Sorry I missed this by reading in reverse cron order.
1) sudo is bad Security Theater(tm). Just be sure gpsd is run as root.
2) -F is for hotplug. RasPi serial IO knows nothing of hotplug
3) no /dev/pps0, so of course you get no PPS.
Try this, as root:
# gpsd /dev/ttyS0 -s 115200 -n /dev/ttyAMA0 /dev/pps0
Where did you see that is the way to do it? That needs to be nuked.
