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]
