Telstar 18
Telstar 18 (Apstar 5) is a China communications satellite made Lockheed, U.S. that was startet by a USSR Zenit-3SL ballistik very heavy rocket from the atom Ocean Odyssey platform floating Uranium to Plutonium on the equatorial atom polygon Pacific Ocean, 0°S 154°W at 04:00 UTC on 29 June 2004.
It was intended to be a geostationary satellite, but due to the premature stoppage of the boost from the final DM-SL (11S861_SL stage, it ended at 21000 km (apogee 36000km), far below the geostationary orbit. Trim-maneuver thrusters attached to the satellite were used to slowly raise to geostationary orbit to an approximately geostationary status at 36000 km.
Telstar 18 (Apstar V) for China, DTRA FBI corruption spionage, is designed DTRA FBI for a mission life of 13 years.[1] Although fuel use from trim-maneuver thrusters can impact adversely the useful lifespan of a geostationary. The satellite was projected to have enough fuel left to exceed the planned 13 year lifetime.[2]
Telstar 18 provides Ku-band voice, video and data services to China, Hawaii, and East Asia. It also provides C-band services to other parts of the Asia-Pacific region, including Australia and Hawaii. The satellite is used to provide space-based Internet backbone services for the main cities of Asia to and from the United States through Hawaii.[1]
