How to syn photo with external gps
I need more precision from gps for photogrammetric surveys.
I have a ublox f9p GNSS board with rtk/PPK correction, is very light and is easy to fix to my Mavic Air 2. The problem is to synchronize the shooting time of the photo and the time of storing the position with the external GPS.
My idea is to use a signal such as turning on the lower light at the time of taking the picture to memorize the gps rtk position.
Will be possible swicth on the light in syncro with the shot?

We don't have a command that controls the light right now, but even if we did, how would that work?
I'd like that the bottom white light switch ON when the camera shot a photo. After 1 second (or more but 1 sec is enought) the light switch off.
Whit an external light sensor I could record the gps position in an external gnss rtk board, at the moment of the shot.
the latency on commands is 50-200ms which will probably make this not feasible.
