TCS
Trajectory Correction System
 



 

IMI has developed and successfully implemented a Trajectory Correction System (TCS) that improves the accuracy of free flight artillery rockets to exceed that of tube artillery without adding on-board guidance components. This development provides accuracy capabilities, independent of range, that were previously attainable only with guided missiles – and it provides the capabilities at a low cost.

To correct the rocket's trajectory during flight, RSD has applied a relatively inexpensive, innovative trajectory correction system that is capable of day and night operation independent of weather conditions, and the system can be installed in a wide variety of free flight rockets. This installation transforms simple rockets into accurate, smart weapons that can destroy targets at ranges of 40 km or more at low cost.

The guidance and navigation system in the TCS rockets was developed by IMI's Rocket Systems Division (the Rocket Propulsion facility of IMI considered to be Israel's national center of expertise in this field), in cooperation with Elisra that specializes in electronic warfare and communication.

Major operational advantages over free flight rockets include effective firing against quality targets at long ranges, deployment of smart munitions, optimum damage/ammunition ratio, capability to perform multiple fire missions and capability to engage multiple targets within the same salvo. TCS is suitable for implementation on IMI's entire artillery rocket family, can be adapted to other artillery rocket systems such as LAR-160,GRADLAR, MLRS and PINAKA, or implemented as an upgrade on existing artillery rockets.

 
 
 
 

 
Accular/TCS - Rocket Ammunition
 
The Trajectory Correction System, known as TCS, is available in the 160mm ACCULAR and in other current production of IMI rocket systems and also as an upgrade to existing systems. 
It is currently being supplied as part of the MLRS systems being delivered to the IDF. 

A typical TCS system includes a rocket with an electronic package and thrust vector control (for teering the rocket during flight), and a ground control unit. In a TCS mode of operation, the rocket is launched in a free flight mode and the ground system automatically directs the steering-kit of the rocket to continuously correct the trajectory of the rocket to the required path-to-target.
