About GPS (DEV-5/5K)
The GPS (Global Positioning System) is a
system that calculates geographical location
from highly accurate US space satellites.
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
(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 this product.
“GPS” is a system for determining geographic
location by triangulating radio signals from
GPS satellites. Avoid using this product in
places where radio signals are blocked or
reflected, such as a shadowy place surrounded
by buildings or trees, etc. Use this product 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 this product 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 this product: near 1.5
GHz band mobile telephones, etc.
On triangulating errors
If you move to another location right after
turning the power switch to ON, it may
take a longer time for this product to start
triangulating, compared to when you stay in the
same place.
Error caused by the position of GPS satellites
This product automatically triangulates your
current location when this product 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
This product acquires location information
periodically 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
Use GPS in accordance with the regulations of
the situation, the countries/regions of use.
On the geographic coordinate system
The “WGS-84” geographic coordinate system
is used.
