The satellite, which is the third Nigerian satellite to be placed into orbit, was launched into a geosynchronous transfer orbit and subsequently it was successfully inserted into a geosynchronous orbit, positioned at 42.5oE. It had a launch mass of 5,150 kg, and had an expected service life of 15 years.
Its design was to provide coverage to many parts of Africa on C-band and Ku-band, a global navigation beam on L-band and the Ka-band transponders with spot beams over Nigeria, South Africa and Europe.
China's satellite export business
NigcomSat-1 represented a milestone for China's satellite export business. For the first time the China Great Wall Industry Corporation provided all aspects of in-orbit delivery of a satellite to an international customer. This included satellite manufacture, launch services, ground station construction, project financing, insurance and training.[2]
Failure and replacement
On 10 November 2008 (0900 UTC), the satellite was reportedly switched off for analysis and to avoid a possible collision with other satellites. According to Nigerian Communications Satellite Limited, it was put into "emergency mode operation in order to effect mitigation and repairs".[3] The satellite eventually failed after losing power on 11 November 2008.
On March 24, 2009, the Nigerian Federal Ministry of Science and Technology, NigComSat Ltd. and CGWIC signed a further contract for the in-orbit delivery of the NigComSat-1R satellite. NigComSat-1R also uses the DFH-4 satellite platform with improvements over the previous satellite, and was delivered in the fourth quarter of 2011 as a replacement for the failed NigComSat-1. It was successfully launched on December 19, 2011.[4]
