The problems of electromagnetic compatibility of satellite networks are among the most complex and sensitive issues dealt with by the International Telecommunication Union (ITU), which is the United Nations office in Geneva.
In Russia, literally 5 people understand the problem in all its details and can defend the interests of Russian operators - owners of satellites (artificial earth satellites) at the ITU level.
Therefore, I will give the floor to Boris Abramovich Lokshin. He stood at the origins of Russian direct broadcast television, known in our country as NTV-Plus, Tricolor, Orion, MTS-TV - they all came later and followed the previously laid track in technology ... Boris Abramovich has authority in the industry (very modest in life) just huge ..

Of practical interest for Russia is the issue of coordination between the British OneWeb and the domestic system with high-elliptical satellites Express-RV. The calculations of several authors have shown that without taking certain organizational measures, the joint operation of the two systems will be impossible, since both are planning to use overlapping frequency bands in the Ku-band. A reasonable solution seems to be the allocation of a part of the common frequency band to the British company with the obligatory requirement of reaching an agreement with the GP KS on sharing the frequency band.
A few words from me.
Separately, we can talk about OneWEB, which claims to have priority on Ku-band frequencies for LEO satellite systems. This is an old story about WorldVu, known to all as OneWEB, which believes that ITU previously granted WorldVu the rights to use the radio frequency spectrum (about 2 gigahertz Ku-band using non-geostationary satellites at altitudes between 800 and 950 kilometers. WorldVu believes it has inherited rights to the frequency spectrum of the SkyBridge company, created in the late 1990s, and wanted to use the Ku-band to provide communications services in low orbit.
SkyBridge went bankrupt in part due to the prohibitive cost of the satellites and ground terminals it needed. However, before SkyBridge went bankrupt and disappeared as a company, it had intensive negotiations with existing satellite operators in the GSO about whether dozens of SkyBridge satellites in low orbit (about 1,000 km) would interfere with telecommunications satellites in the 36,000 km geostationary orbit. over the equator.
ITU ultimately agreed (coordinated the frequencies) that SkyBridge could work to avoid interference to satellites in higher orbits using the same Ku-band spectrum by regularly adjusting its signal strength levels.
The allocation of the SkyBridge Ku-band spectrum by the International Telecommunication Union (ITU) did not go anywhere even after SkyBridge went bankrupt and was taken over by WorldVu, which bought out SkyBridge assets (and, accordingly, its rights to this spectrum). According to ITU regulations, WorldVu had time until 2020 to start deploying its satellites, which OneWEB successfully dealt with in August 2019, after which it issued this press release.
London, August 7, 2019 – OneWeb, whose mission is to connect everyone everywhere, is pleased to announce it has succeeded in bringing into use its spectrum rights in the Ku- and Ka-band spectrum.To achieve this milestone, OneWeb’s satellites have been transmitting at the designated frequencies in the correct orbit for more than 90 days, enabling OneWeb to meet the requirements to secure spectrum bands over which it has priority rights under ITU rules and regulations.These rights will now be confirmed as the UK administration, which has filed our satellite system with the ITU, will complete the required Notification and Registration process of the company’s LEO network.
Thus, if anyone has the “first night right” or priority for the Ku-band on non-GSO, then it is OneWEB.
However, in the USA, as far as I am aware, the FCC has already refused to recognize the priority of OneWEB and sent it and TeleSat LEO to negotiate between themselves and with SpaceX on how they will share this radio frequency spectrum with each other so as not to interfere with each other ... And this it was when Jeff Bezos was just writing his application for Kuiper ... So now that the FSS approved Kuiper's application, they will have to divide it by four ...
