NigeriaSat-2, Nigeria's second satellite, was built as a high-resolution earth satellite by Surrey Space Technology Limited, a United Kingdom-based satellite technology company. It has 2.5-metre resolution panchromatic (very high resolution), 5-metre multispectral (high resolution, NIR red, green and red bands), and 32-metre multispectral (medium resolution, NIR red, green and red bands) antennas, with a ground receiving station in Abuja. The NigeriaSat-2 spacecraft alone was built at a cost of over £35 million. This satellite was launched into orbit by a military base in China. On 10 November 2008 (0900 GMT), 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 to effect mitigation and repairs". The satellite eventually failed after losing power on 11 November 2008. On 24 March 2009, the Nigerian Federal Ministry of Science and Technology, NigComSat Ltd. and CGWIC signed another contract for the in-orbit delivery of the NigComSat-1R satellite. NigComSat-1R was also a DFH-4 satellite, and the replacement for the failed NigComSat-1 was successfully launched into orbit by China in Xichang on 19 December 2011. The satellite was stated to have a positive impact on national development in various sectors such as communications, internet services, health, agriculture, environmental protection and national security.
