So I recently created a fairly detailed waypoint mission for litchi to test out some POI shooting and then at the end do some reveals and some other effects for learning purposes. I created one big mission with everything in there. I figured it would be some time before I got to test it out since the weather here has been horrible. Well yesterday the rain let up for a little bit so I took the P3S to the park and ran the mission. I recoded the screen from Litchi so I could watch it and see how it did. The winds where fairly high at 11 mph with gusts up to 18 mph - but I was surprised how well the drone flew and remained calm.
The first part of the mission flies around the park and points at different areas at 150 feet. I was watching the drone and the iPhone to ensure it stayed at the same altitude. The later part of the mission goes down to 50 feet at one point and then 10 feet for another. During the first part at 150 I noticed it seemed to be rising at one point (see video at around 2:35). The iPhone altitude didn't show any height rising and I figured the wind just blew it off it's course and it went back and corrected itself. But when it came for the lower parts of the mission, you can tell the altitude was way off. I tested it when landing it from where it took off and on landing it showed that it was at -15 feet.
I know the P3S is not that sophisticated and basically puts takeoff point at 0 and used GPS to determine height. But how can it be 15 feet off when it returns? Also, are the newer drones (Mavic and P4) better at lower level altitude since they have ultrasonic sensors? Still waiting for my Mavic to arrive and wanted to know if this issue would be there as well.
