Interagency International Scientific Optical Network (ISON) represents one of largest systems specializing in observation of space objects. ISON provides permanent monitoring of the whole GEO region, regular surveying of Molniya type orbits, and tracking of objects at GEO, GTO, HEO and LEO. Currently ISON cooperates with 43 observation facilities of various affiliations with 100 telescopes in 17 countries. Six telescope subsets have been completed to the date, ISON encompasses five groups of telescopes and three scheduling centers. Obtained measurements are processed at the KIAM ballistic center to be used for scientific and applied goals, including collision risks analysis and space situation analysis. 20 millions measurements in 2.58 millions of tracklets for more 6740 objects have been collected by KIAM in 2016.
Search and study of the space debris and asteroids within ISON project
Anais da Academia Brasileira de Ciências
International Scientifi c Optical Network (ISON) is an open international voluntary project specializing in observations of the near-Earth space objects. Observatories collaborating with ISON provide the global coverage and successfully combine the observations of the space debris and asteroids. The network includes more than 50 telescopes of 27 observatories in 15 countries and has been working since 2005. ISON monitors the whole GEO region and tracks the objects at GEO, GTO, HEO and LEO. ISON data allowing maintenance of the database of the space objects orbits, validating space debris population model and providing conjunction assessment analysis for satellites at high orbits. ISON develops the technology of asteroid survey with small telescopes and arranges regular photometry observations of near-Earth asteroids (NEA) to investigate the YORP effect, search new binary NEAs, and support radar experiments.
Faint High Orbit Debris Observations with ISON Optical Network

New cooperation for global monitoring of space objects at high orbits, International Scientific Optical Network (ISON), is appeared under auspices of the Keldysh Institute of Applied Mathematics of the Russian Academy of Sciences. ISON provides the observations of faint deep space debris in cooperation with team of the Astronomical Institute of the University of Bern (AIUB) since 2004. It is

Optical observations represent a passive method for space debris tracking and monitoring. Although being constrained to limited time intervals, e.g. when the target is in sunlight and the observatory is in darkness, a debris observatory network distributed over multiple locations can improve the observational interval and favor the data integration for more consistent and significant results. The Sapienza Space Systems and Space Surveillance Laboratory (S5Lab) At Sapienza University of Rome has established Sapienza Space debris Observatory Network (SSON), an international network of optical observatories addressed at debris surveillance. The network is composed of six observatories owned and controlled by Sapienza, plus five observational sites controlled by collaborators (mainly University of Michigan and the University of Bern). The network operations have been carried out during several observations campaign, including the Tiangong-1 space station re-entry campaign performed in support of the Inter-Agency space Debris Committee (IADC). The heterogeneous capabilities of the different observatories represent an advantage for acquiring a wider set of debris monitoring data with different techniques. A strong synergy between our institution and the Italian specialized industry has also revealed to be very productive in the context of the network establishment. The present paper will describe the SSON infrastructure and the opportunities, improvements and future perspectives for research institutions or space industry of this wide observatories network will be discussed.
ISON Worldwide Scientific 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...
An increasing number of space junk in orbit has raised their chances to fall in Indonesian region. So far, three debris of rocket bodies have been found in Bengkulu, Gorontalo and Lampung. LAPAN has successfully developed software for monitoring space debris that passes over Indonesia with an altitude below 200 km. To support the software-based system, the hardware-based system has been developed based on optical instruments. The system has been under development in early 2014 which consist of two systems: the telescopic ystem and wide field system. The telescopic system uses CCD cameras and a reflecting telescope with relatively high sensitivity. Wide field system uses DSLR cameras, binoculars and a combination of CCD with DSLR Lens. Methods and preliminary results of the systems will be presented.
Optical Surveys for Space Debris in MEO
2012
The Medium Earth Orbit (MEO) region becomes increasingly populated as new navigation satellite constellations are deployed or existing constellations are replenished with new satellites. As a consequence a growing number of space debris including small-size objects must be expected. Based on the findings for the GEO and the GTO region this debris may consist of small-size mission related objects, delamination debris from aging spacecraft and upper stages, as well as fragments from breakup or collision events. None of the orbital planes of the existing or currently built up constellations like GPS, GLONASS, Beidou-2/COMPASS, and GALILEO has been systematically investigated for potential space debris so far. The Astronomical Institute of the University Bern (AIUB) performed several survey campaigns between January 2010 and November 2010 to search for debris objects in the MEO region. The optical observations were performed in the framework of an ESA study using ESA’s Zeiss 1-m telesco...
Space Debris Observations with ZimSMART European Space Surveillance Conference 7-9 June 2011
2011
The Zimmerwald observatory, located about 10km South of Berne (Switzerland), consists of several optical telescopes. One of them, the Zimmerwald SMall Aperture Robotic Telescope (ZimSMART) is best suited for surveying the sky searching for space debris. ZimSMART is used to develop an orbital elements catalogue, i.e. without any a priori information. Two different orbital regions are surveyed: the geostationary ring (GEO) and the Medium Earth Orbit region (MEO). The aim of the surveys of the geostationary ring is a coverage of as much as possible around the celestial equator we can observe from Zimmerwald. Surveys of the MEO region will give a first hint about the population of large-sized, uncatalogued space debris there. In this paper we will present observation strategies of ZimSMART for building up such a catalogue. The observation strategy for the MEO region differs significantly from that of the GEO region, due to the unique properties of each region. We will discuss survey res...
ISON's sub-network of small aperture telescopes for observations of NEOs, space debris and meteors
2019
ISON (International Scientific Optical Network) is one of the worldwide largest cooperations of observatories specialized in observations of satellites, space debris and minor bodies of the Solar System. Every year there is a considerable number of bright NEOs. To study this category of NEOs ISON plans to organize a broad subnetwork of over 25 telescopes with apertures of 22-25 cm which are primarily used for observations of satellites and space debris. The objective of this endevour is to guarantee observation results during the short flyby period of a NEO. The results of preliminary test observations have shown that these telescopes fully meet the task needs. At the ISON-Castelgrande Observatory a pilot project is in preparation for optical and radio observations of fireballs and meteor showers.
