SKA Africa

What SKA Africa does

SARAO (South African Radio Astronomy Observatory), operating as SKA Africa, is a national research facility under the National Research Foundation (NRF) of South Africa that manages all radio astronomy initiatives and facilities in the country on behalf of the Department of Science, Technology and Innovation (DSTI). The organisation's flagship asset is the MeerKAT radio telescope — a 64-dish array situated approximately 90 km outside Carnarvon in the Northern Cape — which serves as a precursor to the Square Kilometre Array (SKA) and is designated for integration into the mid-frequency component of SKA Phase 1. SARAO also operates the Hartebeesthoek Radio Telescope Site (a 26m and 15m antenna facility originally built by NASA in 1961 for deep-space probe tracking) and supports additional instruments including KAT-7, HERA (Hydrogen Epoch of Reionization Array), the African VLBI Network (AVN), and the C-Band All-Sky Survey (C-BASS). The organisation develops proprietary Digitiser/Sampler Module Technology for radio signal processing.

SARAO's revenue model is non-commercial: funding flows from the South African national budget via DSTI appropriations through the NRF, and telescope observing time and data are allocated to the global scientific community through competitive proposal processes rather than paid contracts. Customers fall into three primary segments — global professional astronomers and research institutions (the core scientific users of MeerKAT and other facilities), graduate and postgraduate students in astronomy, physics, engineering and data science (served through scholarships, postdoctoral fellowships, and a Radio Astronomy Skills Workshop programme), and the general public (engaged via public open days, the Mission MeerKAT cartoon series, the Shared Sky Exhibition, citizen science projects such as 'Bursts from Space', and a Carnarvon astro-tourism guide programme). The go-to-market is community-led, anchored on scientific discovery, human capital development, and international mega-science collaboration through the SKA Organisation and other partners.

Core offering

SKA Africa (operating as NRF/SARAO) manages South Africa's national portfolio of radio astronomy facilities, including the MeerKAT Radio Telescope and the Hartebeesthoek Site, and leads the country's participation in the Square Kilometre Array (SKA) project. The organization provides observing time, telescope data, and research funding to the global scientific community through competitive proposal processes, and supports education via scholarships, fellowships, an e-learning portal, and citizen science initiatives.

Product overview

NRF/SARAO operates a portfolio of radio telescopes and scientific instruments centered around the MeerKAT Radio Telescope as the primary facility and precursor to the Square Kilometre Array (SKA). The core products include the MeerKAT telescope (located in Northern Cape), the SKA telescope project, the Hartebeesthoek Site with 26m and 15m antennas for geodesy and VLBI, and supporting instruments KAT-7, HERA, AVN, and C-BASS. Supporting infrastructure includes the MeerKAT Astrophysics Data System Library for research publications, SARAO E-learning Portal for education, and a Citizen Science Project for public engagement. SARAO also develops proprietary Digitiser Technology (Sampler Module Technology) for telescope applications. These products form an integrated radio astronomy ecosystem spanning observation, data management, and education.
