Short overview of activities performed under Roscosmos and RAS auspices in 2014 in the area of space debris monitoring Nikolay Sakva, Vladimir Agapov, Igor Molotov Roscosmos delegation Presentation for the WG1 session 33 nd IADC meeting, Houston

Works that are performing under the ROSCOSMOS auspices Development and operation of ASPOS OKP (Automated system of warning on dangerous situations in outer space) Main information and analytical center of ASPOS at TsNIIMash Segment of the system at Keldysh Institute of Applied Mathematics of the RAS responsible for monitoring GEO, HEO and MEO regions Segment of the system at TsNIIMash responsible for coordination with Russian space surveillance system operating by the Russian Aerospace Defence Forces Segment of the system at Pushkov Institute of the Earth Magnetism, Ionosphere and Radio Wave Propagation of the RAS Dedicated optical observation facilities Works that are performing under the RAS auspices Development and operation of ISON (International Scientific Optical Network) Construction of a new 1.6 m AZT-33VM telescope at Mondy have been continuing (jointly with Roscosmos) 33 rd IADC, Working Group 1 – Activities in Area of Space Debris Monitoring in 2014

33 rd IADC, Working Group 1 – ROSCOSMOS/RAS Activities in Area of Space Debris Monitoring in 2014 (2) ASPOS OKP New dedicated space debris observation optical facility (EOP-1) started regular operations since Apr 2014 at Byurakan observatory (Armenia): 2x19 cm, 1x25 cm, 1x40 cm There were 4 dedicated optical facilities with 11 telescopes operational as of the end of 2014 within the framework of ASPOS OKP: Kislovodsk (EOP-1: 2x19 cm, 1x25 cm, 1x40 cm; standalone 50-cm telescope), Byurakan (EOP-1: 2x19 cm, 1x25 cm, 1x40 cm), Ussuriysk (65 cm telescope), Abrau-Dyurso (25 cm telescope) 2.2 millions of measurements have been collected Segment of the ASPOS at KIAM continued to monitor spacecraft launched within the framework of the Federal Space Program (GEO communication, meteo, data relay; GLONASS) and objects crossing their orbits, to maintain orbital database, to predict possible close conjunctions and assess their characteristics. Data are reported to the Main information and analytical center of ASPOS (operating at TsNIIMash) Update on recent and further developments will be given in special presentation

RAS activity Some resources of ISON were used in 2014 partially to support Roscosmos tasks (ASPOS OKP), partially to support scientific studies at the Russian Academy of Science ~10.9 millions of optical measurements are collected during 2014 for ~3500 GEO, HEO and MEO objects (obtained by all facilities participating to the ISON project) 198 new high altitude objects absent in official U.S. STRATCOM list of catalogued objects are discovered in Jan-Dec 2014 and additional 58 objects – in Jan-Mar 2015 Regular dedicated HEO surveys (mainly for Molniya-type orbits) continued Special instruments operating by institutes of the RAS (Institute for Solar and Terrestrial Physics: AZT-33IK and AZT-14 telescope at Mondy; Institute of astronomy: Zeiss-2000 at Terskol, 50 cm telescope at Zvenigorod) were using for collection of photometric measurements and observation of the very faint objects 33 rd IADC, Working Group 1 – ROSCOSMOS/RAS Activities in Area of Space Debris Monitoring in 2014 (3)
