General / How is the EXIF data from Drone/UAV/UAS obtained by the on-board GPS

« on: September 21, 2016, 03:46:17 PM »

I have a Phantom 3 4k UAV and I use the EXIF data to align my photography in Agisoft. Does anyone know how exactly the geotag is established for each photo? Does it take a new coordinate each time a photo is taken and if so how does it know where its position is if it is moving and tilting as it does not have differential GPS?
