This system allows you to pinpoint your exact location on the earth. The GPS satellites are
located in 6 orbits, 20,000 km above the earth. 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 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 camera.
“GPS” is a system for determining geographic location by triangulating radio signals from GPS
satellites. Avoid using the camera in places where radio signals are blocked or reflected, such
as a shadowy place surrounded by buildings or trees, etc. Use the camera 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 camera 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 camera: near
1.5 GHz band mobile telephones, etc.

On triangulating errors

If you move to another location right after turning on the camera, it may take a longer time for
the camera to start triangulating, compared to when you stay in the same place.
Error caused by the position of GPS satellites
The camera automatically triangulates your current location when the camera receives radio
signals from 3 or more GPS satellites. The triangulating error allowed by the GPS satellites is
about 10 m (33 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 United
States Department of Defense, and the degree of accuracy may be changed intentionally.
Error during the triangulating process
The camera acquires location information periodically. 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, turn off the camera, as you will be instructed to do
by the onboard announcement.
If you do not want to record location and direction information, select [Off] for the GPS setting.

On the other restriction

Use GPS in accordance with the regulations of the place or situation.

On the geographic coordinate system

The “WGS-84” geographic coordinate system is used.
