Main actors in astronomy research in the country  There are 7 Research Institutes in the structure of the National Academy of Sciences of Ukraine (NAS of Ukraine), 2 Research Institutes in the structure of the Ministry of Education and Science, Youth and Sport of Ukraine (MESYS of Ukraine); 15 astronomical observatories and Departments in the structure of the Universities of the MESYS of Ukraine; 1 Private Astronomical Observatory play a main role in the development and teaching Astronomy in Ukraine.
The XPM Catalog  Absolute proper motions of 280 million stars distributed all over the sky without gaps in the magnitude range 10m < V <20m on the basis of combined data from 2MASS and USNO-A2.0 catalogues.
MAO NASU Plate Archive   Digital archive of MAO NAS of Ukraine (GPA) comprises data of about 26 thousands of direct photographic plates, obtained with 14 instruments in 9 observational sites, and more than 2000 digital images of different resolution available via GPA search pages.
Mykolaiv AO Plate Archive   Digital archive of Mykolaiv Aastronomical Observatory (MykAO) includes astronomical data obtained during observations with photo plates and CCD frames. The digitization of the archive is near its completion. Digitized images are available via a web browser and Aladin.
AO LNU Plate Archive   Astronomical Observatory of Lviv National University (AO LNU) is the owner of valuable archive that stores approximately 8 000 of photographic plates from 1939, including nearly 6 000 direct images of the northern sky. The archive is partly digitized and images are available via the joint search pages of AO LNU and MAO NASU.
IRA UTR-2 catalogue of RS   The very-low frequency sky survey of discrete sources has been obtained in the Institute of Radio Astronomy of the Ukrainian National Academy of Sciences (Kharkov, Ukraine) with the UTR-2 radio telescope at a number of the lowest frequencies used in contemporary radio astronomy within the range from 10 to 25 MHz.
Mykolaiv AO stellar catalogues   27 astrometric stellar catalogues of Mykolaiv Aastronomical Observatory (MykAO) in VOTable format are available for downloading
AO KNU Historic Plate Archive   AO KNU glass collection contains about 20 thousand photographic plates. Historical part of the archive was received during 1898-1946 and now is being digitized.

GRID-based Virtual Observatory VIRGO.UA 
VO VIRGO.UA for cosmology and astrophysics is a segment of VO «Infrastructure»- a virtual organization, which deals with ensuring the provision of standards for Grid Services for virtual organizations, to ensure reliability functioning of the Ukrainian power grid, Grid training for users and administrators of the Grid sites, as well as the creation of technical conditions UNG for entry into the international grid community...
WDC-Ukraine is a part of World Data Center System of the International Council of Science (ICSU). Among the basic tasks of WDC-Ukraine there is collection, handling and storage of science data and giving access to it for usage both in science research and study process. That include contemporary tutoring technologies and resources of e-libraries and archives; remote access to own information resources for the wide circle of scientists from the universities and science institutions of Ukraine...

US VAO Data Discovery Portal 
Find datasets from thousands of astronomical collections known to the VO and over wide areas of the sky. This includes important collections from archives around the world. Feedback on your experience with the tool is appreciated -- please send your comments, suggestions, and questions to the VAO Help Desk.
US VAO Cross-Comparison Tool 
Perform fast positional cross-matches between an input table of up to 1 million sources and common astronomical source catalogs, such as 2MASS, SDSS DR7 and USNO-B. Feedback on your experience with the tool is appreciated -- please send your comments, suggestions, and questions to the VAO Help Desk.
VOPlot v1.8 Beta 
VOPlot v1.8Beta includes many enhancements and bug fixes. To name a few v1.8Beta supports multi-grid plots for 2D Scatter-Plot which allows the user to have multiple plots having grid size from 1x1 to 3x3 in a single window. Paginated view is added to see data in tabular format which allows user to navigate systematically. Provision to label Lat/Long lines is also added. Users can now plot a cumulative histogram for all histogram types. VOPlot 1.8Beta shows the metadata of a FITS file instantaneously while the actual loading happens in background. VOPlot v1.8Beta also provides better handling of "faulty data" while parsing an ASCII file.

A number of UkrVO development primordial projects in the frame of its conception was defined and among them there is a creation of Joint Digital Archive (JDA) of data, storaged on different carriers in Ukrainian observatories. They are a) photographic observations of celestial objects in 1898-1990; b) CCD observations of celestial objects since 1990-th, c)spectral observations (including glass archives) in optical, UF, radio and gamma ranges since 1940-th. Most of them are now presented as Local Data Archives (LDA) with different level of systematization. Most of LDA has no online access.

The most important resource of JDA is archives of astronegatives, i.e. glass libraries. Astronomical observatory of Odessa National University (AO ONU) and MAO NAS of Ukraine (Golosiiv archive, GPA) are the owners of the greatest glass collections. AO ONU archive with 105 thousands of plates is the third in the world after Harvard and Zonnenberg archives and GPA includes more than 80 thousands of negatives. The unique observational collection is storaged in Crimean Astrophysical observatory (CrAO). The information capacity of this archive can be estimated only approximately - more than 60 appliances were used having been combined with more than 30 telescopes during 100 years of observations, which were carried out not only in in optical, but radio, UF and gamma ranges.

JDA of astronomical observations is created in order to join previously formatted in accordance with common input data standards LDA. The necessity of introducing such standards is conditioned by essential geterogeneity of observational data and the different level of LDA readiness for including into the JDA. Databases of JDA are to be integrated on the UkrVO site in the form of search interfaces and means of access to distributed servers of observatories - participants of UkrVO project where the LDA are physically located. The access to data from UkrVO site is to be opened according the LDA readiness and meeting the common standards. As JDA data are standartized then access to them can be realized through different interfaces and applications, developed in the specified observatories. In particular, as the test prototype of above said control mechanism joint data of MAO NASU and Mykolaiv observatory are available throuh search pages of both observatories.

Currently developed JDA informatic system is intended to include tools for UkrVo registry and joint/interconnected databases control and administration, user oriented search interfaces, online services for data analysis and processing, teaching software for VO tools application in scientific researches, the deployment of pan-Ukrainian infrastructure of observational data transmission into the internet, as well as means of itself development and other participants and scientific projects involving into the UkrVo activity.
