Hi
That's great that new functions comes to the alexmoss gimbal. Is there a difference in quality of horizon drift correction when you compare to connection with pixhawk controllers on arducopter by mavlink?

I sow that this GPS has sd-card. I think that's good idea to develop new functions of such device. Dear Alex you can try to make GPS logger which will give possibility to geotag photos or post process them in PPK GPS routines to get cm level accuracy of geotagging of photos. Off corse you will need to install good gps inside like uBlox F9P. That's just an idea for entering new market :)
