Thanks for the further detail. Unfortunately, I don't understand. For example, check out this screenshot from the OP: https://i.imgur.com/9kh5tBi.png https://i.imgur.com/9kh5tBi.png If the satellites are above (the horizon/field of view), and you're intersecting spheres, it seems to me that you would have the best precision in the height direction and worse precision along the sphere. Am I missing something?
