METHOD FOR DETERMINING A SHIP'S HEADING EMPLOYING AN ELECTRO-OPTICAL ANGLE MEASURING DEVICE

Surveying means and method are shown for measuring the angles of a triangle one corner of which is on an unstable platform. An optical system establishes a base line, which will move parallel to itself in response to movement of the platform without altering any of the angles of the triangle.
