SATELSTATUS reports READY, but RTK corrections are not received

Since RTK corrections require both the base station and rover to be operating correctly, both receivers should be examined for possible failures.

1. Check that the base station receiver has a valid fixed position.

   LOG BESTPOS

   <OK

    

   <BESTPOS COM1 0 85.5 FINESTEERING 2009 322351.000 02100000 b1f6 32768

   <     SOL_COMPUTED FIXEDPOS 51.11638764437 -114.03831309695 1047.7300 0.0000 WGS84 0.0000 0.0000 0.0000 "131" 5.000 0.000 21 10 10 10 00 86 00 03

   This example assumes a NovAtel receiver is configured as a base station and paired with a with a Satel Radio connected to COM2 and that the Rover has a 900 MHz Satel radio.

2. Check that the base station receiver is outputting corrections to the radio port.

3. Check that the INTERFACEMODE of the base station receiver port is set correctly.

   LOG INTERFACEMODE

   <OK

4. Check that the base station receiver port settings are set correctly.

5. Use the PORTSTATS log to ensure that the transmitted data is incrementing on the base station receiver radio port.

   log PORTSTATS

   <OK

6. Ensure rover receivers have compatible radio settings.

   1. On Rover:

      LOG SATEL9INFO

      <OK

       

      <SATEL9INFO COM1 0 7.5 FINESTEERING 2009 322148.386 02440000 9dd6 32768

7. Ensure Rover Radio port has the correct settings.

   LOG INTERFACEMODE

8. Check that the rover is receiving corrections.

   1. Use the PORTSTATS log to check if received data on the rover radio port is incrementing

      LOG PORTSTATS

      <OK

       

      <PORTSTATS COM1 0 80.5 FINESTEERING 2009 322642.000 02000000 a872 32768

      LOG PORTSTATS

      <OK

       

      <PORTSTATS COM1 0 82.0 FINESTEERING 2009 322713.000 02000000 a872 32768

      // Other ports

      <          COM3 159945 8734 159945 0 49842 0 0 0 0

   2. Use the BESTPOS log to see if the rover has achieved a NARROW_INT solution.

      LOG BESTPOS

      <OK

       

      <BESTPOS COM1 0 79.0 FINESTEERING 2009 322880.000 02000000 b1f6 32768

      <     SOL_COMPUTED NARROW_INT 51.11638765980 -114.03831308755 1064.6285 -16.9000 WGS84 0.0075 0.0071 0.0129 "0" 1.000 0.000 18 18 18 18 00 21 00 33

9. If all settings are confirmed to be correct but the received data is not incrementing, try the procedures in Power Cycle the Radio Module or Factory Reset the Radio Module.

   After a factory reset, the radio must be reconfigured.
