In the examined samples of guided rockets from the Tornado-S multiple rocket launcher system, used by Russia against Ukraine, it was found that two fiber-optic gyroscopes were used simultaneously:
- TIUS500, manufactured by the Russian company NVK Optolink;
- A foreign-made product with no manufacturer markings, featuring Chinese-language indicator seals and visual similarity to the AgileLight gyroscopes produced by the Chinese company BWSENSING.
The use of two gyroscopes at once aims to increase targeting accuracy by providing two sets of information regarding the object's current position in space.
The foreign and Russian devices have a similar structure: they both include three Sanyak ring interferometers, placed along three orthogonal axes, and electronic boards.
The electronics in the Russian unit are based on the Altera Cyclone (USA) programmable logic matrix (FPGA), while the foreign unit uses an STMicroelectronics (Switzerland) microcontroller.
Additionally, the Russian unit contains components from manufacturers in the USA (Analog Devices, National Semiconductor, Maxim Integrated), China (Panwoo Equipment Consulting, Mornsun), Switzerland (STMicroelectronics), and the UK (Golledge Electronics).
A full list of components and their photos has already been published on the War&Sanctions portal, which currently contains over 18,000 objects and subjects across ten sections.
