A GPS receiver doesn't broadcast its location. GPS works purely by analyzing the signals received from satellites. This is probably a design goal for military use, as well as a consequence of power requirements.
Yes. But a jammer will draw a Hellfire.
There is no such thing as a GPS frequency.
WCDMA phones the location service is defined in terms of messages on
I beg to differ, there are (perhaps >1) RF freq assigned to the Constellation. It seems that for CDMA or the
normal network layer, see a Google search for "position determination service order".
Yes its cheaper and allowed (for now) to triangulate (to what, 100m?) using physics; but GPS will become cheaper and cheaper.
