I have started a Python project here https://github.com/bigalnz/test_fft which uses a SDR (Software Defined Radio) to listen to Wildlife trackers and write data to a database about the state of the animals.
There is also some derived position data from the signal strength.
I am looking for some contributors to assist with parts of the project with are beyond me but its very interesting since it directly helps save animals and interfaces with real world hardware.
Please note this is a voluntary, non-profit project. If you would like to contribute please see the project page on github and contact me.
Thanks
