Accuracy of position and height?

  • Hi there Becker users,

    (Antworter in Deutsch sind auch OK...)

    If you enter the "installation menu" of the Becker (press NAV (twice) followed by keys 3 and 5) you are able to see all sattelite info like coordinates on earth, number of satelites, heigth (also when there are less than 5 satelites ;) etc...

    But what I would like to know for sure what's the number shown to the left bottom side of the display. In V5 it was marked "G" I think, and in V6 it is marked "D" or so (I'm not sure, but you must know what I'm talking about...)

    I do know this number decreases when you receive more satelites, so I guess it's some sort of accuracy indication (Genauigkeit???). But I want to know for sure, and I want to know the precise unit.... ;-)))

    For instance I see numbers like 2.0 and 1.8. The best I ever got was 1.6 if I remember correctly. Does this indicate a 1.6 meter accuracy of your location calculation???

    And if it indeed is the accuracy in meters; how to calculate with it? An calculation-example for instance: If the heigth is marked "100 m" and this mystery number shows "2.0", within what range is my real height? Is it between 100 +/- 2.0 m, so somewhere in between 98 and 102 meters, or does it indicate a sphere of in-accuracy so my real heigth should be in between 96 and 104 meters....

    I'm curious who can solve this.....

    Best regards, Mit Freundliche Grusse, Johan.
