18 July 2014 OCS: towards a more efficient telescope
Author Affiliations +
The OCS1 (Observation Control System) is a software architecture that allows automatic observations at the TNG2 (Telescopio Nazionale Galileo). It plays a critical role as it is responsible for orchestrating several devices and going through several heterogeneous software interfaces across the telescope. One successful key aspect of the OCS is the interface decoupling over the telescope devices in order to reach a high grade of automatism. The OCS architecture was successfully developed and installed at the TNG just before the arrival of HARPSN3 (more than 2 years ago) and has now reached a good level of maturity and flexibility. Using standard protocols like HTTP which allows a quick integration with new instruments and devices. At the beginning, when only two systems were connected to the OCS the HARPS-N scheduler and the TNG tracking system, other systems have been added to include more features, for example the service offered by the Active Optics system.
