Title: Network requirements from Ukrainian Physics and Astronomy communities


1
Network requirements from Ukrainian Physics and
Astronomy communities
  • Dr. Peter Berczik
  • Main Astronomical Observatory
  • Ukrainian National Academy of Sciences

  4. Conclusions

3
Ukrainian National Academy of Sciences
30,000 scientific workers in 166 institutes
4
Physics and Astronomy division of Ukr. Nat. Acad.
of Sci.
7,500 scientific workers in 24 institutes
5
Institute profiles
  • Astrophysics, Cosmology (Prof. Yuri Izotov)
  • Geophysics (Prof. Yaroslav Yatskiv)
  • Space Physics (Dr. Vladimir Kuzkov)
  • High Energy Physics (Prof. Laszlo Jenkovszky)
  • Atomic and Nuclear Physics
  • Atmospheric and Oceanic Physics
  • Biological and Medical Physics
  • Chemical Physics
  • General and Classical Physics, Fluid Dynamics
  • Optics, Plasma Physics
  • Quantum Physics
  • Mathematical Physics

6
Internet connection of our division
7
Problems
  • Ukraine state budget 11 billion USD
  • Population 48 million
  • UNAS budget 75 million USD
  • Typical institute budget 450 k USD
  • Typical money for one scientists
  • 450 k USD/200/12 190 USD/month

8
Problems
  • No direct money for INET payments in academic
    budget!!!
  • No direct money for communication infrastructure
    development in academic budget!!!
  • The INET connection is a own problem of
    institutes, no have any free or centralized
    academic network services.

9
Requirements
  • INET for library services. The common everyday
    task.
  • http//xxx.lanl.gov/
  • 100 MB/day
  • ApJ, AJ, AA, MNRAS
  • 100 MB/day
  • http//ads.harvard.edu/
  • 100 MB/day

10
Requirements
  • Online catalogs and databases. Virtual
    Observatory
  • http//archive.stsci.edu/
  • Hubble Data Archive (HDA) 5.2 TB

11
Requirements
  • Other online catalogs and databases
  • The Digitized Sky Survey (DSS). The Catalogs and
    Surveys Branch of the STScI has been digitizing
    the photographic Sky Survey plates from the
    Palomar and UK Schmidt telescopes in order to
    support HST operations and provide a service to
    the astronomical community. Archive users can
    easily retrieve image data for any part of the
    sky.
  • The Sloan Digital Sky Survey (SDSS) is using a
    dedicated 2.5 m telescope and a large format CCD
    camera to obtain images of over 10,000 square
    degrees of high Galactic latitude sky in five
    broad bands (u', g', r', i' and z', centered at
    3540, 4770, 6230, 7630, and 9130 A,
    respectively). The first data release, planned
    for June 2001, includes imaging data containing
    a searchable catalog, images in several formats
    (FITS and JPEG), and spectra in both FITS format
    and GIF spectra with line identifications. This
    first public data release will contain over 500
    square degrees of sky.

12
Requirements
  • Other online catalogs and databases
  • The Far Ultraviolet Exporer (FUSE) covers the
    905-1187 A spectral region. This active mission
    contains high resolution spectra of hot and cool
    stars, AGNs, supernova remnants, planetary
    nebulae, solar system objects and the
    interstellar medium. The International
    Ultraviolet Explorer (IUE) Final Archive, which
    contains over 104,000 spectra of approximately
    10,000 individual astronomical sources (covering
    the 1,200 - 3,350 A range). The Extreme
    Ultraviolet Explorer (EUVE) Archive, which at
    present contains spectroscopic observations (in
    the 70 - 760 A range) of about 300 sources,
    mostly Galactic. The Ultraviolet Imaging
    Telescope (UIT) Archive, which contains 1,579
    images of 259 targets (covering the 1,200 - 3,300
    A range) obtained by UIT as part of the ASTRO-1
    and ASTRO-2 missions.
  • The Faint Images of the Radio Sky at
    Twenty-centimeters (FIRST) Archive. The FIRST
    project is designed to produce a radio survey at
    20 cm (1.4 GHz) of over 10,000 square degrees
    down to a flux of 1 mJy.

13
First permanent GPS network in Ukraine (NATO NIG
1999 - 2000)
Daily transfer 10 20 MB, but in 1h -gt need
min. 64 Kbps channels!!!
14
Optical communication experiments with
geostationary satellite
15
Telecommunication satellite ARTEMIS was launched
on 12 July 2001. He has RF channels and SILEX
device (Semiconductor Laser Inter Satellite Link
Experiment) worked at 2 Mbps and 50 Mbps rates.
ESA constructed the optical ground station at
Tenerife Observatory, Canary islands for ground
test of SILEX.
16
ESA and MAO proposed common experiment V.Kuzkov,
M.Medvedskij, D.Yatskiv, V.Nedashkovsky,
Yu.Gluschenko, V.Suberljak, M.Peretytko,
N.Eremenko.
17
Conclusions
We need a high band INET channels (gt 2 Mbps) in
all academic institutes for everyday
scientific work BUT without extra
payment!!! ?
