  • Patent number: 10222214
    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.

  • Publication number: 20160377382
    Abstract: Disclosed herein is a digital sight for a manually-portable shell-firing mortar. The digital sight includes a first accelerometer, a second accelerometer arranged perpendicular to the first accelerometer, a gyroscope arranged perpendicular to the first and second accelerometer, and a controller configured to calculate and display a re-firing direction varied from a primary-firing direction, using the first and second accelerometers and the gyroscope.
