This article is devoted to reviewing the results of testing an electronic security seal. The electronic security seal is one of the main parts of Intelligent Transportation System Transit, intended to control the integrity and movement of cargo section of a carrier vehicle by means of the satellite navigation system, mobile cellular communication system and satellite communication system. The electronic security seal operates as remote, autonomous, outdoor used device, installed on the hinges of the cargo compartment doors. In this regard, the development of the electronic security seals is followed by tests to verify the desired characteristics and sustainability together with the resistance to external influences factors. Technical and operating characteristics of the electronic security seal were checked. Tests of the electronic security seal on resistance to such climatic factors as temperature and humidity were carried out. Tests of the electronic security seal on resistance to mechanical influences (vibration, mechanical shock) were performed.

Abstract This article reviews the transport traceability system for customs goods within the Eurasian Economic Union, which is the automated data system used to control integrity and movement of cargo section of a carrier vehicle by means of satellite navigation system, mobile cellular communication system and satellite communication system. Article is dedicated to the development of a model that simulates functions of transport traceability system for customs goods, which are being transported using the international transit transport corridors, and this model would be also used for assessment of a demand on electronic seals by seal installation stations, and for determination of correspondence between simulated transport route and actual travel time. Simulation model was already used in a test project, where it was integrated into “EVAC Transit” transport traceability system, and it has proven it’s operability and efficiency.

The technical aspects of the main promising projects in the segments of medium and low-orbit satellite communication systems are considered, as well as the project of the domestic low-orbit information and telecommunications system using the terahertz range, which is based on the use of satellite platforms of the micro- and nanosatellite class and the distribution of functional blocks of complex satellite payloads more high-end on multiple functionally related satellites. The proposed system of low-orbit satellite communications represents the groupings of low-orbit spacecraft (LEO-system) with the architecture of a "distributed satellite", which include the groupings of the root (leading) satellites and satellite repeaters (slaves). Root satellites are interconnected in a ring network by high-speed links between the satellites. The geometric size of the “distributed satellite” is the area around the root satellite with a radius of about 1 km. The combination of beams, which are formed by the repeater satellites, make up the service area of the LEO system. The requirements for the integrated service area of the LEO system (geographical service area) determine the requirements for the number of distributed satellites in the system as a whole. In the proposed system to reduce mutual interference between the grouping of the root (leading) satellites and repeater satellites (slaves) and, accordingly, minimizing distortions of the information signal when implementing inter-satellite communication, this line (radio channel) was created in an unlicensed frequency (e.g., in the terahertz 140 GHz) range. In addition, it additionally allows you to minimize the size of the antennas of such a broadband channel and simplify the operation of these satellite systems.

A single Radio-Frequency Interference (RFI) is a disturbance source of modern wireless systems depending on Global Navigation Satellite Systems (GNSS) and Satellite Communication (SatCom). In particular, significant applications such as aeronautics and satellite communication can be severely affected by intentional and unintentional interference, which are unmitigated. The matter requires finding a radical and effective solution to overcome this problem. The methods used for overcoming the RFI include interference detection, interference classification, interference geolocation, tracking and interference mitigation. RFI source geolocation and tracking methodology gained universal attention from numerous researchers, specialists, and scientists. In the last decade, various conventional techniques and algorithms have been adopted in geolocation and target tracking in civil and military operations. Previous conventional techniques did not address the challenges and demand for novel algorithms. Hence there is a necessity for focussing on the issues associated with this. This survey introduces a review of various conventional geolocation techniques, current orientations, and state-of-the-art techniques and highlights some approaches and algorithms employed in wireless and satellite systems for geolocation and target tracking that may be extremely beneficial. In addition, a comparison between different conventional geolocation techniques has been revealed, and the comparisons between various approaches and algorithms of geolocation and target tracking have been addressed, including H∞ and Kalman Filtering versions that have been implemented and investigated by authors.
