Funny, GPS can place a smart bomb right on a target it tracks, but it
can't track aircraft. I have news for you. I was on an international
flight a while back and was talking to the relief pilot. He said the
US was the only country NOT using GPS and was totally outdated. So
how, then, do the flights get to where they're going?



GPS was used to guide the bombs to pre-determined fixed locations, which
is a bit different than how it would work with aircraft.

To use GPS for tracking an aircraft, the GPS device would be on the
aircraft being tracked and it would have to broadcast this location
information to the trackers.

True, but GPS is GPS. They all use the same satellites.

Yes, but GPS is useless for tracking, and that is by design.

Do you ever have one clue about what you're posting. See below:

A GPS tracking unit is a device that uses the Global Positioning
System to determine the precise location of a vehicle, person, or
other asset to which it is attached and to record the position of the
asset at regular intervals. The recorded location data can be stored
within the tracking unit, or it may be transmitted to a central
location data base, or internet-connected computer, using a cellular
(GPRS), radio, or satellite modem embedded in the unit. This allows
the asset's location to be displayed against a map backdrop either in
real-time or when analysing the track later, using customized
software.

That is a system that uses a GPS receiver as one of its components. GPS
itself does not provide tracking. The DoD deliberately designed it that way.

That's like saying a Ford F-150 pickup truck can't be used as a ski
boat because Ford deliberately designed it that way.

Not quite. The GPS is a receive-only system. It allows users to determine
their positions without transmitting anything to anyone, which provides
stealth and also gives the system unlimited user capacity. There isn't any
way to get a transmission function out of GPS. All tracking systems are more
complex systems in which GPS merely plays one part.

This was all by design. The DoD wanted the capacity and didn't want their
troups to give themselves away every time they checked their positions.

That stupid. The whole system being built is a GPS tracking system to
space and direct flight paths. Your comments are completely erroneous
and stupid. Which, of course, won't stop you from babbling on. Just
watcj.

As I've already explained, GPS does not provide tracking. What is being built
is a system that uses GPS to determine position, but that is all. The rest is
independent of GPS.

Why don't you read what he wrote? "A GPS tracking unit is a device that uses
the Global Positioning System ..."

I did, but he apparently did not, since he seems to think that the GPS itself
provides a tracking function, which is a common and rather serious
misconception. Nothing in GPS allows a user to be tracked.
