South Africa's most advanced satellite to support Operation Phakisa 

The Minister of Science and Technology, Mmamoloko Kubayi-Ngubane, in a ceremony to send off South Africa's second nanosatellite to India, where it will be launched on 18 July. 

ZACUBE-2, described as the most advanced on the continent, will provide cutting-edge remote sensing and communication services to South Africa and the region. The 4 kg ZACUBE-2 was developed by the French South African Institute of Technology (F'SATI) at the Cape Peninsula University of Technology (CPUT). 

F'SATI is a French South African postgraduate institute for teaching, research and development with two nodes – one at Tshwane University of Technology and one at CPUT. 

The project was funded by the Department of Science and Technology (DST), and managed by the South African National Space Agency (SANSA), in close cooperation with the University of Montpellier, the French Embassy and the Paris Chamber of Commerce. 

The primary mission objective of ZACUBE-2 is to demonstrate vessel-tracking services in the South African Exclusive Economic Zone in support of the Oceans Economy component of Operation Phakisa. Operation Phakisa is intended to fast-track the implementation of the National Development Plan. 

The 10 x 10 x 10 x 30 cm satellite will track vessels along South Africa's coasts, with its automatic identification system (AIS) payload providing information on their position, speed and registration.  The AIS will also proactively detect forest fires through an imager payload developed by the Council for Scientific and Industrial Research (CSIR). 

CPUT adopted Operation Phakisa as a key focus area, specifically using research and technology to innovate for marine protection and governance. The university has agreements with both the Department of Science and Technology and the Department of Environmental Affairs for the development of nanosatellite-based solutions for Operation Phakisa.

In June 2016, the university launched its Research Chair in Oceans Economy, cementing its overall contribution to Operation Phakisa. ZACUBE-2 is a precursor to a constellation of nanosatellites that will be developed to facilitate South African marine domain awareness.  This will support international maritime communications, from the current AIS to the evolving VHF Data Exchange Service. 

Speaking at the send-off, Minister Kubayi-Ngubane welcomed the successful development of the nanosatellite, as monitoring the continental shelf was a critical part of Operation Phakisa and required a dedicated low-cost solution.

"The Department of Science and Technology saw an opportunity to contribute to Operation Phakisa by ensuring that the country can monitor its 3 000 km coastline effectively," said the Minister. 

The Minister said space science and technology were capital-intensive, and the government had a role to play in creating an environment in which the local space industry could thrive.  She said that projects like the development of ZACUBE-2 benefited not only the space industry, but also the manufacturing and downstream application development industries. 

Ambassador of France to South Africa, Christophe Farnaud said his country was very proud to be part of this adventure. “Space is about science, economy, innovation and more than that. Space is also a dream – we dream together, we build together.” 

SANSA CEO, Dr Val Munsami said the agency strove to grow the local space industry through products, services and skills development. “Supporting such programmes as ZACUBE-2 enables the country to benefit from trained and experienced young space engineering experts.”


New book available from Amazon - kindle or soft cover

This book provides a comprehensive guide to how you communicate through amateur radio satellites and how to receive signals from other small satellites and 'weather' satellites.
Amsats and Hamsats gets right into the techniques you will need for working amateur radio stations through amateur radio satellites, then it moves on to listening, or watching, signals from satellites.

There are chapters answering questions like, "how do satellites stay in orbit" and "why are they so expensive to launch?" Followed by sections about the history of amateur radio satellites, the mathematics governing orbits, different types of satellite and their orbits. It covers the equipment you need, to track and use the amateur satellites and some of the satellite tracking software that is available. There are detailed sections covering feeders, Masthead preamplifiers, antenna systems and automated rotator control. There are the details of FUN cube Satellites, Weather Satellites and even the International Space Station. If you want to know the art of the possible and what satellites ae available, where they are, new ones that are planned and even the bands you can operate. There is much more besides, as Amsats and Hamsats provides the ultimate guide to operating satellites.

A flight-ready solar panel for Kletskous.

The solar cells are glued to the PC board using conductive silver epoxy. This is done under vacuum to prevent bubbles being formed in the epoxy. Bubbles may burst in the vacuum of space, fracturing the paper thin glass solar cell and destroying it in the process.

African Radio Amateurs will soon have access to a geostationary satellite

In the next few years radio amateurs will have access to two geostationary platforms, one that will service the Americas and another one, particular attractive to South Africans, that will be  positioned at 26° East giving 24 hour access to Africa, Europe and the Middle East. These two geostationary projects will be included in commercial platforms similar to Amateur Radio Satellite (AMSAT) South Africa seeking to have an amateur radio transponder included in South Africa’s next satellite currently designated as EOS-1 (Earth Observation Satellite).
