5.2.2 AUTOSTART – Set Autostart Mode
Defines if PCM3292 automatically starts navigation when power is turned
on or PCM3292 is reset.
$PFST,AUTOSTART,<1|0>
<1|0> 1 to enable, 0 to disable autostart.
NOTE: In order for this message to have an effect, the new setting has to be stored in flash
memory by using the $PFST,STORE command.
NOTE: Since PCM3292 doesn’t save parameters in non-volatile memory,
AUTOSTART command has no effect in PCM3292
.

value
Description
1 BOOL 1 Position pinning on/off (1=on)
3 BOOL 1 Velocity smoothing on/off
4 BOOL 1 Position smoothing on/off
10 BOOL 1 Carrier smoothing on/off
17 BOOL 0 Route nav- & msg-task messages to host
(enables calculating the navigation fix in host)
45 WORD 12 Number of receiver channels
47 BOOL 0 Disable fast search (=> uses slower but more sensitive
search mode)
48 WORD 7000 Acq search window width (Hz, from middle of the
window)
50 DOUBLE 5 Timeout for resetting the post filters
51 DOUBLE 0.4 Coefficient for position smoothing, high
52 DOUBLE 0.12 Coefficient for position smoothing, low
53 DOUBLE 0.0001 Velocity filter coefficient, low limit
54 DOUBLE 0.5 Velocity filter coefficient, high limit
55 DOUBLE 3.0 Pinning lag criteria (meters). In pinning mode, the
position may lag behind the actual position by this
amount.
59 DOUBLE 1.0 Pinning velocity limit. Goes to pinning mode if
velocity is below this limit.
70 DOUBLE 50 FOM limit. Fix is marked invalid if FOM is larger than
this value.
71 DOUBLE 22 HDOP limit. Fix is marked invalid if HDOP is larger
than this value.
