Abstract
The invention refers to a navigation device for the execution of necessary navigation course determinations. Using the device, one can quickly correct the faults attributable to the determination of a course through the use of a magnetic compass. Such faults are declension, deviation as well as possibly even drift. According to the invention the navigation device includes a frame plate (1), and a deviation disc (2) which may be turned and stored on the frame plate (1) at a bearing pivot. The deviation disc (2) is equipped with a compass scale (4) which with the help of the deviation disc turning in relation to the frame plate (1) can determine the degree, and with a bearing point (A) surround the closed deviation curve (6). The frame plate (1) or a plate connected to this is on a corresponding manner, equipped with a reading line (7) for deviation. Further belonging to the navigation device and at a distance from the bearing point (A) there is a declination scale (5), which can be indicated by using this as well as the necessary pivot point (D)of the navigation device. The compass course can be read on the deviation plate's (2) compass scale (4) the reading point location (E) is obtained by one through the storage point (A) proceeding normally (8) to one through the deviation point (C) and the pivot point (D) walking line (21). In practice this line is attained (21) and is the norm (8) i.e. through the use of the coordinate system which the longitude and latitude on a map form.<IMAGE>
