Abstract
The portable precision watch, additionally to time-keeping functions, also comprises a GPS receiver with antenna, evaluation electronics, a compass, a destination coordinate memory, an input element and a display element. With the evaluation electronics the coordinates of the location and the direction to the destination are computed and are made directly viewable as a vector display in the display element. Thus a very compact precision watch is provided which may be personally carried everywhere and worldwide, and directly displays the direction to any destination, in particular as a pocket watch or wrist watch.
Claims22
A portable precision watch with time-keeping functions, additional functions and energy storage means, wherein the watch also contains
- a GPS receiver with an antenna and evaluation electronics,
- a compass for determining the magnetic north-south direction,
- a memory for storing destination coordinates,
- an input element for inputting selectable destination coordinates,
- and a display element for displaying the direction from a location to a destination, wherein
- with the evaluation electronics, the coordinates of the location are determined and
- from the coordinates of the location and the coordinates of the destination, the direction to the destination is calculated,
- wherein by way of the compass the alignment of the watch to the geographical north-south direction is determined and taking account of this alignment of the watch, the direction to the destination is made viewable as a vector display in the display element,
- wherein all elements are grouped together as a compact functional unit and the computation of the data is effected in a microprocessor
- and wherein the watch time can be controlled by the received GPS time.
