Read GPS location from command line via SSH

While I found no solution using SSHelper, it is indeed possible using Termux and the Termux-API. No root is required.

After installing the Termux app, one has to install the Termux-packages openssh and termux-api:

$ pkg install openssh

$ pkg install termux-api

I also had to install the Termux-API app from Playstore or F-Droid to get it working.

The sshd config can be edited as desired and can be found at $PREFIX/etc/ssh/sshd_config.

Set a password for SSH authentication (or, alternatively and even better, public key authentication with ssh-keygen and ssh-copy-id):

$ passwd

Next, start the ssh server:

$ sshd

To stop the server:

$ pkill sshd

In my case it's on port 8022 per default. One should now have access to the Termux-API commands via ssh. termux-location retrieves GPS data as JSON. For example:

$ ssh [email protected] -p 8022 termux-location

{



"latitude": xx.xxxxxxxxxxxxxxxx,


"longitude": yy.yyyyyyyyyyyyyyyy,


"altitude": zzz.zzzzzzzzzzzz,


"accuracy": 64.31999969482422,


"vertical_accuracy": 192.0,


"bearing": 301.9921875,


"speed": 0.4399999976158142,


"elapsedMs": 8,


"provider": "gps"


}
