The sibling response here covers all of the points I would say. Scott Manley has a nice video covering the history of GPS and how it works, well worth a watch [VIDEO] It's not as simple as you think.

Don't mean to be rude, but your deep dives could be deeper. I clicked on 'How GPS works' expecting to see a certain Scott Manley video [0] there. Instead, it's 10 shorts I'd put firmly at the 'like n subscribe' end of the scale. Think I'll stick to my own curated list of creators for now. [0] [VIDEO]
