Does your GPS data include heading information? If yes you can simply
use it as Yaw value. Coordinates only won't help, since they won't
differ if the camera is rotated around itself. Most probably the jitter
will be much higher than the actual position differences.
Extract the heading and write it into a project file or papywizard XML
could even be automatized using exiftool in a script.
Happy new year anyone
