I would like to extract in GPS coordinates (Latitude, longitude, and height) the complete trajectory of a fly, but I do not want to set any waypoints. If I use telemetry, I know it is possible to get the different logs to find the complete mission. However, I don't want to use telemetry. I have been looking at different apps but haven't found anything so far. I will attach the phone to the drone to record the mission.
Any help is appreciated.
