Artillery Rockets Benefit From Incorporated GPS System

On behalf of the German Federal Office For Defence Technology and Procurement (BWB), Rheinmetall Defence live fire tested their Corect guidance module with great success. Two test rockets were guided to a target 20 km away using the company’s new, satellite-supported flight path guidance modules. The modules compensated for an approximate 300 m lateral error and proved the effectiveness of the Corect guidance module with the Multiple Launch Rocket System (MLRS). A budget proposal will now be prepared for final development, pre-production work and manufacture.




The increase in accuracy is due to an integrated GPS receiver. The actual position of the rocket is determined, with the rocket measuring the earth’s magnetic field through a magnetic field sensor mounted in the projectile. On on board processor calculates the banking of the rocket and, based on this data, any deviation from the intended flight path is calculated. To correct lateral and elevation direction, precisely timed impulses of the radially operating microjets are initiated—Düsseldorf, Germany
