Does pole height affect GNSS accuracy?

It can affect it if the pole is low enough that your body or something else forms an obstruction. I didn't watch the whole video. He lost me when he set up that short arrangement in front of a building that will surely block at least a whole quadrant of the sky. You should be thinking about how signals travel to the antenna--they can bounce off the ground too. 

He is me. The intent of the test was not to test only ideal situations but performing testing with a variety of obstructions nearby.

Nicely done.  Long gone are the days of a single constellation and poor solutions to multipath.  The main takeaway from this video is at approximately 5.5 minutes in.

Very interesting, my typical work involves traveling by commercial flight to a project, and I am always worried that the airline will "lose" my bag with a 2 m rover pole and tripod. Not very common for this to happen, and when it does they typically put it on the next flight. But it does happen. Also, when going outside the US, I would prefer not to have the long bright orange rover pole canvas bag with me to draw attention when going through customs. Last trip to Ecuador in the summer of 2025 I used a collapsible rover pole (30 cm segments) with no tripod. Fit perfectly in my suitcase and backpack. I was not doing longer "Observed control" observations, so it didn't really matter that I didn't have the tripod (which only collapses to about 1 m). But, within 15 minutes I had broken the rover pole at one of the joints. I used a rebar and duct tape for a field repair but it was still a hassle. So I returned that. 

It wouldn't work for a lot of my projects (in very rural areas, dirt roads, etc) but it would be a good option to have.  

I like your idea of a packable mounting arrangement, but I think that little three point gadget is over doing it a bit. It is intended for use on a nominally flat deck and may not have the adjustability to be used in rough terrain. There are very short rod/bipod combos that would do the job nicely.

There's always this...

@jim-frame You hiding a 2' tall munchkin surveyor behind that white screen?

I cut down that tripod mostly for fun, but there have been a couple of situations over the years in which I could have used it.

I recall an article in one of the trade magazines many years ago where an outfit had cut down some tripods like that so they could traverse up a 6' culvert pipe.

that's what the mask is for. I have a new habit. When close to a building I put my hand up along side the head between the building and me. Helps dial in the sensors as the multipath goes from 6 feet away to the radius of the globe you are using. IE Tight enough for gnss

Edit: I could be wrong but was a physics major with training in EMF before that.

In reference only to the ground causing multipath interference mentioned above. There is a shield but in to your head units. Thin metal plate on the bottom. I doubt it's effectiveness based on 1/4;wavelgths of frequencies but the aluminum shell may help that.b

 

But electronically you can set your elevation mask to whatever degree you want. It will reduce number of satellites you receive data from so have to consider constellation location if you are upping it past 20°
