Mobile sensorgnome

I’m reading a couple of other posts here asking about magnetic mount antennas for mobile use and even SG use in aircraft. I’m assuming this means the SG is capable of receiving tags while providing an accurate location fix while in motion? I’m building a SG now, and assumed that it needed to remain in one place once registered. Does this mean I can throw it in the trunk of my car and with external antennas (cut to correct frequencies) collect data as I travel?

Heh, someone always tries to push the boundaries :joy:

The /etc/sensorgnome/acquisitions.json file has a seconds between fixes value. That drives the rate at which the SG queries the GPS and if it gets a fix writes the coords into the data files. Be careful changing that and check that the resulting data files look the way you expect. (You need to systemctl restart sg-control after editing the file.)

I can’t speak to what the Motus back-end will do with all that info. I believe there is a way to mark a station as mobile…

Happy experimenting! But please do some testing before you head out and expect everything to just work…

Hi Michael, you got it. The “mobile” status is set at the deployment level. So you’ll create your station, then when you create a deployment to add your receiver to it, you’ll see an option to select type. Ground-based vehicle is what you want.

Note that the main thing this does is bypass some of the location based data validation and alerts in your Data Issues page that normally would be triggered if a particular station moved so much. And of course, it reminds the operator (and others, if their tag happens to be detected by it) that thing is actually moving!

Would a station on a marine vessel also be a ground-based vehicle? It probably doesn’t matter that much, but for offshore vessel-based Motus stations, it seems a bit funny to classify them as ground-based.

There is a “ship” option which should work in these cases.

Fantastic info guys, thanks!
