Synergy of systems: the GMRT and SKAO

Impact

The Giant Metrewave Radio Telescope (GMRT), a world-class facility located in India and operated by NCRA, has served as a crucial "pathfinder" for the SKAO. This collaboration exemplifies a powerful synergy, where GMRT provided a real-world testbed for SKAO's cutting-edge technologies, while simultaneously receiving a significant technological upgrade.

During the conceptual and design phases of the SKAO's Telescope Manager, there was a need for a practical platform to test the novel software ideas and architectural designs. At the same time, the GMRT required a modern Monitor and Control (M&C) system to replace its aging, legacy infrastructure.

Recognising this opportunity for mutual benefit, NCRA decided to develop the new M&C system using the same design principles and TANGO Controls software framework selected for the SKAO's Telescope Manager. This decision allowed the SKAO design ideas to be tested and refined in a live, operational environment, much like an advanced prototype development. NCRA also engaged its industry partners, including one of the key companies involved in the SKAO's design, ensuring a seamless and collaborative development process.

The result was a resounding success. The GMRT was equipped with a fully functional, state-of-the-art M&C system, significantly enhancing its operational efficiency and capabilities. This new system also served its secondary, but equally important, purpose: it helped to "shake down" and validate the design ideas for the SKAO's Telescope Manager, proving their viability and paving the way for their implementation in the final observatory.

This case study perfectly illustrates the collaborative model between the SKAO and its pathfinder facilities, where each provides invaluable support to the other, leading to shared success and innovation.
