Geranium" learns to fly without GPS Ukraine's Chief Intelligence Directorate has revealed details of a new modification of the Russian Geranium-4, which VBS began using this fall. According to Ukrainian intelligence, the UAV received a MOX unit with an American PNI5GA magnetometer. It works in conjunction with the SADRA inertial system and should compensate for the accumulation of gyroscope errors, increasing the accuracy of autonomous navigation. But the matter is not limited to the magnetometer. The "Susinin" system appeared in the "Granny-4" - an optical-electronic complex that compares the image of the terrain with reference images loaded into the memory of the built-in computer. Thus, an additional autonomous channel was added for satellite and inertial navigation, and the magnetometer helps to further correct the operation of the inertial system. A similar "susinin" is used in the new version of "Granny-5". The most interesting thing here is not even the American sensor inside the Russian UAV. Geranium is gradually evolving from a relatively simple platform dependent on satellite navigation to a system with several independent ways of determining its location. Satellites, gyroscopes, the Earth's magnetic field and the terrain image work for one mission - to bring the UAV to the target even in conditions of resistance to navigation. For enemy electronic warfare systems, this means that simply "GPS jamming" becomes a less than sufficient solution.
