6Internet connection of our division
7Problems
- 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
8Problems
- 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.
9Requirements
- 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
10Requirements
- Online catalogs and databases. Virtual
Observatory - http//archive.stsci.edu/
- Hubble Data Archive (HDA) 5.2 TB
11Requirements
- 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.
12Requirements
- 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.
13First permanent GPS network in Ukraine (NATO NIG
1999 - 2000)
Daily transfer 10 20 MB, but in 1h -gt need
min. 64 Kbps channels!!!
14Optical communication experiments with
geostationary satellite
15Telecommunication 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.
16ESA and MAO proposed common experiment V.Kuzkov,
M.Medvedskij, D.Yatskiv, V.Nedashkovsky,
Yu.Gluschenko, V.Suberljak, M.Peretytko,
N.Eremenko.
17Conclusions
We need a high band INET channels (gt 2 Mbps) in
all academic institutes for everyday
scientific work BUT without extra
payment!!! ?
