Distributed Framework for Dynamic Telescope and Instrument Control

摘要: Traditionally, instrument command and control systems have been developed specifically for a single instrument. Such solutions are frequently expensive inflexible to support the next development effort. NASA Goddard Space Flight Center is developing an extensible framework, known as Instrument Remote Control (IRC) that applies any kind of can be controlled by computer. IRC combines platform independent processing capabilities Java with power Extensible Markup Language (XML). A key aspect architecture software driven description, written using (IML). IML XML dialect used describe graphical user interfaces monitor instrument, sets formats, data streams, communication mechanisms, algorithms. The framework provides ability communicate components anywhere on network JXTA protocol dynamic discovery distributed components. (see http://www.jxta.org) generalized allows devices connected in peer-to-peer manner. uses advertise device?s discover interest network. Devices join or leave thus environment IRC. Currently, several astronomical instruments working team develop custom their instruments. These include: High resolution Airborne Wideband Camera (HAWC), first light Stratospheric Observatory Infrared Astronomy (SOFIA); Submillimeter And Far Experiment (SAFIRE), principal investigator SOFIA; Fabry-Perot Interferometer Bolometer Research (FIBRE), prototype SAFIRE at Caltech (CSO). Most recently, we Submillimetre Angular Resolution IInd Generation (SHARCII) CSO investigate SHARC instrument.© (2002) COPYRIGHT SPIE--The International Society Optical Engineering.
