Via the second sensors of the control unit, the second markings provide information about the distance by which the globe has been rotated from the reference point.
  • the control unit determines the associated coordinate points. By rotating the globe, the control unit receives information about the position of the position indicator via the first sensor. The control unit now calculates the required direction of rotation and the associated angle of rotation from the target and actual coordinates and either shows this on a display or initiates a corresponding control of stepper motors for rotary actuation of the globe. The adjustment of the globe is monitored using the second markings, by means of which the control unit contains information about the angle through which the globe has been rotated.

In this way, the control unit 22 obtains the target coordinates of the location to be searched. Now it is the globe ball 12 is not moved either manually or by the motor 36. After a brief rotation of the globe, two first markings of the first marking ring 24 have passed the first sensor 28. Since the distance between two markings on the first marking ring 24 is specific to a very specific sector of the globe 12, the control unit 22 recognizes in connection with the second and third sensors 30 and 32, which act as a rotation angle and direction of rotation sensor at which point the location indicator is currently in relation to the globe 12.

In this case, the latitude indicated on the display 18 must be searched on the plexiglass scale 14. In the case of an automatic motorized adjustment of the globe ball, this is set in rotation by the motor 36. The actual coordinates are found in the same way as in the manual operation described above.
  • the control unit uses the stored target coordinates to derive the necessary control pulses for the stepper motors 34 and 36 from the actual coordinates.

  • the different distances between the first markings on the first marking ring 24 are shown in a greatly exaggerated manner for clarification. In reality, their distances are relatively small and do not differ so much from one another as is shown in the schematic FIG. 2. This makes it possible to recognize the reference point after a relatively short rotation of the globe 12.
  • the first, second and third sensors 28, 30 and 32 are designed as light barriers. However, electrical or electromagnetic sensors can also be used. To detect the direction of rotation, a mechanical sensor can also be used instead of the third sensor 32, which indicates the direction of rotation, for example, by frictional engagement with the globe ball.
  • the second marks on the second marker ring 26 are equidistant and in k istsring se 'hr narrow intervals on the Mar ⁇ 26 is arranged. The shorter the distances between the second markings, the greater the accuracy with which the longitude of the position indicator can be set.
