A method is provided for determining the position of a mobile technology platform within a structure, wherein the mobile technology platform is equipped with a gyroscope, a magnetometer and at least one accelerometer. The method includes deploying a set of RF (radio frequency) beacons within the structure, wherein each RF beacon emits an RF signal; recording, at each of a set of sampling locations within the structure, the RF signature created by the RF signals received at the location; forming an RF fingerprint of the structure from the recorded RF signatures; and using the RF fingerprint, in conjunction with readings from the gyroscope, magnetometer and at least one accelerometer to determine the location of the device within the structure.
