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.

Point totally missed.

GPS was designed to be a locating system, period.

The fact that a locating system doesn't provide user tracking or
warm up muffins is irrelevant.

The US military (and probably all the other major militaries) have
troop tracking systems.

And guess what, the tracking systems don't provide location data or
warm muffins either. GPS provides the location data.

It's a system that allows users to locate themselves. It doesn't provide any
information to third parties.

No ****?

How about classical music, weather, satellite photos, talk radio,
wireless internet, baseball scores?

As I said, GPS was designed to be a locating system, as in where the
**** am I, period.

Imagine what would happen if the GPS infornmation could automatically be
transmitted somewhere else........... Oh wait, that does happen.

How interesting. Transponders transmit the planes location obtained from a GPS
receiver.

Transponders are not part of GPS. I can write my location on a notepad, but
that doesn't make my notepad part of GPS, either.

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.
