About SKA

About the Square Kilometre Array, the upcoming world project in radio astronomy

The Square Kilometre Array (SKA) is a technology project of superlatives and will be the biggest and most sensitive radio telescope in the next 50 years. The scientific capabilities promised by the SKA and its technological challenges provide an ideal base for interdisciplinary research, technology transfer, and collaboration between universities, research centres and industry. The SKA is on the roadmap of the European Strategy Forum for Research Infrastructures since 2006 and has been recognised, with the E-ELT, as the essential facilities for European research in astronomy.

The SKA will be the world's premier imaging and surveying telescope that, with a combination of unprecedented versatility and sensitivity, will open up new windows of discovery space. The expected science return of an observatory like the SKA will be overwhelming, making not only fascinating discoveries on its own but also providing exceptional complementarity in the exploration of the Universe's most fundamental open questions. With the capabilities the SKA offers it will provide insight into the key science questions such as, the formation and evolution of the first stars and galaxies after the ``big bang'', the nature of gravity, the history of neutral hydrogen, the role of cosmic magnetism, and possibly life beyond Earth.

The SKA will be made out of two different types of antenna arrays and is the next generation radio-interferometer with superior surveying capabilities allowing to scan the Universe from 50 MHz up to tens of Giga Hertz. The data rates produced by the SKA (thousand times higher than the current world wide web) will trigger innovations and developments in information technology and novel techniques in data analysis and HPC computing. In the upcoming decade the SKA will be built in two phases in South Africa and Australia, whereas the headquarter remains in the United Kingdom. Between 2018 to 2023 a subsets of the SKA-MID- and SKA-LOW components will be constructed as Phase 1, before scaling up to the full SKA by the late 2020s. Early science can be expected as early as 2020.

The tendering and procurement of Phase 1 will take place in 2018. The call for tendering is in general open, but a just retour mechanism has been installed only considering industrial applications of SKA member countries.


Precursor Facilities of SKA

The SKA will benefit from a number of ongoing precursor facilities. These are the Murchison Widefield Array (MWA) and the Australian SKA Pathfinder (ASKAP) in Australia and MeerKAT in South Africa. German scientists are collaborating with all three SKA precursors, German companies play a major role in the construction of MeerKAT.

The SKA-MPG telescope is a 15-m aperture offset-Gregorian dish constructed by the MT Mechatronics GmbH in collaboration with the Max-Planck-Institut für Radioastronomie (MPIfR). This telescope is the first prototype dish of the South African Square Kilometre Array (SKA)-MID component built in the Karoo desert, South Africa with help from the SARAO. The telescope is located near the MeerKAT- and SKA-MID-configuration (SKA-TEL-INSA-0000537) and is specially suited for an independent scientific programme. This telescope will be equipped with S- and Ku-Band receiver systems, both developed by the MPIfR, and depending on the scientific merit additional frontends could be installed in the future. The S-Band receiver has a bandwidth of 1.75 GHz covering the frequency range 1.7 to 3.5 GHz, and the Ku-Band receiver covers the 12 to 18 GHz frequency range with 2×3-GHz bandwidth, 12-bit digitizer.
