Nigeriasat-X EMS100 (Enhanced Micro Satellite 100)
Capacity building is central to the implementation of the Nigeria Space Programme. As part of the Know-How Technology Traning (KHTT) on the NigeriaSat-2 satellite project is the development of a training model (TM) named - NigeriaSat-X. The TM will be used to give the KHTT's hands on experience in the requirements specification, project management, system engineering, manufacture, test, assembly / integration and final system testing of a spacecraft. Unlike the NigeriaSat-1 TM, NigeriaSat-X will be built to flight specification and will be launched along with NigeriaSat-2. Twelve (12) Nigerian Engineers and Scientists are involved in the building of the satellite using SSTL facilities since September 2006.
NigeriaSat-X EMS100 key features include:
- 22m next generation imager with improved resolutions and optics over the same swath areas as DMC+;
- Max swath 600km @ 8bits
- High rate X-band downlink set to 20MBps
- Low rate S-Band 8MBps
- 2 x 2Gbyte data recorders
The Nigeriasat-2 sensor will provide imagery at 3 resolutions - 2.5m panchromatic, 5m multi-spectral (RGB, NIR) and 32m multi-spectral. The Nigeriasat-X sensor will provide 22m multi-spectral (RGB, NIR) imagery. The volume of imagery expected from Nigeriasat-2 is about 250 images per day. A long-term storage for approximately 7.2 years of steady collection and processing capacity for 100 images per day is being planned. The imagery volume from Nigeriasat-X has been estimated to be a handful of images per day, sharing many of the same storage and processing capabilities from the Nigeriasat-2 system.
