Hi, How realistic would it be to locate an object on a field using signal=20 strength? I'm thinking the (moving) object would transmit (LoRa?) and=20 there would be receivers around the field. At first pass, I'm thinking the transmitter would send numbers (changes=20 each on each transmission), and the receivers can record the signal=20 strengths when they receive each value, then correlate those values to=20 get a location. I'm just not sure how realistic it would be to get the position of the=20 object to within say a few feet. No, GPS is not a workable option for this.
