Gpsd
What and why
gpsd is a service that listens to one or more gps receivers and makes the received data available over a network connection. It understands a wide variety of binary protocols.
What you get with gpsd
Besides the daemon "gpsd", of course...
In /usr/local/bin, you will find
- lcdgps
- gpxlogger
- gpspipe
- gpsmon
- gpsdecode
- gpsctl
- cgps
Position
Time
I will be running gpsd in a docker container on Bellman to set up my Magnavox reference station.
docker pull forcedinductionz/docker-gpsd docker run -it -p 2947:2947 --device=/dev/ttyAMA0 forcedinductionz/docker-gpsd -D2 /dev/ttyAMA0
By using docker I avoid installation issues of getting it going on a Mac. I still have to configure it. Not able to do that at the moment. (My GPS receiver is packed in a box.)
Grove GPS, for Kali
I am putting a GroveGPS (from M5Stack) on a Pi 5, so it can talk to the Kismet data logger. See also WiFi Wireless Projects.
I had to edit /boot/cmdline.txt to remove the serial port from the console.
apt install gpsd gpsd-clients systemctl enable gpsd.service
Edit /etc/default/gpsd to specify settings. DEVICE is probably is /dev/ttyAMA10 and speed should be set to 9600 normally but gpsd can figure that part out.
See if it's working.
Python integration
I need to put a short python script here...
