Abstract: A system and method for proximity determination can include receiving an RF signal transmitted from a target location, the receiving performed by an antenna of an autonomous moving device, extracting received signal strength indicator (RSSI) values by processing the received RF signal, receiving distance measurements provided by a sensor associated with the autonomous moving device and storing the distance measurements in the memory of the autonomous device. The extracted RSSI values can be correlated the with the distance measurements to obtain a proximity value. A distance to the target location can be determined based on the proximity values.
