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.
• If you upload and share the images which are
recorded when the setting “GPS” is ”On,” the
record location may be exposed on the Internet
even if you do not intend to do so. If you do not
want to record location information, select
“Off” for “GPS” (page 136).
On triangulating errors
• If you move to another location right after
setting “GPS” to “On” in the menu, it may take
a longer time for the camcorder to start
triangulating, 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
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 camcorder acquires location information
periodically during triangulating.
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.
