[Ovmsdev] GPS flatbed alerts from military jamming/spoofing?

[Michael Balzer]

Craig,

to extract the essential data from your logs for analysis, simply do this:

cat log.* | { echo 
"time,dist,smoothed,alarm,gpsmode,satcount,hdop,gpsspeed" ; egrep 
"CheckTheft: vehicle parked.*hdop" | sed -Ee "s/\.[0-9]{3} .* dist/ 
dist/g" -e "s/ [a-z]+=/,/g"; } > hdop.csv

Attached is your CSV data & mine, with a new alarm today.

Your parking lot has pretty good GPS reception with never less than 7 
satellites in view, my case is near the edge of GPS unusability with 
some periods of only 2 satellites in view.

Regards,
Michael
