Publishing house URSS has issued the book "International regulations of radio communication services (in Russian), co-author (Chapter 8 "International Radio Monitoring System") and the editor of the whole book - IRCOS consultant, Dr. A.P. Pavlyuk.
This book covers the main provisions that regulate the use of radio frequency spectrum (RFS) by a number of Radiocommunication services on the international level, carried out by the national administrations through the International Telecommunication Union (ITU) in accordance with the decisions of World and Regional Radiocommunication Conferences and the rules of the Radio Regulations; through regional organizations involved in radio communications (European Conference of Postal and Telecommunications Administrations, Regional Commonwealth in the field of Communications, etc.), and other specialized organizations of the United Nations (International Civil Aviation Organization, International Maritime Organization, etc.). Despite of the fact that the focus is on the international regulation of Radiocommunication services, nevertheless, in some chapters of the book the experience of the Russian Federation is also described as a demonstration of the reflection of certain international provisions in the national regulations. For the first time in the national monographic literature for each of the Radiocommunication services the book considers at the system level a wide range of issues associated with the use of the RFS and ensuring electromagnetic compatibility of radio electronic means, which belong to the same service or to different services. A special value of this book gives a detailed consideration of the RFS use by specialized services that in so detailed format have not been done in the national publications before. This particularly concerns the international regulation of RFS by Maritime, Aeronautical, Scientific, Amateur radio services and Radio Astronomy, as well as the regulation of the International Monitoring System.
Information on the purchase of the book can be obtained by phone +7 499 7242545 or on the site http://URSS.ru.

An article “Virtual Antenna Array Theory and Applications” was published in “American Journal of Electromagnetics and Applications”. Vol. 3, No. 1, 2015, pp. 1-11.. The authors are research workers of IRCOS.
In this article the authors present a physical basis of virtual antenna array method which is based on electrodynamic principle of field source equivalence. It is demonstrated that the virtual antenna array method helps increase radio emitters angular coordinates accuracy by eliminating the error caused by scattering of initial wave on objects near “physical” antenna array. At this no data about antenna array carrier body geometry and material properties is required. Potential use of this method is also provided.

At this exhibition we will present for the first time a joint operation of ARC-D11 and AS-HP1 – a compact antenna system for direction finding within the range up to 3000 MHz.
- Finally we would like to demonstrate our measuring and instrumentation equipment: ARGAMAK-IM Panoramic Measuring Receiver and ARGAMAK-IS Panoramic Field Strength Meter. The latter unit has a unique design feature. It includes two separate modules – a signal digital processing module and a module comprising both receiving measuring antenna and a signal converter. This feature enables using the remote field transmitter for a distance up to 100 m from the digital processing module without loss of signal. At presentation, our measuring equipment will use SMO-BS1 software for GSM base station analysis.
