[117] Information
On GPS (FDR-X3000/HDR-AS300)
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 that determines your position by receiving signals from satellites. Avoid using the
GPS feature on 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.
If you shoot images while the GPS log is set to ON and upload those images to the Internet, the
shooting location may be visible to third parties. To prevent this, set the GPS log to OFF before
shooting.
[118] Information
On GPS errors (FDR-X3000/HDR-AS300)
If you move to another location right after turning the camera on, 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 during triangulating. There is a slight time
lag 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 the exact location
on the map based on the GPS information.
