[QUOTE="mha1, post: 79030, member: 12174"] Just curious.There is a difference between a track error and a heading error. Your video is helpful to decide what it actually is. It looks like you are in an auto mission. So the drone does all the navigating to keep it on the track (the straight line) between the start and end point (your POI). It looks like the drone hits the POI dead on. This means there was no track error. If there had been one the drone would have been off to the right or left of the POI. It looks more like a heading error meaning there is an angle between the actual heading and the track angle (nose not pointing along the flight path). Assuming there is a well calibrated compass (heading reference) there is no reason to believe the nose is not pointing along the track. I can only think of the camera being slightly off. Either mechanically or due to the way the yaw axis is digitally stabilized. Remember how this is done. A 1920x1080 crop of the 3840x2160 sensor is dynamically positioned to act as a digital yaw gimbal. There is no guarantee the crop is always near the center of the sensor.
