its not a problem to use GPS to figure out the location of the antennas. But I have to know the location of the bluetooth device, which does not come with GPS.
If the minimod is around 1575.42 Mhz. So I was thinking of using GPS time to calculate the time lapse between when the bluetooth signal initiates from the antenna to when the signal returns after detecting a bluetooth device.
If the bluetooth device is 1m away from the antenna, it would take 6.66e-9 seconds for the entire trip. Meanwhile the GPS is updating itself 1.575e10 times per second. At that rate and at that time, it updates 1.575e10*6.66e-9=105 times.
So even from a meter away, the GPS would still be fairly accurate in the time lapse.
You talked about once-per-second GPS time pulse, but isn’t the frequency of a GPS the number of pulses per second? 1575.Mhz would be a lot of pulses wouldn’t it?
Would this method work?
