GPS is a function to retrieve location information of
the FOMA terminal by receiving radio wave from
GPS satellites. Enable location information services
([Use wireless networks] or [Use GPS satellites]) to
measure the present location (
n
P. 80).
You cannot use the FOMA terminal as navigation
system for professional use of aircrafts, vehicles,
person, etc. or surveying GPS of high accuracy.
Note that DOCOMO shall not be liable for the
pure economic loss caused by using for these
purposes or other purposes such as you cannot
confirm the positioning (communication) result
with the FOMA terminal failure, malfunction or
external factors such as power failure (including
battery exhaustion).
GPS is the service administered by Department
of Defense of USA. Therefore, GPS radio wave
condition may be controlled (accuracy
degradation, radio wave abort, etc.) for the US
national security reason. In addition, the same
results may not be retrieved even when
positioned in the same location and environment,
since the radio wave condition differs depending
on the location of satellites.
Note that GPS is using the radio wave from
satellites, and following conditions may cause
the radio wave abort or difficulty to receive
resulting in 300 m or more of the error of
retrieved location information.
In or under densely trees, in density area with
buildings or residence
In or under buildings
In basement, tunnel, ground or water
Near high-tension line
Inside cars or trains
In bad weather with heavy rain/snow
In bags or boxes
When people or objects are blocking the
FOMA terminal
When hands are covering camera, earpiece or
proximity sensor of the FOMA terminal
When using a map and GPS function overseas,
the displayed map based on the acquired
location information (latitude and longitude
information) may not be accurate because of the
legal system in each country and the area.
Packet communication charges may be incurred,
since assist data such as satellite information is
automatically retrieved when you position
present location.
Packet communication charges are incurred
when you display a map based on the location
information.
