Probably a 5G antenna. Looks like a Ligado logo on the side????
I never looked at it that way before, but it stands to reason that the most extreme peak on the globe would demonstrate the most extreme effects from even minute changes. Everst?ÿis likely subject to a more extreme version of settlement/subsidence than anywhere else on the planet (above water, anyway).
I have not seen anything yet at the ?ÿlevel of technical detail I want.
Of the many recent articles I like this best:
https://www.npr.org/2020/11/24/938736955/how-tall-is-mount-everest-hint-its-changing
So much better than other stories I've seen on it.
A nine prism array, pointing down to an instrument measuring up the mountain.?ÿ
I spent a lot of time doing the same, of course not at 29,000'.?ÿ
We would raise a 4' tall electric conduit pipe, set an orange painted gallon ice cream bucket over it with center cut holes for the pipe and set a prism array in the pipe. Sometimes up to 12 prisms-4 sets of triples. Then measure to it from up to 30,000' away. The ice cream bucket would really shine. Verticals taken to the 4' mark. All with a T2 and HP distance meter.?ÿ
The reason here would be some kind of check to the gravity measurements I assume. A lot of equipment to carry to the top of Everest.?ÿ
Gravity would be hard to do on the ground due to the snow load, movement,lack of heat(L&R meters and Scintrex CG-5s wouldn't have enough power to stay warm) nor would it be feasible to load up a MicroG A10 or FG-5due to the same conditions. Better and safer to just fly it and stay warm.?ÿ IMHO.?ÿ ?????ÿ
