Steve,<br>
<br>
a) did you pick an active GPS antenna? I.e. one with a voltage on
the label. The module can barely get a signal with passive antennas.<br>
<br>
b) If you restart the modem, wait for "State: PoweredOff" before
starting it again.<br>
<br>
c) You can monitor the NMEA sentences by setting <font
face="monospace">log level verbose gsm-nmea</font>.<br>
<br>
d) Not getting PPP as well may point to a general modem issue, maybe
also log gsm-mux & simcom to check for that.<br>
<br>

<div>I'm running with the ABRP script - is it possible that
this is impacting the reliability? </div>
