Abstract:
The article describes the current state of the scientific network of optical instruments for astrometric and photometric observations. The analysis of results of observational network in 2017, including the comparison with other Russian observing cooperation, is given. We demonstrate that the ISON network continues to make a notable contribution to the task of maintaining the catalog of the precise orbits of large GEO-objects.
