Position data of moving module?

[Analyzer]

Hi,

I would like to get position data from a moving module.I'm using an rf transmitter module in my pc side and using a rf receiver module in my moving module side.So, how can i know where my moving module is in my room and/or outdoor?

Hi,
I have not done this, but here's some opinions. I think it will be impossible to retrieve full tridimensional position using only one transmitter and one receiver. You will have to use a system similar with GPS, but at a lower scale. Basically, GPS satelites are moving above the target, this is why complexe algorythm are required to obtain position. If you will use stationery transmitters, your work will be far easy. But you cannot do it, only with at least three transmitters. Basic principle of retrieving position by RF means is triangulation.
