What is GISS?

Resolving the international problem of the shortage of the orbital-frequency resource allocated for telecommunication services through the joint cognitive use of the frequency range allocated on a primary basis for radar sensing of the Earth and radar. The 625 MHz X-band and 85 MHz L-band bands could be added to the orbital-frequency resource allocated for satellite communications, which will be reused in each of the service areas about 5000 km in diameter on the Earth’s surface.
In a technologically simpler and more developed range, in comparison with the Ku- and Ka-bands, GISS allows the provision of telecommunication services with higher rates of information exchange compared to geostationary satellite communication systems, and lower tariffs due to the dual use of spacecraft (SC) GISS and for Earth sensing radar services with various defense applications. The achievable technical characteristics of communication services in the GISS are given in section 2.
The provision of personal satellite communication services and broadband Internet access from one type of gadget that ensures operation in both 4G (5G) cellular networks and in GISS will be in wide demand for sparsely populated and underdeveloped regions of Russia, Mongolia, Indo-China, the Middle East, and South-East Asia, Africa and many regions of the continents of Asia and South America, the Arctic and Antarctica.
Precise indicators of the possible profit and payback of the project for the creation of GISS from the provision of a wide range of telecommunications services are now difficult to do. The slides (Fig. 3.22–3.24) for reference show some estimates and comparisons that suggest their high competitiveness in this market.
Prospects of providing communication services through GISS to passengers of long-distance passenger trains, cruise ships, air liners in flight and river vessels, as well as for reporting stations of television companies are beyond real competition even with Elon Musk’s Starlink project.
