Wrong Time Stamp


I am using Parrot Sequoia Multispectral Sensor. A couple of days back, the Sunshine Sensor stopped working and we had a mission. So we went for data acquisition without sunshine sensor working.

Now, when I checked the images, the images when the Sunshine sensor was working fine are time-stamped correctly. Whereas, the images are not correctly time-stamped for the days my Sunshine sensor did not work.

The question is how to solve this issue.

Essentially, the timestamp used in the Sequoia is acquired from the GPS signal, meaning flying without it simply can’t provide a timestamp. My guess is that you just have to know when your first image was taken, and then to use that offset to apply a correction of the timestamp.
