Modernization of MLRS BM-21 "Tornado-G"
To increase the firing accuracy and efficiency, the deployment speed and to improve the interaction with adjacent units BM-21 “Tornado-G“ multiple launch rocket systems are equipped with the “Alliance” automated control system, as well as an on-board navigation system that integrates weapons into the satellite system GLONASS.
As a result of such modernization, Tornado-G’s firing accuracy increases significantly and it becomes possible to act as part of a unit under the leadership of a single control center.
The preparation time for a multiple rocket launch is reduced to 30 seconds, and
the deployment on the ground takes only 60 seconds
On-board navigation system
On-board navigation system (hereinafter - NS) based on a strap down inertial navigation system corrected according to data received from the receiver of signals of global navigation satellite systems (GNSS) and an odometer.
Automated workstation ARM-K integrated into the Alliance system that provides:
– meteorological, ballistic, topographic and geodetic support;
– artillery fire control;
– remote entry of missile flight mission data;
– receiving and transmission of information about the target;
– collecting, processing, storage and sharing of data;
– receiving of the MLRS current coordinates from the NS;
– target type date input by the commander, automatic display of the detected target on the electronic map in the form of a symbol linked to the displayed electronic map scale
– determination of the current coordinates of the MLRS in real time;
– determination of the current angular orientation of the MLRS - course, roll, pitch;
– determination of the MLRS motion parameters - distance traveled, speed;
– field topographic location and orientation of the MLRS;
– the MLRS range indication and calculation;
–launch tubes homing from the cabin using the gunner's console.
