The handheld is not
receiving GPS positions.
The integrated GPS receiver is
not activated.
Use the Connect or Activate GPS command in your
GPS field software to activate the integrated GPS
receiver. For more information, see
The GPS COM port is already
in use.
Only one application at a time can have the port
open. Exit the software that is using the GPS COM
port and then retry in your application.
The GPS field software is using
the wrong GPS COM port.
Connect to COM7.
Not enough satellites are
visible.
Move to a location where the receiver has a clear view
of the sky and ensure the antenna is not obstructed.
The handheld is not
receiving SBAS real-
time corrections.
The SBAS satellite is
obstructed from view.
Check the location of the SBAS satellite in the Skyplot
section of your GPS field software, and if possible
move to a different location.
You are outside the SBAS
satellite coverage area.
If you have selected satellites that are not available at
your location, you cannot use SBAS corrections.
NMEA data includes
autonomous positions.
The integrated GPS receiver
outputs autonomous positions
when real-time corrections are
unavailable.
Configure your NMEA application to filter out non-
DGPS positions.
