3.2.10.9 DEVICE.GPS.STARTUP

Parameter syntax
This parameter controls the start-up behaviours of the integrated GPS engine.
<mode>
It determines whether to power on or off the GPS engine during startup. It can
be set to:
Value
on
off
How to set/get device configuration:
$PFAL,Cnf.Set,DEVICE.GPS.STARTUP=on
Set configuration
$PFAL,Cnf.Get,DEVICE.GPS.STARTUP
Get configuration
Notes
Note that, all GPS related PFAL commands will not be executed or might
•
result errors and read commands will not work, if GPS engine is not properly
initialized and running.

3.2.10.10 DEVICE.GPS.AUTOCORRECT

Parameter syntax
This parameter activates an internal GPS position check routine to filter out the
incorrect or improbable GPS positions. Main purpose is to filter out „GPS position
bounces" that may happen in that areas with very poor GPS signal quality.
<type>
It determines whether or not to enable GPS auto corrections. It can be set to:
Value
on
off
<max_pdop>
It specifies the maximal allowed PDOP value (broken value may also be set –
e.g. 4.8 )
<max_speed>
It specifies the maximal speed limit. Any speed exceeding this setting will be
ignored (i.e. no position will be computed from this GPS record)
<dist_error>
It specifies, in meter, the maximal allowed distance error. Former GPS records
are analysed. According to their speed, a distance is computed and compared
to the distance of current and last (corrected) GPS record. The difference of
both distances may not exceed the specified value <dist_error>.

DEVICE.GPS.STARTUP=<mode>
Meaning
Turns on automatically the GPS engine during start-up.
Turns off the GPS engine during start-up. It remains
powered off until the GPS engine is powered up again via
PFAL command. The NMEA output protocols are also
switched off. Except $PFAL,Sys.GPS.Enable, all other GPS
related PFAL commands could not be executed.
DEVICE.GPS.AUTOCORRECT=<type>,<max_pdop>,<max_speed>,<dist_error>,<dropcount>
Meaning
Enables filtering of GPS auto corrections
Disables filtering of GPS auto corrections (default). In this
case, the followed values can be omitted.
