Yes, thats the only way I can see it done too.
Do you have any suggestions on this subject?
...or even if its possible with a students budget?
If im not wrong the GSM-location services uses radio time-of-flight, though that accuracy is worthless inside a house.
So, the time-measuring needs to be very exact and the TDC-GP1(**broken link removed**) seems like a good start:
* 2 measuring ranges ---a: 2 ns -7.6 µs --- b: 60 ns-200 ms
* 2 measuring channels with a resolution of approx. 250ps, optional high resolution mode with one channel and approx. 125 ps resolution
Though, I suppose the price on a unit like this is out of my budget(anyone know?) but it may be possible to retrieve a sample-unit.
On acam's page there is some design suggestions using lasers ans such too...
But, the time measuring is like the only thing I do have a clue on, the actual radio-emitter needs to emit a VERY accurate pulse, and maybe a powerful one too?
...any suggestions, please?
Thanks for your answers so far
