Abstract
The present invention relates to a digital sight for a hand-carried projectile-firing device and a method of controlling the digital sight. A digital sight for a hand-carried projectile-firing device according to an embodiment of the present invention is a digital sight for a hand-carried projectile-firing device, the digital sight including an inertial sensor package and a manual rotation device, wherein the inertial sensor package includes a gyroscope and an accelerometer module. In accordance with the present invention, equipment for measuring the firing direction of a hand-carried projectile-firing device such as a mortar is replaced with a digital sight for a hand-carried projectile-firing device, which reduces an estimation error while using a single medium-low level gyroscope, thus enabling the projectile-firing device to precisely and promptly fire a projectile and improving the operability thereof.

5. A method of controlling a digital sight for a hand-carried projectile-firing device, comprising:
-
a step (S100) of, by using a vertical accelerometer and a horizontal accelerometer, performing horizontal alignment and then aligning a gyroscope measurement axis with a firing direction; a step (S200) of, after the aligning step (S100), acquiring a first approximate azimuth angle from auxiliary information; a step (S300) of, after the step (S200) of acquiring the first approximate azimuth angle, calculating a second approximate azimuth angle; and a step (S400) of, after the step (S300) of calculating the second approximate azimuth angle, calculating a first precise azimuth angle, wherein the step (S300) of calculating the second approximate azimuth angle comprises a step (S310) of determining availability of the first approximate azimuth angle acquired at the step (S200) of acquiring the first approximate azimuth angle. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)
