ABSTRACT: Recently, with the increasing impact of globalization, there has been a growing demand of ubiquitous and seamless connectivity all across the earth. With Internet of Things (IoT) applications coming to life with the 5G technology, a paradigm shift in communication network infrastructure has become unavoidable. In particular, leading technology firms making excessive investments in Low Earth Orbit (LEO) satellite communication networks and reusable launch vehicles, have made access to space more convenient and profitable and as a result, space-based communication, navigation and remote sensing services are generating new businesses and industries. In this talk, an introduction to satellite communication systems will be given and the reasons behind the growing trend of space networks of LEO satellites will be presented. The key technologies and main challenges for these networks will be summarized and well-known network solutions in the global market will be compared. Finally, the system solutions currently being developed in Satellite and Space Technologies Directorate at ASELSAN will be summarized.
