NigeriaSat-2 is a 300kg class earth observation satellite manufactured by Surrey Satellite Technology Ltd (SSTL) for the Nigerian space agency (NASRDA). Benefiting from a high performance camera with optical components manufactured by Optical Surfaces Ltd., the satellite has been able to capture stunning 2.5m resolution images enabling detailed analysis of ground structures, aircraft and vehicles.
NigeriaSat-2 carries two imagers: A 2.5m resolution panchromatic and a 5m resolution multispectral with a swath width of 20 kilometres. Using proprietary production techniques, Optical Surfaces’ skilled craftsmen produced the 385mm light-weighted primary mirror, and other optics in the Cassegrain camera, with a surface accuracy of lambda/20 p-v that has enabled the high resolution images taken by the satellite.
Optical Surfaces Ltd has produced optical components and systems for more than 45 years and is now accepted as one of Europe’s leading manufacturers of high-precision optics for satellite deployment and astronomical research. The company’s ISO 9001-2008 approved manufacturing workshops and test facilities are deep underground in a series of tunnels excavated in solid chalk where temperature remains constant and vibration is practically non-existent. With such stable conditions testing, particularly with long path lengths, becomes quantifiable and reliable. Working with these natural advantages is a highly skilled team of craftsmen with a commitment to excellence in both product quality and customer service.
