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!!! ?
