"Hi Felipe, the Mission planner issue is normal it doesn’t really matter is just the way mission planner displays it in, so it should be no problem. what type of flight controller do you have? (Pixhawk 1, the cube?) could you post you parameter file?…"

"Any luck with this? I also have an ADC Lite which would benefit from this. A question for you, how are you currently geotagging? Mission planner is not working for me since it seems pixel wrench strips the EXIF information and changes the file time…"

"So for those interested in the quality and precision of using a GoPro for survey work, we made a comparison using direct survey techniques, a drone with a 24 Mpx camera and a Drone with a GoPro. I presented some results at Dronecon and my talk is…"

"I think one more parameter you should add to your responses is the ASL you fly in. It makes a very big difference in flight time at sea level, vs 1500 m ASL."

"If you are not using the Y6 send it to me :)"

"You should use the .log file. This is the log that contains the GPS track for the vehicle. This log is also better that the tlog, as you may loose comms and the tlog may be incomplete."

"Did you try checking the wiki??

"With out having the pictures and the original log file I can't tell for sure, but I think you calculated offset is incorrect. The locations on the pictures seem to show that the vehicle does not get off the ground until these pictures:

"That would be so easy if the camera actually triggered every time that the APM told it. But since there is no actual feedback from the camera the APM may tell it to trigger and it does not actually trigger. I have tried both ways and I always find…"

"I think you can detect large errors easily, once the geotagging is done there is a KML file generated, you can open that in google earth and when you put your mouse over one of the pictures, you can see if it matches the location. But for small…"

"The log offsets shown tell Mission Planner the position of each item in the log file. So the time is the second item, latitude the 6th item and so on. 
Currently on the new version of mission planner I had not had to modify these anymore. The…"

"Have you calibrated the ESCs? since the motors spin at low revolutions when doing the motor test. Sometimes if the ESCs have not been calibrated, they will not spin."

"Why did you have to write a script? could't you just adjust the geotag offset in Mission planner? or did you find a problem with that?
Also if your tlogs are not accurate or you lost comms at some point you will have data missing and in that case…"
