Do you have any guide on how to integrate and shutter command with Pixhawk ?

And step-by-step process to geotag the images using results from PPS ?

Unfortunately you are just able to trigger the camera. The problem is, if your camera needs to focus there will be a delay between the trigger signal and the capture. I personally prefer using the feedback signal (flash signal) for logging. In my opinion this is the most accuarte method for synchronisation.


U can use a relay pin to trigger your camera. i used opto electronics in between to sepperate the curcits. I dont know which camera u are using? But u find some information on the web. Here is some infomration about relay pin configuration and trggering a canon power shot camera DSLR Cameras normally have trigger pins, so you dont have to hack the firmaware of your camera.

I also recommend to use some opto electronics inbetween to seperate the curcits.

Generally, PPS signal is not used to trigger a camera. The general solution is to enable the synchronization between the shutter to the flash. When the camera is taking a photo, a pulse is sent to the receiver through the PC (Prontor-Compur connection) port. port. The exact time when the photo is taken will be saved for post-processing.
