The satellite called nSight-1 is a product of the Somerset West-based SCS Aerospace Group (SCSAG), Africa’s largest privately-owned group of satellite design and manufacturing companies with more than 25 years of experience in this domain. It was launched from the International Space Station during May last year with 28 other satellites as part of the European Space Agency’s QB50 project which collects research data from the earth’s lower thermosphere.
“We are delighted and extremely proud of the performance of our satellite nSight-1. It is in a stable and healthy state and the various on-board payloads are working well and have resulted in a number of major sub-systems sales to international clients,” says Francois Denner, Managing Director of the SCS Aerospace Group.
“The success of nSight-1 certainly strengthens our position to play a leading role in forging a new satellite business cluster in the South African economic sector. Our group now has the ability to manufacture up to 80% of small satellite components locally. We are proudly South African,” says Denner.
The three companies in the SCS Aerospace Group which are directly involved in providing commercial satellite solutions are Space Advisory Company SAC their satellite programme and systems consulting and engineering house; SCS Space which provides satellite mission solutions as well as satellite systems; and NewSpace Systems which develops and manufactures high-quality space components and sub-systems. The group employs some 90 highly trained satellite specialists such as electronic, systems, software and mechanical engineers.
According to Hendrik Burger, CEO for SCS Space, the primary contractor for the nSight-1 nanosatellite, the Attitude Determination and Control System (ADCS) used on board is one of the most advanced used in a satellite this size. This is another South African product designed and manufactured by CubeSpace (www.cubespace.co.za). It has given the satellite a high degree of pointing accuracy to orientate in its orbit some 400km above Earth. They are now looking at extending the expected orbit lifetime of the satellite from 18 to 24 months due to its low drag, specific mass and orientation control.
The milestone achievements for their satellite so far are the following:
· Their primary science payload (FIPEX) to feed regular data for thermosphere analysis to the Von Karman Institute for Fluid Dynamics is working well by providing double the contracted data volume;
· The Gravity Wave Experiment is producing measurement data that is being processed by Mr. Philip Wagner (the South African creator of the experiment);
· Ongoing radiation impact detection results are being monitored by the Radiation Experiment and delivered to the Nelson Mandela Metropolitan University (NMMU) for interpretation;
· Their SCS Gecko Multispectral Imager has been seamlessly producing high-quality pictures that are made freely available. The Space Advisory Company was awarded with the “Best Innovation Concept for a medium enterprise” award for the Gecko imager development during the 2017 Da Vinci Top Technology (TT100) Awards, South Africa’s foremost technology innovation awards;
· The Grabouw-based ground station that controls the satellite is autonomously operating and will in the future form part of an international network of satellite ground stations servicing the ever-growing need by Lower Earth Orbit satellites.
“The nSight-1 mission demonstrates the ability of the SCSAG to leverage the capabilities in the South African space industry cluster. Thank you to all the South African project partners including SCS Space, Space Advisory Company, NewSpace Systems, Pinkmatter Solutions, the Department of Trade and Industry, Stellenbosch University, CubeSpace, Denel Spaceteq, DeltaV Aerospace, Simera Technology Group, Cape Peninsula University of Technology, Nelson Mandela Metropolitan University and the Amateur Radio Society, who made this possible,” Denner concluded.
