The expert emphasized the unusual approach of the Russians to protect the satellite navigation antenna (GNSS) from radio-electronic warfare (HRB)-it is located inside the design of four concentrics. In his opinion, the occupiers wanted to protect GPS from satellite signals reflected from Earth, when special accuracy was needed. The Danielr OSINT analyst suggested that the combined antenna with a grounding and a throttle ring.
According to him, throttle rings are designed to reduce undesirable effects from multi -ray interference caused by reflection and diffraction of signals. They can be printed from ordinary plastic on a 3D printer and then covered with a conductive material, such as a copper tape. In turn, a designer with Nick Norestbecausewiked wrote in comments that similar antennas use surveyors to reduce the effect of signal reflection.
We will remind, "Baba Yaga" is a name that Russians apply to Ukrainian heavy drone-bombers who can destroy heavy equipment and live power of the invaders, in particular at night. These include models such as "Bat 620", "Vampire", R18, as well as a modernized industrial drone DJI Matrice 300. Unlike other UAVs, Baba Yaga type drones are completely unacceptable to the means of HR.
