LJMU is conducting a pre-market engagement exercise to gauge the capabilities of the market for our requirement. This is not a call for competition/ ITT. This process enables LJMU to fully understand the market to assist us in drafting our tender documentation / determining next steps. Liverpool John Moores University (LJMU), through its Astrophysics Research Institute (ARI), is undertaking a pre-market engagement exercise relating to the planned upgrade of the Liverpool Telescope (LT), a fully robotic 2-metre astronomical observatory located at the Roque de los Muchachos Observatory, La Palma, Spain. The Liverpool Telescope has operated successfully for over twenty years and is a key scientific facility supporting UK-led astronomical research. LJMU is exploring options to modernise the telescope´s control systems and associated infrastructure to extend operational life, improve reliability, reduce maintenance burden and enhance scientific performance. The current scope under consideration includes: • Replacement and modernisation of the Telescope Control System; • Replacement of azimuth, altitude and Cassegrain axis drive systems; • Modernisation of enclosure control systems (PLCs software and control cards); • Replacement or redesign of selected optical and mechanism control systems; • Associated control system networking, timing and safety interfaces; • Design, manufacture, installation, testing, commissioning and post-upgrade support service; • Knowledge transfer, documentation and training.
