It’s not really relevant to how GPS works? It’s just scene setting an intuition for, crudely, how you might estimate your position relative to landmarks.
If your take is then ‘well, he didn’t rigorously define how he derived the error bounds on crude position estimation, therefore all this stuff building into the level of precision GPS is capable of rests on a flimsy foundation of lies’, perhaps you are not the target audience for this kind of didactic presentation.

I think running into a nonsensical, unexplained diagram is a good heuristic for whether or not an article is worth reading — even if, in this case, it turns out the rest of the article is well-written.
- jameshart 5y agoSounds to me like you ran into a strong counterexample that suggests it’s a terrible heuristic.
