Location Data
•
The camera may in certain cases need additional time to acquire
location data, for example immediately after the battery is inserted,
when the location data function is enabled for the first time, or after an
extended period of disuse.
•
The positions of navigation satellites change constantly. This may slow
or prevent the acquisition of location data in some locations or at
certain hours of the day.
•
Satellite signals may be blocked or reflected in the locations listed
below, rendering the data acquired less accurate or preventing its
acquisition altogether.
- In buildings or under ground
- Between tall buildings
- Under bridges
- In tunnels
- Near power lines or similar structures
- In dense forest
- In metal briefcases or other containers
•
The presence of cellular telephones or other devices that transmit on
frequencies close to those of navigation satellites may interfere with the
acquisition of location data.
