Phone signals can help you find your way without GPS...

Existing telecommunications infrastructure could operate as a miniaturized global positioning system, offering submetre resolution in urban areas and indoors, where location information from satellites is often inaccurate.

I developed GPS navigation based on triangulation of signal strength from base stations 20 years ago to work for Nokia phones

False.

If you were intelligent enough to actually have achieved this then you
would present here in the group as significantly more intelligent than
you presently present.

You present as someone with an IQ of about 50 or less -- therefore it
is not possible for you to have achieved what you assert above based
upon the evidence of your postings here.

Try a more believable lie next time.

I don\'t know why, but this post really struck me as funny. It\'s especially so, because the author felt the need to hide his usual posting name, by using the name, \"Lie by a a\".

LOL, sometimes this group is just too fucking nuts!

I know there isn\'t much point, but here goes:
- GPS satellite navigation was already well established 20 years ago
- Triangulation based on signal strength from base stations does not give very
useful results because there are so many sources of variable attenuation
- I was able to get good distance measurements from various base stations
on a Nokia phone by reading out the timing advance data. This was available
when the phone was switched into engineering mode and gave results accurate
to a few hundred metres even when the base stations were many miles away.
It didn\'t need to be invented - it was built into the GSM specifications which were
developed in the 1980s.
- The network operators could do this without you knowing about it if, for example,
the police requested it. For a period of a few weeks around 22 years ago one of
the network operators regularly sent me digital maps showing everywhere I had
been with my phone based on timing advance data as part of a collaboration
with an equipment manufacturer.
It was surprising how good they were. We compared them with GPS data from
a car fitted with mobile phone and GPS navigation systems. It was just over 22
years ago that selective availability was turned off which made GPS useful for
ordinary users.
