  skos:definition """SSTL developed the NigeriaSat-1 enhanced microsatellite during a know-how and technology transfer program for the Federal Ministry of Science and Technology (FMST) of Nigeria. NigeriaSat-1 is the first step in FMSTs plan to develop Nigerias national space infrastructure. The NigeriaSat-1 programme included the satellite, a mission control station in Abuja, Nigeria and hands-on training at Surrey for a team of Nigerian engineers. During the project, Nigeria formed a National Space Research and Development Agency (NASRDA), which now manages the NigeriaSat-1 program.
                
NigeriaSat-1 is a satellite of the standard Disaster Monitoring Constellation (DMC) design. It carries an optical imaging payload developed by SSTL to provide 32-m ground resolution with an exceptionally wide swath width of over 640 km. The payload uses green, red and near infrared bands equivalent to Landsat TM+ bands 2, 3 and 4. Images are stored in a 1-gigabyte solid-state data recorder and returned via an 8-Mbps S-band downlink.

NigeriaSat-1 can image scenes as large as 640 x 560 km, providing unparalleled wide-area, medium-resolution data. The data will be used within Nigeria to monitor pollution, land use and other medium-scale phenomena. .
                
In addition, NASRDA have joined the Disaster Monitoring Constellation (DMC) Consortium, and images from NigeriaSat-1 will be available to disaster relief agencies world-wide through the DMC data sharing system.

NigeriaSat-1 was launched in September 2003 from Pletsesk on a Kosmos launch vehicle, one of three satellites simultaneously launched to complete the first phase of the Disaster Monitoring Constellation, to provide medium-resolution imagery with daily worldwide revisit.

The objective is to provide a daily global imaging capability at medium resolution (30-40 m), in 3-4 spectral bands, for rapid-response disaster monitoring and mitigation.
