Программа "Авиатор" брала интервью у Агапова (возможно даже про нашу сеть будет пара слов) и у Иванова (начальник ЦУП ЦНИИМАШ) - готовят передачу про космический мусор, в предверии 12 апреля

2.2 Keldysh Institute for Applied Mathematics (KIAM)

This source provides orbital data derived from ground-based optical observations. Data are provided only for objects for which no USSTRATCOM TLEs are published. Orbits given in this report are produced from measurements obtained in 2016 and prepared by Vladimir Agapov, Keldysh Institute for Applied Mathematics, Moscow (KIAM). They are a joint product of the wide cooperation of organizations including:

• Center on collection, processing and analysis of information on space debris at the Keldysh Institute of Applied Mathematics of the Russian Academy of Sciences (KIAM RAS, Moscow, Russia),

• International scientific observation facilities network (ISON) coordinated by KIAM RAS and including the following observatories:
– Ussuriysk Astrophysical Observatory of the Far East branch of the RAS (Gornotayozhnoye, Primorsky Krai, Russia),

– Derenovka observation facility of Laboratory of space researches, Uzhhorod National University (Zakarpats’ka oblast, Ukraine),
– Chuguyev observation facility of the Astronomy scientific and research institute of Kharkov national university (Kharkiv’ska oblast, Ukraine),
– Cosala observation facility of the The Autonomous University of Sinaloa (Universidad Autonoma de Sinaloa, UAS, Mexico),
– Khureltogoot observatory of the The Research Centre of Astronomy and Geophysics of the Mongolian Academy of Sciences
– Observatory ”Peak Terskol” of the International Center for Astronomical, Medical and Ecological Research (Kabardino-Balkaria Republic, Russia),
– E.Kharadze Abastumani Astrophysical Observatory of Ilia State University (Abastumani, Adigeni District, Georgia),
– Mul’ta observation facility (Altai Republic, Russia),
– Observatory of Altai State Pedagogical University (Barnaul, Altaisky Krai),
– Observation facility of El Centro de Investigaciones de Ciencias Fisico Matematicas de la Universidad Autonoma de Nuevo Leon (UANL).

• Astronomical Institute of the University of Bern, partner of ISON, operating the Zimmerwald observatory (Switzerland) and, for space debris observation, the ESA 1m telescope at the optical ground station (OGS), Izana, Tenerife, Spain

• Telescope Fabra ROA Montsec (TFRM) operated by the Reial Academia de Ciencies i Arts de Barcelona - Observatori Fabra, the Real Instituto y Observatorio de la Armada (ROA) and the Departament d’Astronomia i Meteorologia, Universitat de Barcelona, Spain.

The objects for which ephemeris was provided by KIAM were observed repeatedly by ground based telescopes. They were listed in issues 7 to 13 as ’Unidentified objects’. During the years 2011-2015 most of them were correlated to a launch thanks to the excellent work of satellite analysts and amateur observers. A source id (S-ID), consisting of a label and number, is given for each such object in order to correlate it with itself from an earlier report.

ВА рекламу себя таки вставил Рука-Лицо

И неправильно расшифровал название нашей сети: Псих

• International scientific observation facilities optical network (ISON)

Не упомянуты Архыз, Абрау-Дюрсо, Научный-2 (ГАИШ), Научный-3 (Роскосмос, где стоит 50-ка) и пункт Вымпела в Москве.

GMV provides critical support to METEOSAT-7 end-of-life operations with optical telescopes

Meteosat-7 was launched in September 1997 and is operated by EUMETSAT, the European Organisation for the Exploitation of Meteorological Satellites. It is the last satellite of the first generation of Meteosat.

First over Europe and next from its current orbital location over the Indian Ocean region at 36000 Km above our heads, it has been providing a fruitful service for almost two decades, a period that is now coming to an end.

To avoid the proliferation of space debris in the crowded geostationary ring, EUMETSAT will conduct a safe re-orbiting into a so-called “graveyard” orbit, located at least 250 km above the current location. These end-of-life operations will be carried out in compliance with the latest recommendations included in the 24113 standard of the International Organization for Standardization (ISO) concerning space debris mitigation.

The re-orbiting will be performed starting on 3 April 2017 and by means of successive maneuvers, every half day approximately. Nominally after the first three maneuvers, the orbit will be raised already above the ISO protected ring. The orbit maneuvers will also be used to spin-down the satellite and dissipate its kinetic energy. The satellite will continue performing further maneuvers, with the same periodicity, until all remaining on-board fuel will be finally exhausted. Just after that, in less than one week, Meteosat-7 will reach its final “graveyard” orbit from the geostationary ring and it will be passivated.

In order to support these critical operations, GMV will task observations from 9 different telescopes worldwide to follow the spacecraft trajectory evolution every night. These telescopes, operated by GMV’s partner ISON (International Scientific Optical Network), are placed in distant locations in 6 different countries to ensure the highest redundancy in case of bad weather conditions or contingencies.

The data collected will be processed and delivered on a daily basis, to cope with the EUMETSAT augmented monitoring needs. This data will be used in support of operational tracking, based on regular ranging from the EUMETSAT ground stations network. This will ensure the highest reliability of the two major processes involved in this monitoring activity: the orbit determination process (ranging and optical data used singularly, or with data fusion technique) and the restitution/calibration of the executed maneuvers, both to be carried-out during these critical operations.

As part of this activity, and in parallel with these operations at EUMETSAT, GMV will make use of its internal state-of-the-art flight dynamics tools to perform an independent checking and monitoring of the maneuvers and orbital evolution of the spacecraft. GMV solutions, making use of all telescopes and ranging stations involved, will verify the correctness of EUMETSAT operational data.
