Let me clarify.
I have used each of the services and devices at varying times.
I have had a cell phone (of one type or another) since 1999.
What I have found is the GPS and the cell phone lost signal at roughly the same time.
While correlation =/= causation, I find it highly suspect and tend to side with the idea it is indeed more likely that GPS tracking and cellular service is occurring at roughly the same altitude (i.e., the height of the average cell phone tower).
I'm sorry for not being more explicit in my previous post.
"As you don't go into any detail of your setup, this doesn't prove/disprove anything." was meant to encourage you to provide more detail.
To get from correlation to causation one would e.g. need to know:
- Can the effect be reproduced reliably (same/other locations/tines)?
- Can the effect be reproduced with different phones/GPS?
- Do both devices always loose signals at the same time? Or does is it sometimes only one or the other?
- Is the signal really lost or just "useless"? (e.g. GPS not getting enough satellites to triangulate or mobile phone getting wrong provider)
- Where does and where doesn't it happen? => What might be possible reasons?
- Why would that suggest the same altitude? (Average height of a cell phone tower isn't really a useful concept => on building, on hills, on mountains, ...)
I have had a cell phone (of one type or another) since at least 1994 - so what does that fact add to the discussion?

It means you are saying 36,000 km far from earth satellite are suitable for telling out location but 1 km far from my location installed tower aren't? I have studied Architect Engineering and I know how to draw map for buildings and roads. Everything in map is benchmark to each other like one signal tower to other and so on. Now if you ask me I can draw map and create my own GPS for my city. I will draw map of my city and specify 1km=cm/inch (unit set). now I will mark each signal tower as benchmark and whoever getting signal from will be traced like how far he is from signal tower and in which direction.
In 2002/2003 I shocked when I saw my town location right under time on my mobile (Samsung c220) in Pakistan. And this location was definitely took from signal towers. Also if smartphones are taking location from satellite then how my Old desktop showing my location on my Google Chrome Browser? Definitely from my router. right? but my router is connected through optical fibre with my internet providers server my question is how they are tracing my location?
Only Answer came in my mind is: My IP location which benchmarks my routers location on map? Correct me if I am not wrong.
