Re: ✘gpscsv

[Andreas B]

Hi Gary,

I like it. Any idea why time is not included in the -c SKY output?

$ python3 gpscsv -c SKY <ip:port>
# time,xdop,ydop,vdop,tdop,hdop,gdop,pdop
,0.37,0.35,0.75,0.47,0.51,1.02,0.91,

Is there any way to get number of sats seen and number of sats used out of this?

Best,
Andreas
