Acquiring GPS Signals
Places with Poor GPS Coverage
Location information may not be recorded, or inaccurate information may be
recorded where GPS signal coverage is poor, such as in the following
places.
Indoors, underground, near buildings or in valleys, in tunnels or forests
Near high-voltage power lines or mobile phones operating on the
1.5 GHz band
When the receiver is inside a bag or suitcase
When traveling through different environments
Even in other places, GPS satellite movement may interfere with
geotagging and cause missing or inaccurate location information. The
information may also indicate that the camera has been used in a
different location, even if you are shooting at the same place.
