This command implements position averaging for reference stations. Position averaging will continue for a
specified number of hours or until the averaged position is within specified accuracy limits. Averaging will stop
when the time limit or the horizontal standard deviation limit or the vertical standard deviation limit is achieved.
When averaging is complete, the 

FIX

 

POSITION

 command will automatically be invoked.

If the maximum time is set to 1 hour or larger, positions will be averaged every 10 minutes and the standard
deviations reported in the 

PAVA

/

B

 log should be correct. If the maximum time is set to less than 1 hour, positions

will be averaged once per minute and the standard deviations reported in the log will likely not be accurate; also,
the optional horizontal and vertical standard deviation limits cannot be used.

One could initiate differential logging, then issue the 

POSAVE

 command followed by the 

SAVECONFIG

 command.

This will cause the GPSCard to average positions after every power-on or reset, then invoke the 

FIX

 

POSITION

command to enable it to send differential corrections.
