30th Annual Report 2017-18

153 TMT TCS team including members from Honeywell, IUCAA and TMT Project Office. TMTTelescope Control System The Thirty Meter Telescope (TMT), a segmented mirror telescope with a 30-metar filled aperture, will be the world's most advanced ground-based telescope operating at optical and infrared wavelengths. An international consortium of institutions in the USA, Canada, China, Japan and India is building the telescope. About 70% of India's contribution to the construction of TMT will be in-kind. India's work share consists of both hardware and software. In software, India-TMT is responsible for delivering the Observatory Software (OSW) andTelescope Control System (TCS). The TCS is responsible for the coordination and control of various telescope subsystems. India-TMT is responsible for taking TCS through various project phases, i.e., (1) the Preliminary design (2) the Final design (3) the Code and Test (4) the Integration and Test, and finally, (5) theAssembly, Integration andVerification at the telescope site. IUCAA, on behalf of India-TMT, is responsible for delivering the TCS to the TMT International Observatory (TIO). In April 2016, the contract for the first phase of the project was awarded toOaces - HoneywellAutomation India Limited. In December 2016, the TCS team that consisted of engineers and scientists from Honeywell, IUCAA and TMT Project Office successfully completed the first phase of the project. As part of this phase, the TCS team successfully delivered (1) Design of the Hardware Control Daemon (HCD) that interfaces between the TCS and the Mount Control System (MCS) of the telescope, (2) MCS
