Resumen
This research proposes a navigation system using BLE technology, which determines the position of an user based on the power of the signal received from a series of transmitters which are located in fixed locations. To interact with the system it was created a mobile application using flutter and firebase. The relation between the received signal strength and the distance to certain transmitter it was created a polynomial model as an alternative to the log distance path loss model that increases the accuracy of the calculated distance, specially for distances lower than three meters and greater than eleven meters. Finally, it was found that the min max trilateration method has better accuracy than the traditional trilateration method to determine the position from the distance to the reference nodes.
