The GeoExplorer 6000 series handheld includes
an integrated GNSS receiver that enables you to
collect GPS and GLONASS data for incorporating
into a GIS or for managing assets.
GPS (Global Positioning System) and GLONASS
(GLObal NAvigation Satellite System) are Global
Navigation Satellite Systems (GNSS). Each
system consists of a constellation of satellites
that orbit the earth. GNSS provides worldwide,
all-weather, 24-hour time and position
information.
Note – To receive signals from GPS or GLONASS
satellites, the handheld must have a clear view of
the sky. GPS or GLONASS positions may not always
be available, particularly in or near buildings, in
vehicles, or under tree canopy.
With the addition of the Trimble Floodlight
satellite shadow reduction technology option,
the GeoExplorer 6000 series handheld’s
integrated GNSS receiver can improve accuracy
and productivity in difficult environments.
Note – To track GLONASS satellites, you must have
the Trimble Floodlight technology option installed
and activated.
