The mathematical model of distribution the means of radiomonitoring for observation data channels of satellite communications systems had been performed for consideration. The model is a formalizeddescription of the distribution process using mathematical... see more

In recent years, widely developed the concept of network-centric war (NET-CENTRIC WAR OPERATIONS, NCWO), the essence of which is to combine the sensor and combat subsystems to enhance the speed and control to ensure full synchronization of the f... see more

The results of analysis of methods of the special satellite lines from the radio electronic suppression are presented in the article. It is considered some perspective directions of antijamming of the satellite communication systems for example of three s... see more

Microwaves are used to communicate with satellite and terrestrial communication networks. But as microwaves pass through the Earth’s atmosphere, the oxygen gas absorbs microwave. In this 5G era, when the whole world is moving towards high data-rates and r... see more

It is known, when using narrow-band signals in high orbital satellite communication systems for organizing exchange of information, the efficiency of allocated frequency and time communication channel resource usage is reduced due to the large uncertainty... see more

This work studies the attenuation by rain that occurs in the Caribbean region, specifically, in high frequency bands, considering that modern communication systems make greater use of satellite bands. In this sense, the methodology of the recommendation I... see more

A versatile Propagation Simulation Program (PSP) is developed to assess the degrading effects caused by the concurrent occurrences of an arbitrary mixture of ice plates and needles, melting snow and raindrops which may impede the reliability of dual-polar... see more

Optical wireless communication offers high data rates applications due to license-free and wide-bandwidth access techniques and cost-effective implementations. Recently, the world introduced to a revolutionary technology called Inter-satellite optical com... see more
