I just saw a segment on the Science Channel by Beyond Tomorrow about Kinetic
GPS. They claim 1000 times speed and sensitivity. Doing a Google search
didn't bring up much on kinetic gps.

Anyone got more info on this?

Accuracy of positioning - yes.

What the heck do they mean by "speed and sensitivity"?

They implied that their processor samples GPS signals 1000 times faster than
standard GPS devices and as a result they can obtain the equivalent of 1000
times the sensitivity.

The correct name of the company is:

QinetiQ

The product is the Q20

=============

It's definitely NOT RTK.

So it is not a "high accuracy" gps - in fact the accuracy specs for
the gps module from this company are not quite as good as my 76csx,
and the acquisition times are identical - hmmmm!

It does purport to work indoors, but the stated accuracy goes from 5m
typical to 50m typical, according to their specs, so why bother.

The fastest (and only) update rate I found in any of their specs was
in one module, which was "15.625 Hz (64 mS) inc. raw data (code and
carrier)".

Even Trimble systems using Trimble RTK receivers capable of 20 Hz
position estimates tell you not to set the update rate to any faster
than 10 Hz or it won't work properly (GCS900).

It seems this is just some more ho-hum misinformative marketing
hoopla!

But it does have very impressive sensitivity, 189 db, against more
typical 150-160 db of most GPS units. If they actually achieve that, it
is pretty useful in many applications.

dBw? dBm?

==============
-189dBW tracking
-185dBW acquisition
(hot or assisted, Ephemeris available)
-174dBW unassisted acquisition
(Ephemeris decoded)
==============
Sirf 3 is -159 dBm.
==============
What's the difference between the 2 specs?

Thanks, Yes this is apparently the technology that I was looking for.

On the TV program they demonstrated it working from a briefcase inside a car
and also inside a building.

I am really disappointed with the capability of current consumer GPS units
and always hoping for better.

Conversions of power levels between W, dBW and dBm.
http://www.giangrandi.ch/electronics...l/decibel.html

-189 dBw is equivalent to -159 dBm
