CALL FOR PAPERS FOR THE ANNUAL AMSAT SPACE SYMPOSIUM 2014
The annual SA AMSAT Space Communication symposium will be held on Saturday 24 May 2014 at the Innovation Hub in Pretoria.
Proposal for papers are now called for. Submit a brief overview of the planned paper by 15 March 2014 to firstname.lastname@example.org. Authors will be advised of the acceptance of their paper by 31 March. The final written paper will be requited by 30 April and PowerPoint presentation by 15 May. Please also include a short CV and a photograph of yourself.
Registration for the symposium will open on 1 February. Details will be available soon
SIGNIFICANT MILESTONE FOR SKA
The first scientific paper based on observations performed with South Africa's new KAT-7 radio telescope, has been accepted for publication by the prestigious journal Monthly Notices of the Royal Astronomy Society. "This is a significant milestone for South Africa's SKA project, proving that our engineers are able to deliver a cutting-edge scientific instrument, and that our scientists are able to use it for frontier science," says Derek Hanekom, South Africa's Minister of Science and Technology.

DEON COETZEE ZR1DE RECEIVES THE MTN GARTH MILNE TECHNOLOGY AWARD
The MTN Garth Milne Technology Award was presented to Deon Coetzee ZR1DE for his support of the SA AMSAT KLETSkous cubesat project at the annual South African Amateur Radio Development Trust Award ceremony.
Deon has designed and developed a space frame that meets international standards and can be launched from the cubesat launch carrier. To date he has built two prototypes and is currently building a third prototype which could become the flight model. In addition he is also working on a mechanism that will allow solar panel to deployed which will provide a great deal more available power to operate the payload. Listen to Deon as he describes the project
SA AMSAT ACCELERATING THE KLETSkous CUBESAT PROJECT
SA AMSAT has decided to accelerate their CubeSat project, named KLETSkous and expect to have the first prototype version of the transponder and control system on the table for testing by end February."One of the reasons to speed up development is the quest to have the transponder included as an experimental payload on the ARMC project." Hannes Coetzee, ZS6BZP said. Jacques Roux, ZR1ADC is working on the transponder while Brian McKenzie, ZS1BMN is responsible for the control systems.

DYNACUBE TO EXPLORE THE SOUTH ATLANTIC ANOMALY
After launch DynaCube, a one-unit CubeSat being constructed by Interns at the Denel Dynamics Engineering Academy will be exploring the South Atlantic Anomaly during orbits over the area.
The South Atlantic Anomaly (SAA), off the coast of Brazil, is an area where the Earth's inner Van Allen radiation belt comes closest to the Earth's surface dipping down to an altitude of 200km This leads to an increased flux of energetic particles in this region and exposes orbiting satellites to higher than usual levels of radiation. The effect is caused by the non-concentricity of the Earth and its magnetic dipole. The South Atlantic Anomaly is of great significance to satellites and other spacecraft that orbit the Earth at several hundred kilometres altitude; these orbits take satellites through the anomaly periodically, exposing them to several minutes of strong radiation, caused by the trapped protons in the inner Van Allen belt.
The team, all engineers who graduated from various universities in South Africa, spent last year working on the project to gain practical experience before they are assigned to various departments in the company. The Interns were tasked with designing, manufacturing and commissioning a 1 U Cube Satellite and its associated ground support systems. Three teams were formed, with each team having specific objectives. Team Ground Zero was responsible for the Ground Control Station as well as communications equipment on-board the satellite. Team Virtuoso was responsible for the On-board Computer (OBC), the power system, the satellite structure and telemetry data. The main tasks of Team Frodo were to specify the satellite payload, the required sensors, the attitude control and the launch of the satellite.
