Troubleshooting 5
Tracking but not receiving a
differential signal
The receiver is tracking satellites and
tracking an OmniSTAR satellite
beam, but is not receiving DGPS
signals. The Home screen indicates
how many satellites are being
tracked, and whether a differential
source is being tracked.
You see:
h-3D for HP not converged
H-3D for HP converged
r-3D for RTK float
R-3D for RTK fixed
D-3D for DGPS
HP and RTK also give an indication
of positional accuracy on the Home
screen (AgRemote).
Check that your DGPS service subscription is still
current and enabled.
For OmniSTAR service:
1. Use the AgRemote utility to navigate to one of the
following screens, depending on what you are
using:
• the Omni HP Info
Omni VBS Info
2. Press 4 until Stop Date
If the message
Access Unknown
appears, contact
OmniSTAR to reactivate your subscription. For more
information, see OmniSTAR, page 29.
The receiver must be switched on and configured to
track the correct satellite coverage beam before it
can be reactivated.
The receiver automatically tracks the correct beam
based on receiver geographic location. If the receiver
is manually changed, automatic tracking is
deactivated until you perform a hard reset or
firmware flash.
When a satellite subscription is activated, the Home
screen displays
D/3D
.
