How to check if a USB GPS Receiver is working on macOS
I have a GPS receiver connected to VenusOS. It's a bit of last minute thing that I added to my system and the problem is it's not ideally placed. So I had to check on my mac if it was still working.
First, you will need
gpsd. A well coded unix tool to deal with GPS receiver
brew install gpsd
Then find your GPS receiver. It should appear as a USB serial device.
gpsd with the usb receiver as a parameter
gpsd /dev/tty.usbserial-14210 -p
cgps to see the data woming in live !
You also hae
xgps on linux for a graphical interface.
And voilà !
Like you can see on my screenshot, my receiver works but can't have a fix where it's palced. So I moved around until I found a place with good reception.
When you finished with debugging, kill the deamons 😈 !
killall -9 gpsd
If you wanna learn more on
gpsd or on GPS in general, I recommend using
man gpsd. There is so much good informations in there !
