On the demonstration satellite "Skif-D" created by the Academician M.F. Reshetnev Information Satellite Systems Company (part of Roscosmos State Corporation), the Russian equipment was flight qualified and the spacecraft control and Internet access technologies were tested.
The maximum speed of data transmission via "Skif-D", which was achieved during communication sessions, amounted to 6.5 megabits per second.
"Skif-D became a technology demonstrator of the future broadband Internet access system. It is designed to test new technical solutions and protect the orbital-frequency resource. This is the first device of the federal project "Sphere", which is aimed at eliminating the so-called "digital inequality": providing access to the Internet via satellites where it is impossible to lay fiber optic cables. For example, in high latitudes, taiga, tundra and permafrost zones.
The satellite was launched into orbit on October 22, 2022. It solved the task of protecting the orbital-frequency resource of the Skif satellite communications system. According to the rules of the International Telecommunication Union, radio-frequency applications must be confirmed again in October 2024.
