Stages of development of the ison optical telescope global network

ISON project had few stages of new tools and methods development to monitor the space debris. Firstly the obsolete telescopes that remained since the USSR were used. Then the 22-cm telescopes with FOV 4x4 deg. that could survey the entire visible part of the GEO were installed to maintain a catalogue of bright GEO-objects. Then the 19.2-cm telescopes with FOV 7x7 deg. were and the extended surveys were elaborated increases the orbit accuracy orbits for bright GEO-objects by obtained long tracklets. To detect HEO-objects the 2-tube and 4tube systems were produced for Roscosmos observatories, with FOV 9x7 and 9x14 deg. Separation of Roscosmos and industry organizations segments caused to the refreshed ISON network for scientific and commercial activities under the auspices of Small Innovation Enterprise “KIAM Ballistics-Service”.
