Jamming the Rassvet satellites will require a fundamentally different approach than the countermeasures against UAVs or communication systems that Ukrainian developers are accustomed to.
A dome-shaped electronic warfare station creates interference around a protected object and affects receivers that fall within its range. In the case of a satellite network, the target is the onboard receiver at an altitude of approximately 500-550 kilometers, and potentially up to 800 kilometers. Therefore, the system must not form a constant dome, but rather direct a narrow beam at a specific satellite and track it as it passes over the horizon.
For Ukrainian manufacturers, this represents a new class of challenges. Most publicly presented Ukrainian anti-drone systems operate at frequencies up to 6 GHz, and in some cases up to 9 GHz. There is no information in open sources about Ukrainian mass-produced systems capable of generating directional radiation at frequencies around 14 or 30 GHz while simultaneously automatically tracking low-Earth-orbit satellites
Russia is working on replacing Starlink, It was a really hard blow to Russia when the access to Starlink was closed to them back in February. And the effect was immediately visible on the front lines!
So yes it will be bad for Ukraine if Russia manages to get their own program working.
Ukraine is now talking about a program to take out Russian satellites, IDK if that is a feasible suggestion, but it is for sure being investigated by Ukraine.
