PURPOSE: A method for correcting a trajectory of a shell is provided to save kinetic energy due to maintaining an arc shape of flight path by generating a small inducement command even when there is a hitting error. CONSTITUTION: A method for correcting a trajectory of a shell includes the following steps: measuring flight data of a launched shell (S110); calculating a path correction angle which is defined as an interval angle between a present speed produced as measured flight data and a speed of the shell heading for a target (S200); calculating an induced acceleration command in order to control a canard wing with the calculated correction angle (S300); and operating the canard wing by delivering the calculated induced acceleration command to a control unit (S400). [Reference numerals] (AA) Start; (BB) End; (S110) Measure flight data; (S120) Is it a target of a launched shell?; (S200) Calculate a path correction angle; (S300) Calculate an induced acceleration command; (S400) Control a canard |
