Precis-BX316 GNSS RTK Board (GPS L1L2/GLONASS G1G2/BEIDOU B1B2 with Heading) supports PPS output, which is useful in shutter synchronization. More details, click here.
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 ?
with Event Mark no works?
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 www.tuffwing.com. 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.
@Waladi 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.
