POSITIONING
When using the mobile phone positioning along
with some separate map, e.g. a paper map, the GPS
position format and map datum need to match the
position format and map datum listed on the cor-
responding paper map.
The settings below are correction factors, which
will be applied to GPS position fixes before they
are displayed.
Position format
Position format indicates the way the position will
be displayed. The position can be displayed either
by the most common latitude/longitude system or
some other coordinate measuring system.
1. Select
Position format and press - CHANGE.
2. Select an option with
n. Press - OK.
You can choose in which format you want to see
the coordinates:
•In degrees, minutes and seconds
(
hddd°mm’ss.s’’).
•In degrees and minutes (
hddd°mm.mmm’).
•In degrees only (
hddd.ddddd°).
•In one of the pre-defined grid formats.
•In
User UTM grid. In case you need to use a grid
which is not available in the list, you can create a
user UTM grid to match your paper map. Select a
line by pressing
n and - CHANGE. Fill in the dig-
its and press
- OK. Complete the grid by press-
ing
. DONE.
On the Position page and in other similar places se-
lected position format is shown abbreviated.
Map datum
Map datum, such as WGS84, determines a starting
reference point for selected position format as well
as the shape of an ellipsoid.
1. Select
Map datum and press - CHANGE.
2. Select an option with
n. Press - OK.
•You can select one of the pre-defined map
datums shown in the list.
•You can create your own datum, i.e.
User datum,
as well. When creating the user datum, the first
two lines indicate the starting point of the coor-
dinates while the rest two lines indicate the
shape of the ellipsoid, which is used to represent
the shape of the Earth.
