gpsd isn't the easiest thing to monitor from a phone, and I needed to check the state of the GPS on a little IoT thing I built.
Here's a hacky little python script to roughly approximate the output of cgps, but in a web page.
NB: in the same way that gpsd only listens to localhost by default, this server also only listens on localhost by default.
NB: If you're planning on using this with a ublox-based receiver aboard an aircraft I suggest you configure the dynamics mode to "Aircraft <1g" or else the receiver will constantly reset.
usage: webcgps.py [-h] [-g GPSD] [-i SEC] [-l LISTEN] [-p PORT] [-t SEC] [-v]
options:
-h, --help show this help message and exit
-g GPSD, --gpsd GPSD [gpsd://localhost:2947/dev/ttyACM0]
-i SEC, --web-refresh-interval SEC how often the web page updates in seconds [2.0]
-l LISTEN, --listen LISTEN [127.0.0.1]
-p PORT, --port PORT [4773]
-t SEC, --timeout SEC GPSD socket timeout in seconds [3]
-v, --verbose [0]
There's also a helper script - gpsreset.sh that can effectively unplug and replug your gps if it somehow gets horribly confused. Using the included gpsreset.service systemd service you can just automate that process. Terrible, terrible kludge, but it's better than data loss.
