The U.S. Department of defense on may 1, 2020 will announce a tender for the development and deployment of a satellite network exchange data, which will be applied to a mesh topology. As writes C4ISRNET, winners of the tender it is planned to choose in August, and in the summer of 2022, the army intends to launch the first segment of a network consisting of 20 spacecraft.
A data exchange network built on a mesh topology implies that each individual member of the network can connect with other participants and to take on the role of the switch. Thus the network is devoid of specific control nodes. It provides high fault tolerance — the failure of one member does not violate its integrity and flow of information.
Cellular satellite network of the Pentagon will consist of satellites in low earth and geosynchronous orbits. These satellites will provide the military on the ground data with various intelligence satellites. To communicate with each other, the satellites will be through the optical terminal.
The network will be built in three phases, the first of which it will comprise 20 satellites in 2022. The second phase will be launched in 2024, and the third in 2026-m. the Exact number of connected devices has not yet been determined, but Pentagon officials say it will include several hundred satellites.
After completing the first stage of formation of the wire mesh military intend to hold its demonstration tests. On these tests it is planned to test the transferability of the intelligence of ground units with minimal delay, data transmission from the satellite to the satellite by means of an optical terminal, and limited combat control.
In addition, it will be verified the possibility of data transmission communication system standard Link-16 real-time and relay the data. In the future, the U.S. military expects to use cellular satellite network in a multi-domain operations.
The Pentagon introduced the concept of multi-domain military action in 2016. It involves coherent and precise part in the hostilities at the same time different kinds and types of troops from the Navy and air force to cyberarmies and Space command. The military believes that in case of war, this approach will allow you to defeat a high-tech enemy.
Today, the coordination of all available in the armed forces branches of the armed forces is extremely complex, and because in the case of a real war are often all sorts of errors, lining and the backlog in the time frame.
