This command can be used to enable or disable the automatic determination of the reference
(held) position for timing.
Synopsis
:
$PSTMPPS,2,14,<Samples><cr><lf>
where
Samples
is the number of position samples to be used by the auto-position survey
algorithm. If
Samples
is set to 0, the algorithm is disabled. Otherwise, if a non-zero value
is provided and the SL869-T is not in Position Hold mode, the algorithm is restarted using the
specified number of position samples. It is recommended that the number of samples should
be chosen to allow the algorithm to run for one hour or longer. For best results 24 hours is
recommended.
Example
:
Start and run the auto-position algorithm for 2 hours (at 1Hz fix rate):
$PSTMPPS,2,14,7200
It is important to note that the reference position for Position Hold will be updated when the
algorithm completes its position estimation. If a reference position was entered manually via
command, it will be overridden.
NOTE:
Factory default is that the automatic survey algorithm for position hold is enabled with
a sample count of 3600 (one hour). If it is desired for the module to use a reference
position provided by the user, the sample count should be set to 0 at start-up.
This command can be used to disable or enable the T-RAIM algorithm.
