Data Link Okay but No Fixed Position Computed

Step 2. Is the

If you have a license for only one frequency, you may
need to find another frequency in your area that is
clear of traffic in order for the system to function
reliably and acquire a license for this frequency if
possible.
RTK Base
Relevant to
Once the receiver is set to function in RTK (i.e. RTK firmware
option has been enabled), it will compute RTK quality
positions. In order to accomplish this, the rover must collect
raw satellite data at its position and also receive RTK
correction data transmitted by the base. Without these two
components, the rover will not be able to fix RTK position
solutions.
To determine if the rover is computing a fixed position, you
can read the General Status screen (2nd parameter in upper
line), or use FAST Survey (Equip tab, Monitor Skyplot function).
Using either the display screen or FAST Survey, you have
determined that the rover system is not computing a "Fixed"
position. Follow the steps outlined below to troubleshoot this
problem.
To determine if the rover is receiving base data, examine the
2nd line on the General Status screen. The Data Link icon
should be visible. Refer to Radio Data Link Fails to Provide
Base Corrections to Rover on page 357 if you need to fix this
problem, and then come back to this procedure.
Use either the front panel of the receiver or FAST Survey
running on the field terminal to determine if the rover is
tracking satellites.
• If the receiver is not tracking satellites, refer to Receiver
is Not Tracking Satellites on page 354 and then come
back to this procedure.
• If the receiver is tracking satellites, go to step 3 below.
