Short description: Lviv branch of the actual institute
LC ISR international relations

The Lviv Centre of the Space Research Institute of the NASU and NSAU (Ukrainian: Львівський центр Інституту космічних досліджень НАН України та НКА України) is a Lviv branch of the actual institute.

Structure

At the present about 100 specialists work in the centre. Among them 1 member of International Academy of Astronautics, 1 Doctors of Sciences, and 9 Candidates of Sciences (PhD).

LC ISR consists of 3 scientific departments and 1 laboratory, and performs fundamental and applied researches in the following interdisciplinary scientific directions:

  • propagation theory and experimental study of electromagnetic fields in conducting media such as plasma, ground, and sea water
  • development of advanced sensors and systems for measuring the parameters of physical fields and data collection and processing for space industry and geophysical applications.

Development and production of flux-gate magnetometers (FGM) and induction magnetometers (IM) with highest parameters values possible are of the main LC ISR activity areas.

Reduction of weight, energy loss and noise level can be placed among main directions of FGM and IM designing, which aims to reach world standards level. The center with its engineering divisions has made significant contribution into solution of large-scale fundamental and applied scientific problems, including:

  • development of theoretical substantiation of lithosphere-ionosphere coupling through the acoustic and atmospheric gravity waves with the aim to clarify mechanism of ionospheric earthquakes precursors formation;
  • development of the mechanism of earthquakes electromagnetic precursors recognition in focal area and designing specialized instruments for these precursors detection;
  • studying of electronic circuits interaction process with the aim to provide as low as possible sensitivity threshold of measuring devices for space, ground and sea bed applications;
  • development and adoption of new methodology to provide autonomous objects electromagnetic cleanliness, and to realize their calibration without operation process interruption;
  • adoption of space instrumentation development technology for manufacturing advanced geophysical systems, used for scientific research and raw materials prospecting (oil, gas etc.).

Significant scientific achievements and development

More than 10 spatial experiments were carried out with the participation of LC ISR specialists. LC ISR proposed scientific conception of the first national scientific experiment “Variant” (укр. Варіант) on the board of artificial satellite “Sich-1M” with international scientific payload.[1] For the first time in the world practice direct density of space current in plasma measurements were performed.

A generalized approach to the recognition of the precursory signals of earthquakes preparation process when structural changes and anomalies occur in the Earth crust was proposed.

A new physical effect – gamma – magnetic normalization of alloys with high magnetic permeability was discovered and experimentally confirmed.

A general concept and theoretical basis of the construction of a high-sensitive geophysical system for active electromagnetic logging in wells to study anisotropy of rocks and to detect the near-surface inhomogeneities were created with the aim to develop the new methods of minerals exploration.

The scientific concept and realization plan of the ground-spatial experiments “Ionosphere” and “Potential” were developed. Technical documents substantiating the above experiments were prepared. They were included in the National Space Program of Ukraine for 2013–2015 years.

Current projects

There are now 8 international space projects in which LC ISR is participating: OBSTANOVKA and CHIBIS-M [5] scheduled for International Space Station and RADIOASTRON (launch in 2010), PHOBOS-GRUNT (launch in 2011), RESONANCE (launch in 2012) – all of them with Russian scientists. Also LC ISR is collaborating with scientists: from India in the preparation of SENSE microsatellite scientific program and payload, Italy (ESPERIA project) and China (CSES microsatellite).

POPDAT

Problem-Oriented Processing and Database Creation for Ionosphere Exploration.[6] (started on June 1, 2011) [7]

Variant

The major goal of the VARIANT project onboard SICH-1M satellite is to carry out the study of field-aligned currents as a part of Space Weather program. It includes direct measurements of current density in the ionosphere combined with the measurements of the magnetic and electric field fluctuations that can serve as new elements in the data set of signatures of the solar wind-magnetosphere-ionosphere coupling. The secondary goal of VARIANT experiment is the statistical study of minor seismogenic effects in the ionosphere and their comparison with the background noise statistical data set (Presentation).

International Space Station environment study

LC ISR is Co-PI of the international experiment OBSTANOVKA-1 on board the Russian segment of the International Space Station (ISS). The main goal of the experiment is to develop the methodology and instrumentation for EM phenomena investigation in the ISS environment. To fulfil this goal the automatic mini-buoys and necessary operation procedures are under development.

Electromagnetic investigations at Ukrainian Antarctic Station “Akademik vernadsky”

Three-component flux-gate magnetometer LEMI-008 was installed in the Vernadsky Research Base "Akademik Vernadsky" is a Ukrainian Antarctic Station at Marina Point on Galindez Island in the Argentine Islands, Antarctica. In January 2001, the equipment for satellite transmission of magnetometer, which provides the communication via geostationary satellite GOES-E, was installed. On March 11, 2001, the permanent transmission of the LEMI-008 magnetometer data has started. The data are being cumulated on FTP-server after processing in the Canadian information center. Early in 2002 new high-sensitivity system for magnetic field 0.3–300 Hz variations based on LEMI-112A sensors has been installed. It expands the range of on-site EMF studies and sets Ukrainian Antarctic Station as one of the world's best equipped. LC ISR is responsible for the operation of electromagnetic polygon there.
