8 June 1995 TNG control system: computer architecture, interfacing, and synchronization
Author Affiliations +
TNG first light is foreseen for the latter half of 1996. Due to its main characteristics (alt- azimuthal mounting with tight pointing and tracking requirements, deformable primary mirror with active control, actively controlled secondary and tertiary mirrors), the computer support is essential, together with the need to command instrumentation and the possibility to operate remotely. Most of the control system has been developed and is now under test phase. The main characteristics of the computing environment are presented here. The implications of the desired performances on pointing and tracking are discussed and solutions to define the time base and synchronization are proposed.
