Growth of local area network Observatory associated with employee needs to access network resources has led to an increase in the number of computing and network devices. Until recently, we tested performance of these systems excellent manual and most of the problems and faults detected already on the fact the accident occurred. For a small number of network nodes, manual monitoring is not a significant problem, but with increasing the number of nodes troubles hooting becomes a very difficult task for network and system administrators and outage in work of network services Observatory may becomes critical. There fore there was a need to automate the monitoring service network resources and servers.

Astronomy ,QB1-991 - Abstract
Radioastron is the international project led by the Astro Space Center of Lebedev Phisical Institute. Moscow, Russian Federation. 10 m Space Radio Telescope is the main payload of Spektr-R spacecraft. It's designed by Lavochkin Association of Roscosmos Russia State Agency. The project goal is to create together with a ground based radio telescopes the huge Ground to Space interferometer with a baseline up to 350 km, to obtain images, positions and movements of various objects in the Universe with extremely high angular resolution (about 10e-6 arcsec). After successful launch on 18 July, 2012 the Radioastron missions starts systematic investigations of the Universe at broad radio frequencies range.

Astronomy ,QB1-991 - Abstract
Buffer data center was created in the territory of the Pushchino Radio Astronomy Observatory three years ago. The necessity of its creation was caused by the high requirements to the speed and quality of the transmission large amounts of scientific and telemetry data received by tracking station RT-22 from the space radio telescope of the international project “Radioastron”. The transfer of this data is carried out over a long distance over100 kmfrom the Pushchino toMoscowcenter of processing and storage ASC FIAN. And now we use the data center as a center of local network of the Observatory.

In this paper, questions on development, implementation, and operation of RadioAstron project Data Processing Center (DPC) are reviewed. The main components of the dedicated DPC are the computer complex with 1 TFlops/s performance, storage with memory capacity of approximately 10 PB, the network infrastructure, and the corresponding communication channels. Performance enhancement methods and resolution of information storage, archiving, and process problems of space VLBI high-speed digital data flows are analyzed. It is shown that successful operation of DPC is mainly provided by optimal organization of computer system structure, storage, and networking transmission. Some of the important key features of RadioAstron project DPC and its comparative differences from the standard VLBI procedures are considered.

The largest Key Science Program of the RadioAstron space VLBI mission is a survey of active galactic nuclei (AGN). The main goal of the survey is to measure and study the brightness of AGN cores in order to better understand the physics of their emission while taking interstellar scattering into consideration. In this paper we present detection statistics for observations on ground-space baselines of a complete sample of radio-strong AGN at the wavelengths of 18, 6, and 1.3 cm. Two-thirds of them are indeed detected by RadioAstron and are found to contain extremely compact, tens to hundreds of $\mu$as structures within their cores., Comment: Accepted to the Advances in Space Research special issue "High-resolution Space-Borne Radio Astronomy"

The space interferometer Radioastron is working jointly with the largest radio telescopes of the world. Ground tracking stations provide for retrieving the information and determining the orbital parameters for data processing centers. The project is aimed at systematic studies of images of radio emitting regions, their coordinates, and time-dependent variations near super-massive black holes in galactic nuclei, stellarmass black holes, neutron and quark stars, regions of star and planet formation in our and other galaxies, the structure of interplanetary and interstellar plasma, and the Earth’s gravitational field.

The Russian Academy of Sciences and Federal Space Agency, together with the participation of many international organizations, worked toward the launch of the RadioAstron orbiting space observatory with its onboard 10-m reflector radio telescope from the Baikonur cosmodrome on July 18, 2011. Together with some of the largest ground-based radio telescopes and a set of stations for tracking, collecting, and reducing the data obtained, this space radio telescope forms a multi-antenna ground-space radio interferometer with extremely long baselines, making it possible for the first time to study various objects in the Universe with angular resolutions a million times better than is possible with the human eye. The project is targeted at systematic studies of compact radio-emitting sources and their dynamics. Objects to be studied include supermassive black holes, accretion disks, and relativistic jets in active galactic nuclei, stellar-mass black holes, neutron stars and hypothetical quark stars, regions of formation of stars and planetary systems in our and other galaxies, interplanetary and interstellar plasma, and the gravitational field of the Earth. The results of ground-based and inflight tests of the space radio telescope carried out in both autonomous and ground-space interferometric regimes are reported. The derived characteristics are in agreement with the main requirements of the project. The astrophysical science program has begun., 54 pages, 11 figures; published by Astronomicheskij Zhurnal (in Russian) and Astronomy Reports (in English)
