Hey all, I am working on a new project where I need to get a position, basically in millimeters, using 4 transmitters and a receiver. Right now the problem that I am having is that to triangulate position there are two methods that I know, first off you can use signal strength (my preferred one) to determine is, however I am not entirely sure what hardware is commonly used today to get a measurement of signal strength. The other is based on time, basically however long it takes for the radio wave to reach the receiver. I am working in a small room, about 50 meters, and want to get an accurate measurement. Considering radio waves move at the speed of light, I can't get a good timer that can respond within microseconds. So basically here is the question, does anyone know another method of doing this? And if not, is there a way to implement the timed based method? Also, where can I find a signal meter? Thanks
