5481. The real-time system for astronomical observations on the telescopes of the
... The real-time system for astronomical observations on the telescopes of the virtual observatory from ICAMER, SAO RAS, and BNO INR RAS . ... 81K Three large astronomical observatories-- ICAMER, SAO and BNO JNR RAS- are located in the compact area of the Northern Caucasus. ... The unification and synchronization of data-flows from these telescopes will allow one to carry out astronomical observations at a new level and to realize a virtual observatory with new capabilities for space research. ...
