How to reach "FIXED" RTK state - HD408 Auto Steer

Achieving "Fixed" RTK state is required prior to calibration and auto steer use.

Ensure GNSS is properly updated:

1. On the main screen, click the gray “Radio Station” tab in the top left corner
   1. Click the “Auto Search” tab at the top of the screen
   2. Select one of the options labeled ‘PPP’, we recommend “SBAS" 
   3. Check the box next to “Reset GNSS,” then press “OK.”
   4. After selection, RTK state will say "Single Point" or “Psuedorange.” Continue to step 2.
       
2. Drive machine to an open area without nearby buildings or trees (100yd radius). Wait 10-15 Minutes for PPP (Precise Point Positioning) GNSS to connect. 
   1. RTK state will start as "Single Point," change to "Pseudorange," and then become "Fixed." (Top Left in black bar)
   2. Number of satellites will reset to "0" and then begin to climb. 
   3. Do not move the tractor or touch the screen during this process (10-15 minutes). 
   4. “Fixed” state is required to proceed with calibration and auto steering. 
   5. Confirm the Number of Satellites is adequate and the map on the home screen represents your location (Internet required for initial map). Click the blue globe icon in the upper right-hand corner to refresh the map.
   6. The tractor icon should appear on screen once the machine starts moving. 
      
      

Once calibrated, a “Fixed” state should be achieved easily at the start of each use. It should take less than 10 minutes for the system to reconnect and reach this state. It is best to re-establish the connection in an open area that is free of trees, buildings, or obstacles within a 100-yard radius. You may also have to reconnect after traveling to a new field.
