The Defence Intelligence of Ukraine (DIU) is publishing details on the War&Sanctions portal about a new version of russian Geran-4 jet-powered UAVs, which the enemy began using this autumn.
The upgraded Geran-4 features a new “MOKh” module based on a high-precision magnetic induction sensor (magnetometer), the PNI5GA manufactured by the U.S. company PNI Sensor. The “MOKh” works in conjunction with the SADRA inertial navigation module, reducing gyroscope drift and improving the UAV’s autonomous navigation accuracy.
In addition to satellite and inertial navigation, the enemy has introduced another autonomous navigation system, “Susanin”. This is an electro-optical correlation system that compares images from an optical sensor with a reference image stored in the computer’s memory to ensure that the UAV follows the designated route from the launch point to the target point. A similar system is also used on the new K5 version of Geran-5 UAVs.
To effectively strike bridge structures and overhead power line supports by cutting them with a shaped-charge jet, the enemy has begun using a new KRSN warhead (shaped-charge cutting special payload).
The Chinese Telefly turbojet engine has been replaced by a russian-made equivalent, localized in alabuha.
The remaining electronic units and components are unchanged and identical to those used in previous Geran UAVs.
DIU continues its systematic work to study and expose new developments by the aggressor state.
