General information regarding the GPS
reception
In order to be able to use the function of your GPS optimally, the below
mentioned instructions must certainly be followed.
The GPS watch is a global positioning system (=GPS), which serves especially
for measuring the distance, speed, height and navigation by means of USA
satellite network. The USA operates this satellite system and also responds
for their exactness and maintenance.
The reception of the signal, without problems, from a satellite can only be
guaranteed
under calm weather conditions
(clear sky) and an adequate
reception area –
open area with clear view to the sky
.
Because satellite signals react very sensitively to external influences, bad
weather (e.g. heavy snowfalls), as well as a perturbed reception area (the
GPS watch is covered by clothes or other objects, high buildings or narrow
valleys and defiles impede the reception) can affect significantly the
efficiency and exactness of the GPS watch.
Inside the buildings, GPS reception is strongly restricted or impossible. Near
the windows, and also in spaces with large windows and clear view to the sky
a determination of the location can be possible, under certain circumstances,
depending on the momentary position of the satellites. In interior spaces and
in basements the GPS reception is practically impossible.
