Improvement of the accuracy of artillery fire can also be achieved by the use of course correction techniques, implementing new braking mechanisms. Such an application is SPACIDO fuse developed under a DGA program by GIAT, TDA Armament and IN-SNEC as an upgrade for in-service artillery shells. The system is built into the fuse and is composed of three discs air-brake and associated electronics. SPACIDO designed to improve by x4 the hit accuracy, by adjusting the actual ballistic trajectory of the specific shell to match the theoretical trajectory which is used to compute the firing parameters.
