Inertial navigation sensors essential for drones continue to enter Russia from China — including those made by Western companies
Russia continues to import inertial navigation sensors, gyroscopes, and accelerometers — key components for drone navigation alongside satellite guidance, The Insider has discovered after analyzing Russian customs databases.
Inertial navigation relies on accelerometers to measure acceleration and gyroscopes to track a device's movement, enabling the calculation of trajectory through motion equations. Magnetometers further enhance accuracy by detecting the Earth's magnetic field direction. High-quality inertial sensors are essential for drones in combat situations — especially when adversaries disrupt satellite signals.
In 2024, the leading importer of inertial sensors to Russia was LLC “FabTsentr” — a company linked to the Ostek («Остек») and Yadro FAB Dubna («Yadro ФАБ Дубна») groups, both of which feature prominently in The Insider’s previous reporting. Ostek has been involved in supplying electronics and industrial equipment for manufacturers of “Kinzhal” missiles, while Yadro has relied on foreign-made components in the production of its internet filtering technology.
In second place is LLC «Lumos» (ООО «Люмос»), which — as previously revealed by The Insider — is responsible for a significant portion of drone component imports into Russia.
In third place is LLC «Mach Unit» (ООО «Маш Юнит») — a major electronics manufacturer and retailer with significant revenue, multiple certifications, and a well-developed website.
