Clearly you didn’t… You keep asserting false statements that have already been disproven with sources.

But ultimately it’s the same thing. You need 4 pieces of input. Either 3 satellites AND elevation. Or 4 satellites.

If a watch doesn’t “know” elevation (barometer or other sensor providing such information) as the fourth data point… Then it NEEDS 4 satellites to make the data points whole. Making your statements yet again wrong. I’ve covered the cases… but you keep pushing false statements like “gps is triangulation” (completely incorrect) or “GPS uses 3 satellites” which is also only correct in one very specific case… Where it’s largely 4 or more, with reality being more like as many satellites as the device can read the pulses for. Often being a dozen or even more…

I am making accurate and complete statements. You are the one peddling misinformation.

Hell to prove the point… my time server grabs GPS as it’s primary source. It grabs up to 12 satellites to sync time. It shows me my sync status for lat/long as well… At 3 satellites it CANNOT get a lock for location OR time. At 4 it gets a weak lock.
