Re: gpsd with python project

[Al Grant]

Thanks all for the replies.

I should have mentioned that I will deploy the unit in two ways (1) on
a drone for logging data and (2) static deployment - although I will
still have a gps attached.

I have noted from the replies not to write to the SD, and upgrade to
3.24 for best support with ublox (although I seem to have the daemon
working on 3.22 ok thanks - perhaps this helped
https://stfn.pl/blog/08-gpsd-linux-ublox/ )

Will look at sending the data via websockets and tailscape to my server).

The other option for my GPS is to use a active antenna with my Quectel
EC25 ceullar pi hat - i say active because the performance of the free
antenna I got with the Sixfab EC25 based GPS was terrible). Maybe a
siretta one like Alpha 4A.

Thanks again for all the input.

Al
