OSHW+FOSS GPS or GPS+transmitter tracker?

[Jacob Hrbek]

   Looking for an OSHW+FOSS GPS or GPS+transmitter tracker does anyone
   know of any? The best i could find atm are:

     * [1]https://journals.plos.org/plosone/article?id=10.1371/journal.pon
       e.0267730
     * Ai-Thinker A9G

   Neither of which has libre firmware that i could see..
   Usecase is adding that to my escooter and to friend's portable gaming
   console so that the device can be located and retrieved in case of a
   theft so ideally it should include a reliable transmitter, but that can
   be a separate solution as it seems impossible to get a 4G thing and i
   am not sure if things such as NB,LoRa, etc.. can be reliable for
   tracking in the EU.
