Hello there, I have been looking for a trilateration algorithm for my school thesis considering having and I use Estimote beacons.
My undestanding is that for trilateration you need 3 beacons. However your Indoor Location App is working with 4+ beacons I am a bit confused. Do you trilaterate with the 4 beacons at the same time? How? Or do you use a trilateration of 3 beacons having the 4th beacon measurement to somehow correct the final result?
Could you explain which mathematical formulas do you use? Thank you for your response.
