80 GeoExplorer 2005 Series Getting Started Guide
Problem Cause and Solution
Not receiving
real-time
corrections
from external
source
No physical connection
Connect the external real-time source to COM1 using the optional
serial clip (P/N 53550-00), or to a Bluetooth port on the handheld.
Not connected to real-time COM port correctly
In the Real-time section in the GPS Controller or TerraSync software,
or the GPScorrect or GPS Analyst extension, select the serial (COM) or
Bluetooth (BSP) port that the real-time source is connected to.
If you are using a non-Trimble application, use GPS Connector to
create a connection between the COM or BSP port and the integrated
GPS receiver’s real-time GPS COM port (COM4).
Incorrect port settings
Change the port settings to match those used by the external source.
No GPS positions
You cannot use real-time corrections until the GPS receiver is
computing positions. In the application, make sure that the
integrated GPS receiver is activated, enough satellites are available,
and the satellite geometry (PDOP) is good enough to compute
positions.
No Bluetooth connection to external correction source
The Bluetooth external correction source is more than ten meters
from the handheld, or is obstructed. Move the devices closer
together, in a direct line of sight, to re-connect.
Integrated SBAS selected as second real-time choice
If the SBAS status is Waiting, the integrated GPS receiver may
incorrectly change the status of the preferred real-time choice to
Waiting as well. To avoid this, select Wait for real-time or Use
uncorrected GPS as your second choice.
NMEA data
includes
autonomous
positions
Integrated GPS receiver outputs autonomous positions when
real-time corrections are unavailable.
Configure your NMEA application to filter out non-DGPS positions.
