6.4.6 $JSMOOTH
There is a new command, $JSMOOTH that enables the user to change the carrier smoothing
interval between 15 minutes and 5 minutes. This command was designed to offer the user
flexibility for tuning in different environments. You may find a slight improvement in positioning
performance using either the short or long smoothing interval depending on your multipath
environment. The default for this command is 15 minutes or LONG. To change the smoothing
interval to 5 minutes or SHORT, use the following command.
$JSMOOTH,SHORT<CR><LF>
If you wish to change the smoothing interval to 15 minutes or LONG, use the following command.
$JSMOOTH,LONG<CR><LF>
If you wish to request the status of this message, send the following command. The status of this
command is also output in the $JSHOW message.
