The GeoExplorer 2008 series handheld includes
an integrated GPS receiver that enables you to
collect GPS data for incorporating into a GIS or
for managing assets.
The Global Positioning System (GPS) is a
satellite-based positioning system consisting of a
constellation of operational NAVSTAR satellites
that orbit the earth every 12 hours. This system
provides worldwide, all-weather, 24-hour time
and position information.
Note – To receive signals from GPS satellites, the
handheld must have a clear view of the sky. GPS
positions may not always be available, particularly
in or near buildings, in vehicles, or under tree
canopy.
