Pioneers of Radio Astronomy

The Square Kilometre Array will be the largest radio telescope ever built and will produce science that changes our understanding of the universe. In Africa the SKA will be built in South Africa and eight other African Countries. The South African Radio Astronomy Observatory (SARAO), a facility of the National Research Foundation, is responsible for managing all radio astronomy initiatives and facilities in South Africa, including the MeerKAT Radio Telescope, Geodesy and VLBI activities.

MeerKAT in Northern Cape, South Africa

The South African MeerKAT radio telescope, situated 90 km outside the small Northern Cape town of Carnarvon, is a precursor to the Square Kilometre Array (SKA) telescope and will be integrated into the mid-frequency component of SKA Phase 1. The MeerKAT telescope is an array of 64 interlinked receptors (a receptor is the complete antenna structure, with the main reflector, sub-reflector and all receivers, digitisers and other electronics installed). Discover how the MeerKAT telescope is built.

26m and 15m radio telescope for radio astronomy and geodesy in Hartebeesthoek Site, Johannesburg, South Africa

SARAO Hartebeesthoek Site is located west of Johannesburg, South Africa. built in 1961 by the National Aeronautics and Space Administration (NASA) of the United States of America. An 85 foot = 26 metre diameter antenna was used to get data from, and send commands to, many unmanned US space probes going beyond Earth orbit. Discover Astronomy Instruments in Hartebeesthoek Site
