Development of a phased array antenna powered by Rotman printed lens for a mobile satellite communication terminal

Connecting to the Internet whenever and wherever you travel is no longer a luxury. All people have the ability to connect to the Internet and share data away from home. Satellite communications are now an integral part of successful and high-quality communications. Satellite communications antennas are usually installed on mobile ground terminals. Due to its wide coverage and versatility, satellite communications are continuously improving and adapting to the telecommunications needs of many countries, despite the fact that broadband, Internet and fiber - optic communications are used almost everywhere. We know that more than 50 % of all satellites in orbit are communications satellites.

THE MAIN DIRECTIONS OF THE CONCEPT OF COMMUNICATIONS IN A LOW-ORBIT RELAY SATELLITES COMMUNICATION SYSTEM

Рассмотрены проблемы организации связи в системе персональной подвижной спутниковой связи (СППСС) на низкоорбитальных спутниках-ретрансляторах для обеспечения широкополосного доступа к сетям передачи данных с применением небольшого персонального абонентского терминала (АТ). Дан краткий анализ существующих СППСС, определены требования к системе связи,представлены основные направления организации информационного обмена,предложенорешение создания АТ. The paper is devoted to the problems of communication organization in the low-orbit personal mobile satellite communication system for providing broadband access to data transmission networks using a small personal subscriber terminal. A brief analysis of the existing systems of personal mobile satellite communications is given, the requirements for the communication system are defined, the main directions of information exchange organization are considered, and a solution for creating a subscriber terminal is proposed.

ASSESSMENT OF RUSSIA'S REAL NEEDS FOR MOBILE SATELLITE COMMUNICATIONS SERVICES

Приведена количественная оценка реальных потребностей Российской Федерации в услугах подвижной спутниковой связи на период 2021-2030 гг. Оценка выполнялась путем прямого подсчета численности потенциальных потребителей услуг в разных сферах народного хозяйства России, включая ее Арктический регион и Северный морской путь, с учетом возможностей реализации альтернативных спутниковым вариантов предоставления этих услуг. A quantitative assessment of the real needs of the Russian Federation for mobile satellite communication services in 2021-2030 is presented. The assessment was carried out by directly calculating the number of potential consumers of services in various areas of the Russian economy, including its Arctic region and the Northern Sea Route, taking into account the possibilities of implementing alternative economic options for providing these services.
