Nice article and lovely piece of kit that one from sparkfun. Will likely be getting one next year to further my experiments with gunshot localization, on my Pi-based sound localization platform (https://github.com/hcfman/sbts-aru https://github.com/hcfman/sbts-aru). Though at the distances I'm localizing the phone based GNSS seems to be working quite well. With an RTk GNSS though I could do some experiments with localizing bat calls. I've tested the Pettersson Ultrasonic microphones with my localization platform and that works fine. I suspect that the bat localization I could achieve if my co-ordinates had RTK accuracy would be pretty damned good! But I have to try it to know.
