I did not misspeak. I linked to a-gps which explains how the system works.
You do not need to transmit or receive cell data to receive a GPS signal. If you use GPS isolated, your location isn't leaked.
But that's irrelevant because if you use cellular data, the cell tower knows approximately where you are.
I have been using GPS since before cell phones had data. My boss back in 1994 brought in the man who wrote the accuracy encryption part of gps (that has since been turned off) to give a talk on the encryption that used to be in GPS to myself and my coworker just for the fun of it because they were old friends.
Misspeaking is not the same as misunderstanding.
"I didn't say GPS needs cell towers"
How is that a misspeak?
Does GPS need cell towers? Yes or no.
Because I explicitly said that GPS does not need cell towers and you claimed I misspoke.
GPS does NOT need them to be "faster" for what an end user expects.
Cold start is 2-4 minutes.

Waiting 4 minutes for your phone to show your location the first time you click your map app would be unacceptable for most people today. Agps ameliorates that delay.
But that's irrelevant to my statement that "GPS doesn't need cell phone." Which you claim is a misspeak.
