Abstract: A method is provided that includes at each position of a plurality of positions along a trajectory of a first electronic device within an area: determining a range value corresponding to a distance between the first electronic device and a second electronic device, determining a pose of the first electronic device with respect to a reference coordinate system, and setting and storing an anchor point corresponding to the determined range value and pose. An update to an anchor point set for a current position of the first electronic device is received and the determined pose corresponding to one or more of the set anchor points is updated based on the update to the anchor point set for the current position of the first electronic device. A location of the second electronic device is estimated based on the range values and poses corresponding to the set anchor points.
