1. A non-transitory machine-readable medium storing a program executable by at least one processing unit of a device comprising a first sensor and a second sensor, the program comprising sets of instructions for:

  • receiving, from the first sensor, a first set of sensor data that the first sensor detects from a first set of signal-transmitting devices;

    receiving, from the second sensor, a second set of sensor data that the second sensor detects from a second set of signal-transmitting devices;

    processing the first set of sensor data to determine a first set of potential locations and a corresponding first set of location metrics associated with the first set of potential locations;

    processing the second set of sensor data to determine a second set of potential locations and a corresponding second set of location metrics associated with the second set of potential locations; and

    identifying a location from the first and second sets of potential locations as a location of the device based on the first and second sets of location metrics; and

    filtering the first and second sets of sensor data; and

    performing smoothing operations on the first and second sets of sensor data; and

    wherein the location metrics associated with the first set of potential locations are determined based on reference data associated with a plurality of reference locations.
