New status of ISON - an open international project and database for space debris information exchange.

International Scientific Optical Network (ISON) was an open international scientific project specializing in observations of the near-Earth space objects. Started in Pulkovo observatory in 2004, ISON project then continued in Keldysh Institute of Applied Mathematics RAS (KIAM RAS), and is currently under dedicated company Small Innovation Enterprise "ISON Ballistics-Service" (SIE ISON-BS). With this goal SIE ISON-BS developed the observation scheduling centre and database. A new direction of project development was the arrangement of an international centre for the exchange of measurement and orbital information on space debris. SIE ISON-BS established an international exchange of data with a number of observatories, universities and scientific institutes. Therefore, although the number of observatories of the project has decreased to 22 (telescopes of SIE ISON-BS are now in 14 observation points and there are 8 partner observatories) the volume of measurements in the ISON database has grown few times. In 2022 ISON database received in average daily 120 thousand measurements and obtained to end of year over 45 mln. measurements in almost 5 mln. tracklets, and maintains the orbits of 10086 space objects (3122 GEO, 5267 HEO and 1697 MEO), from that 3226 are objects with high are to mass ratio (including 901 GEO, 1461 HEO and 864 MEO) on 01.09.2023. ISON carries out the scientific and commercial activities under grants and contracts with foreign organizations.
