I assume your ceiling was more than 4 m high?
We’re using some fairly solid tripods so unless the wind is strong enough to push them over (takes gusts of about 40 mph as we discovered once) there isn’t much sway. Final solutions we’ll be fixed to the walls so height won’t be an issue from that point of view.
Our biggest concern when it came to height ended up being getting enough vertical diversity to get a meaningful height calculation. Turns out using 8 anchors spread out over a 30x100 m area you can actually get a noisy but usable height value with only 1 meter in variation of anchor height.
