Hi Simon. With what accuracy did you end up? Vertical and horizontal? Just to understand correcly, both the phantom and Reach get their time from the satellite? (I thought the drone might sync with your device/phone/ipad`s time). But then the only problem is that the time “zones” differ from the 2 devices? How do you actually sync the photos and coordinates? I thought of writing a small program that will just run in a loop and add every photos name next to the coordinate in a txt file. That in turn should be up-loadable to Pix4d in the “add EXIF” section.
