METHOD FOR PROVIDING NAVIGATION AND / OR GUIDANCE AND / OR CONTROL OF A PROJECTILE TO A GOAL AND DEVICE IMPLEMENTING SUCH A METHOD

摘要

The subject of the invention is a method for ensuring navigation and / or guidance and / or steering of a projectile (1) towards an objective (B). As a result of this method, at least one value of three components of a reference magnetic field (HMB0) in a fixed terrestrial reference centered on the firing position (13) and whose orientation relative to the direction of the objective (B) is known and fixed or programmed, at least one azimuth angle value is set or programmed, and at least one measurement of the three components of the magnetic field is carried out on a trajectory in relation to the projectile. Finally, the angles of roll and roll are calculated. from the measured and programmed values.The invention also relates to a device implementing such a method
