBSD, which changed the name of the satellite to DBSD-G1. In March 2012 the company was bought by Echostar.

Previous system not implemented

ICO-G1 is a successor to the ICO-F satellites with which the predecessor company ICO Global Communications later wanted to build a global satellite communications network, New ICO . The abbr. ICO stood for " I ntermediate C ircular O rbit".

The ICO-F satellites were developed by Boeing on the basis of the BSS-601 satellite bus. However, only two were completed and delivered, the first had a false start with a Zenit 3SL , while the second was successfully launched on June 19, 2001 with an Atlas 2AS in a circular orbit at an altitude of 13,390 km with a 45 ° orbit inclination. According to ICO, the satellite (ICO F2) was in operation and secured the frequency assignment for the global system that ICO had received from the ITU via the United Kingdom . The original plan was to build 15 satellites of this type, but the last three were canceled and Boeing's entire contract was terminated some time later.

In March 2012, ICO F2 was switched off. This is likely to be related to the takeover of the company by Echostar.

New system with geostationary satellites to supply the USA

ICO-G1 is the first satellite of a new concept based on geostationary satellites to cover the United States and not providing global coverage. The satellites are no longer being built by Boeing, but by Loral . ICO-G1 is equipped with a 12 m antenna for signals in the 2 GHz frequency range (S band) and is intended to enable mobile voice and data communication in North America (USA, Puerto Rico and the American Virgin Islands ). It was launched on April 14, 2008 with an Atlas V rocket. It is the heaviest satellite that has ever been brought into orbit with such a rocket. 30 minutes after take-off, the satellite separated from the last rocket stage and 15 minutes later the first signals were received. He has now taken up his normal duty.

The network identifier assigned by the ITU for the ICO network is 901-01.
