Current Status and Developments of the ISON Optical Network

2009

The international scientific optical network (ISON) tha t was developed in the last few years is one from largest system specialized on space debris observations at high orbits and is able to observe whole GEO ring. Now ISON collaborates with 25 observatories in 9 countries. Series of standard telescopes and mounts was produced, and a lot of the modern CCD cameras is purchased to equip the ISON observatories. Standard solution for precise time keeping is installed at each telescope together with standard software packages for CCD frame processing, CCD camera, GPS receiver and mount control. 32 telescopes with aperture in range between 0.2 and 2.6 m are arranged in the three ISON subsets dedicated to different class objects. The ISON observations are coordinated mainly by the Center on collection; processing and analysis of information on space debris (CCPAISD) developed and operated on the basis of the Ballistic Centre at the KIAM, Russ ian Academy of Sciences. Almost one million me...

2015

In 2015 quantity of telescopes of 37 observatories that collaborate with ISON project in 17 countries is close to 100 units. These telescopes are combined in 4 main subsystems - for GEO survey, bright and faint objects follow up, and for asteroids (ASPIN). KIAM collected 10.7 million astrometry measurements during 2014 and 9.7 millions to the middle of September 2015. Since 2010, ISON is involving in operations of the Roscosmos Automated system of warning on dangerous situations in space (ASPOS OKP). In this system KIAM is responsible for the daily conjunction analysis at high orbits. To improve the quality of this activity ISON is deploying additional subnetwork for extended GEO surveys from 7 small (18-19.2 cm aperture) automated telescopes with field of view 7x7 degree. Extended surveys of new ISON subnetwork allows to KIAM to determine more precise GEO orbits, to detect maneuvers of active satellites and to help maintain the orbits of GEO objects in clusters. Also it was attempt...
