GPS (DSC-HX20V/HX30V only)
On GPS
●
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, set [Airplane Mode] to [On].
●
If you do not want to record location and direction information, set [GPS setting] to [Off].
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.
