About GPS

The GPS system consists of 24 or more GPS
satellites. A GPS receiver receives radio signals
from the satellites, and calculates the current
location of the receiver based on the orbital
information (almanac data) and travel time of the
signals, etc.
Determining a location is called "triangulating. " A
GPS receiver can determine the location's latitude
and longitude by receiving signals from 3 or more
satellites.
As the positions of GPS satellites vary

constantly, it may take longer to determine
the location or the receiver may not be able to
determine the location at all, depending on the
location and time you use the camcorder.
"GPS" is a system for determining geographic

location by triangulating radio signals from
GPS satellites. Avoid using the camcorder
in places where radio signals are blocked or
reflected, such as a shadowy place surrounded
by buildings or trees, etc. Use the camcorder in
open sky environments.
You may not be able to record location

information at locations or in situations where
radio signals from the GPS satellites do not
reach the camcorder as follows.
In tunnels, indoors or under the shade of

buildings.
Between tall buildings or at narrow streets

surrounded by buildings.
In underground locations, locations

surrounded by dense trees, under an elevated
bridge, or in locations where magnetic fields
are generated, such as near high voltage
cables.
Near devices that generate radio signals of the

same frequency band as the camcorder: near
1.5 GHz band mobile telephones, etc.
On triangulating errors
If you move to another location right after

setting the GPS switch to ON, it may take
a longer time for the camcorder to start
trianguating, compared to when you stay in the
same place.
Error caused by the position of GPS satellites

The camcorder automatically triangulates your
current location when the camcorder receives
GB
10
radio signals from 3 or more GPS satellites. The
triangulating error allowed by the GPS satellites
is about 30 m (98 feet). Depending on the
environment of the location, the triangulating
error can be greater. In this case, your actual
location may not match the location on the map
based on the GPS information. Meanwhile,
the GPS satellites are controlled by the Unites
States Department of Defense, and the degree of
accuracy may be changed intentionally.
Error during the triangulating process

The camcorder acquires location information
every 10 seconds during triangulating. There
is a slight time difference between when the
location information is acquired and when the
location information is recorded on an image,
therefore, the actual recording location may not
match exactly the location on the map based on
the GPS information.
On the restriction of use of GPS on an airplane
During take off and landing of an airplane,

set the GPS switch to OFF and turn off the
camcorder, as you will be instructed to do by
the on-board announcement. In other cases, use
GPS in accordance with the regulations of the
place or situation.
On the map data
The camcorder contains map data for the

following countries/regions.
Europe, Japan, North America, Oceania, etc.
Built-in map is powered by companies as

follows; Map of Japan by Zenrin Co., Ltd., other
areas by NAVTEQ.
The map data included is as of the date of

production of this manual.
GPS maps will appear in 2-dimensional

graphics except for certain landmarks in Japan,
which will appear in 3D.
The map always displays the north at the top.

You cannot change the language on the map.

You cannot update the map data.

The scale of the map is 25 m to 6,000 km (or

100 feet to 6,000 miles).
