GPS (DSC-TX200V 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] (DSC-TX200V only).
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.
