Sinosat 1

 1998-044A


After the mixed results of the EurasSpace (DASA/CASC) DFH-3 project, EurasSpace turned to Aerospatiale/Cannes for the Sinosat 1 satellite. Dornier Satellitensysteme GmbH was the official prime for the satellite, but Aerospatiale/Cannes built the spacecraft in collaboration with Chinese engineers. Shortly before launch, the Cannes facility became part of Alcatel Space Industries. Launch was by CZ-3B in July 1998. The Spacebus 3000A satellite's launch mass is 2820 kg, 1600 kg BOL. 26m span. After launch and early orbit checkout, EurasSpace delivered Sinosat to Sino Satellite Communications Co. (Sinosatcom) of Beijing. Sinosat was also called Xinnuo 1.

The CZ-3B stage second burn was about 2.84km/s, requiring a mass ratio of 1.93 and the post-burn mass was around 5820 kg including payload assuming 200 kg residual fuel. This implies a propellant usage of 5400 kg.

Capacity on Sinosat was leased by Intelsat as Intelsat APR-1.
