Zoom in on the map above and click on each partner organisation to see what part or parts of the SKA jigsaw they will be working on, and find out more about each partner and their own background.

The SKA design is a global effort by 12 international engineering consortia representing 500 engineers and scientists in 20 countries all feeding in to making the SKA a truly exceptional instrument. The list of partners is vast and can be seen all over the map above.

The consortia are responsible for working out the look and functionality of the different elements of the SKA, and ensuring that they will all work together. With a telescope of this nature, located on two different continents and generating unprecedented amounts of data, this is a formidable challenge.

The 12 consortia are made up of research institutions and industry partners which are spread across the globe, with each one having a designated lead institution that coordinates the work. They operate in conjunction with a specialist project manager based at SKA Headquarters in the UK.

Each consortium has been tasked with designing a particular element of the SKA – from the very visible parts like the dishes or the infrastructure at each site, to the essential software and networking that will allow the SKA’s arrays to act as one enormous telescope. In the final design, the different elements will come together like the pieces of a jigsaw puzzle.

Nine of the consortia focus on a component of the telescope, each critical to the overall success of the project, while three others focus on developing advanced instrumentation for the telescope. Click on the links below to find out more about each one and the institutions behind the design:

• Assembly, Integration and Verification (AIV)
• Central Signal Processor (CSP)
• Dish (DSH)
• Infrastructure Africa (INFRA SA)
• Infrastructure Australia (INFRA AU)
• Low-Frequency Aperture Array (LFAA)
• Signal and Data Transport (SaDT)
• Science Data Processor (SDP)
• Telescope Manager (TM)

Advanced Instrumentation Programme (AIP)

• Wideband Single Pixel Feeds (WBSPF)
• Mid-Frequency Aperture Array (MFAA)
• Phased Array Feed (PAF)

An essential part of each consortium’s role is to ensure that their design ultimately enables the SKA to achieve its science goals. This means scientists and engineers have worked closely together to ensure that the final design meets the science community’s requirements. To that end, the SKA formed the Science Working Groups (SWGs) to feed in to the process. You can find more details on the SWGs on the SKA Science site [external link].

Since the consortia were first formed in 2013, the design of the SKA has evolved in response to available funding and to take account of scientific advances. In December 2014, the process reached its first milestone, with the start of the Preliminary Design Reviews (PDRs). Each consortium presented its detailed proposals for assessment by an expert panel from the SKA and external organisations, and the results were fed back in to the ongoing design work.

There followed three years of effort by the international consortia to arrive at the Critical Design Reviews (CDR), which began in 2018. This is one of the last and most pivotal stages before construction can begin, where the design documentation for each part of the SKA is analysed in the finest detail, and determinations are made about the readiness of the consortia. Any actions recommended by the review panel must then be completed before the designs can be formally adopted. Once all the consortia have successfully reached this stage, the SKA’s design will be complete.

To learn more about the design elements and the consortia, check out our interactive CDR platform.

The CDR platform is designed to be a central hub for updates, chronicling each major step on the road towards SKA construction and showcasing the technological innovations that are making it possible.

As well as capturing international teams’ progress towards and beyond their CDRs, the platform features a wide range of news stories, profiles, case studies, photos and videos, providing context on the work that has been done so far.
