New South African nanosatellite to participate in international project

A South African nanosatellite will be launched into space from the International Space Station (ISS) during the first quarter of next year as part of an international research project under the European Commission’s Seventh (Research) Framework Programme (better known as FP7). The project is designated QB50.

The project will see 40 nanosatellites – often popularly called CubeSats – launched from the ISS to gather data on the lower thermosphere. The thermosphere is a 513 km thick region of extremely thin atmosphere above the earth, in which the ISS and low earth orbit satellites are to be found. The QB50 nanosatellites will operate for 6 to 18 months at altitudes between 200 km and 380 km above the earth.

The South African nanosatellite is named nSight1 and its development has been overseen by local private-sector company SCS Aerospace Group. This is the country’s biggest private-sector satellite business. “We are proud not only to be part of the QB50 project, but especially of the fact that it presents the opportunity to showcase South Africa’s ability in the space industry,” affirmed SCS Aerospace chairperson Dr Sias Mostert. “Almost all the systems and components on this satellite were manufactured and assembled within six months with South African partners.”

The prime contractor for nSight1 is SCS Aerospace subsidiary SCS Space. The other participating companies and institutions are, in the order listed by Mostert, the Space Advisory Company (SAC: another subsidiary of SCS Aerospace), Stellenbosch University, CubeSpace, Cape Peninsula University of Technology, Nelson Mandela Metropolitan University (NMMU), Pinkmatter Solutions, the Amateur Radio Society and NewSpace Systems (a further SCS Aerospace subsidiary – the group has a total of eight subsidiaries).

The nanosatellite was designed, integrated and tested by SAC engineers. This enterprise is focused on satellite systems engineering and has extensive experience, amounting to thousands of man-hours, in practical satellite engineering in the international satellite market. The design and engineering aspects of nSight1 covered by SAC were altitude control systems; communication systems; power systems; software; structural, thermal, optical and digital engineering; and system engineering.

nSight1 has a mass of about 2.5 kg and will also serve as a flight test platform. It will test fly SCS’ newly-developed Gecko imager and NMMU’s Radiation Mitigation VHDL Coding Technique, which has been patented. (VHDL stands for VHSIC Hardware Description Language; VHSIC, in turn, is the abbreviation for Very High Speed Integrated Circuit.)

The nanosatellite was assembled in the clean room of NewSpace Systems. This is an ISO 7 class facility, and the company uses only European Space Agency-certified technicians in it. It is unique in Africa. “The mission is a joint investment by SCS Aerospace group and Pinkmatter Solutions and forms part of a line of satellites to establish space heritage for a new generation of high- performance remote sensing cameras,” he highlights. “The camera technology being tested on the nSight1 nanosatellite was developed with initial support from the South African Department of Trade and Industry’s AISI (Aerospace Industry Support Initiative) programme.”

“As a producer of new-generation satellite ground segment software, Pinkmatter primarily serves the international satellite market,” explained Pinkmatter CEO Chris Böhme. “As a South African company, we are stronger by working together to provide more value to continue our success story in the international market. “We are proud to have cofunded the nSight1 mission, the first private South African satellite and thank all the engineers for the many days and nights of excellent work.” The company also provides data visualisation and modelling, statistical simulations, intelligence and law-enforcement applications, natural language processing and low level hardware/software integration.
