Using GPS function
„
z GPS is a function to retrieve location information of
devices by receiving radio wave from GPS satellites. It
is necessary to set Location to [ON] to measure the
☞
present location (
z You cannot use the handset as a 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 losses such
as ones caused by using the GPS for these purposes
or by failing to confirm a positioning result or to
communicate due to handset failure, malfunction or
external factors such as power failure (including
battery exhaustion).
z GPS is a service administered by the U.S. Department
of Defense. Therefore, GPS radio wave condition may
be controlled (accuracy degradation, radio wave abort,
etc.) for US national security reasons. In addition, the
same results may not be retrieved even when
positioned in the same location and environment, since
the radio wave conditions may change depending on
the location of the GPS satellites.
P. 133 "Location").
z Note that GPS uses the radio waves from artificial
satellites, therefore the following conditions may
prevent the radio waves from being received or prevent
the reception status of the radio waves from being
satisfactory, resulting in an error of 300 m or more for
location information.
„ In or under a dense forest, in density area with
buildings or residence
„ In or under buildings
„ Inside a basement or tunnel, underground or
underwater
„ Near high-tension line
„ Inside cars, trains, etc.
„ In bad weather with heavy rain/snow etc.
„ Inside bags or boxes
„ When people or objects are blocking the handset
„ When hands are covering the GPS antenna area
z When using a GPS function overseas, the content
based on the acquired location information (latitude
and longitude information) may not be accurate
because of the legal system etc. in each country and
the area.
z Assisted GPS data such as satellites information may
be automatically retrieved when you measure present
location.
