Another worry that I forgot to mention: Wondering how flying around my house with lots of tree cover is going to affect drone hovering in Tripod mode? Even if good GPS coverage is rapidly lost and gained, does the DJI IMU keep the drone steady or basically, if without good GPS the drone drifts in the wind, will I be counting on obstacle avoidance to keep me away from bad stuff? Have no good overall idea how GPS and IMU interact to let drone hover. Is IMU just all about which way is UP? If there is a great video or text explanation somewhere of how GPS, IMU, and COMPASS all work together that would really help me. The other thing, at least in my Mavic 2 manual, although DJI gives visual angles of detection for the sensors and detection ranges, it gives no good explanation of how close to an object along any axis one is going to come before the sensors tell the drone to stop and hover - and it doesn't mention if those parameters are adjustable limits. So, IMHO, while the Mavic 2 Pro is an incredible piece of tech at an incredible price point for what you get, DJI, as far as teaching one everything you really need to know about it to fly it safely as a rank beginner comes up a bit short.
On the tree foliage, perhaps a Texas live oak is so sparsely foliated as compared to an East Cost red or white oak or maple that I don't need to worry too much about loss of GPS signal under live oaks? We shall see .... The trees in my yard are usually relatively starved for water and not fully foliated as it costs a fortune to irrigate one's yard profusely, as it should to help conserve resources. |
