Re: Relative Positioning

If I take an RF transmitter (A) and an RF receiver (B) and I precisely
record the time it takes for the the signal to get from A to B, I
wonder how accurate the distance measurement would be. If I moved A
1mm away from B, would the recorded time accurately represent the
change in distance?


Lots more helpful responses. It sounds like it will be very difficult
to achieve. It seems strange that we can get accuracy to a meter with
transceivers flying 20,000 kilometers above the earth (GPS) but we
can't get accuracy to a millimeter in a system where the transceivers
are all a couple feet from each other.

Thank you for all the help,

Matt
