AT THE JUNCTION OF SPACE AND TELECOMMUNICATIONS LAW: SATELLITE ORBITS AND FREQUENCY REGULATIONS FOR NONGEOSTATIONARY SATELLITE SYSTEMS

V.A. Strelets, Radio Regulations Board of ITU, member, Ph.D.; vstrelets2000@mail.ru

It was shown that multi-satellite communication systems based non-geostationary satellite orbit require broadband allocations of radio frequency spectrum toensure electromagnetic ompatibility with space and terrestrial radiocommunication services. The historical review of the international regulations on the use of radio-frequency spectrum by satellite systems on non-geostationary satellite orbit (non-GSO) indicates that the period 1995-2000 was marked by innovative solutions both in technical and regulatory terms – ITU had developed regulations in a timely manner, assisting operators of non-GSO MSS and FSS projects to realize their plans. The main directions of the international regulations on the use of spectrum by non-geostationary satellite systems are being analyzed. It is noted that, because of the complexity of the non-GSO systems, the difficulties of interference simulation in the constantly changing environment, the operational features of such systems, another breakthrough is needed in the ITU-R studies, which expected to result in the adoption at the World Radiocommunication Conference in 2019 of international regulations governing the orbit-spectrum use by non-geostationary satellite systems.
Keywords: international space treaties, space, international regulations of orbit-spectrum use, Radio Regulations, geostationary and non-geostationary satellite systems.

International initiatives aimed at using information obtained through space activities for the prevention, mitigation of disasters and for relief operations are being considered. The international legal mechanisms for improving this activity are examined. It is demonstrated that the use of such space technology, as Earth observation, meteorology, navigation and telecommunication satellite systems, plays an essential role in prevention of natural and man-made disasters and reducing all the negative consequences caused by them.

AT THE CROSSROADS: THE OUTCOME OF THE 56 TH SESSION OF THE UN COPUOS LEGAL SUBCOMMITTEE

O.A. Volynskaya, Institute of International Economy and Finance, Russian Foreign Trade Academy of the Ministry of Economic Development of Russia, research assistant, LL.M in EU law, Ph.D.; o.a.volynskaya@gmail.com

The article presents a political-legal overview of the main results of the 56th session of the Legal Subcommittee (LSC) of the United Nations Committee on the Peaceful Uses of Outer Space and prospects for its future work. For more than half a century the LSC has been a unique international cooperation forum whose decisions determine the character of international legal regulation of all space activities undertaken by countries all over the world. In light of the recent weakening of the LSC’s role the initiative by certain states to stimulate, through national legal mechanisms, the development of private business in space is highly relevant. Such unilateral actions have served as a very timely and powerful incentive to provoke discussions in the LSC and paved the way for the Subcommittee to prove once again its competence in addressing the most acute problems of international space law.
Keywords: international space law, Outer Space Treaty, UN COPUOS, Legal Subcommittee, space resources.

A.E. Koucheryavy, The Bonch-Bruevich SPbSUT, head of department, Dr.Sci.(Tech.); akouch@mail.ru

The features of the 5G networks were analyzed. The 5G networks are considered as a base of the digital economy. The focus of the investigation is the network architecture, ultralow latency and Tactile Internet. Main conclusion of the study is the following: the deployment of the 5G networks with Tactile Internet realization leads to networks decentralization and de-globalization of the economy.
Keywords: 5G network, Tactile Internet, networks decentralization, de-globalization of the economy, digital economy.

APPROACH TO CONVERSION OF OVERLAY NETWORK QoS QUOTA SET TO A WIRELESS SENSOR NETWORK QoS QUOTA SET

A.A. Dvornikov, Higher School of Economics – National Research University, postgraduate student; advornikov@hse.ru

Approach to conversion of QoS quota set related to an overlay network to a quota set supported by a wireless sensor network is proposed. The approach allows to design software and hardware that provide services of overlay channels and overlay networks over a wireless sensor network. The main services running on a base network are unaffected. The approach illustrated by an emergency text message overlay network over LoRaWAN wireless sensor network.

The method of using parametric simulation for a choice of an optimal variant of creation of the radio engineering device (system) is considered. It is suggested to use the information approach for estimating the degree of coincidence of parametric models high productive preparation modules with the values of the parameters specified in requirements specification. The degree of coincidence is estimated by three criteria: informative, adequacy and accuracy. Estimation of informative and adequacy of parametric models is based on a comparison of the entropy obtained before and after covering the structural element of the radio engineering devices by the model of the corresponding module. The accuracy of the model is estimated by the deviation of the values of the parameters of the parametric models of high productive preparation modules from the values of the similar parameters of the corresponding structural element. It is shown that the suggested method allows to solve the problem of parametric synthesis of the effective structure of a radio engineering device.
Keywords: radio engineering devices, parametric simulation, high productive preparation modules, databases, electronic archive, information entropy, Unified system of design documentation.
