Adam, I'm pretty sure you will have to manually install the solar filter, and remove it, before heading off into the woods.(correct me if I'm wrong).
Also, a backsite is just one more rtk, in the open shot. So, it's not too bad. Just imagining here.
I used to use a reflectorless Leica, set 2 L1 receivers up, on poles, with bloods, (one receiver sat all day, as I had a cluster of 3, then later 6).
I had DOT tape below the gps. Add 0.045' to each shot. With an atv, to rumble around, and carry it all.
I have manually carried it all, on foot, but it was a chore.
I think using J-mate robotically would be the bomb. It'd be nice if there were a strobe mounted on the J-mate, to assist the "rod-man" in choosing open slots to the J-mate.
My dad used to yell at me to wave my arms, to help him find me, at the gun. Without an inst. man, the strobe would help.
