Self-leveling laser horizon for navigation guidance

Abstract

The present invention includes an artificial horizon device including a sensor unit with a movable platform, at least one actuator linked to the platform, and one or more sensors located on the platform for sensing the position orientation of the platform relative to an external mass or the motion of the platform. The horizon device also includes a processing unit signally connected to the sensors and the at least one actuator. The processing unit is adapted to receive signals from the sensors and send signals to the actuators to move the platform to a horizontal orientation. The horizon device also includes either a display unit comprising an indicator of a horizon line which substantially corresponds to the horizontal orientation of the platform or a secondary device.
