A method for determining a geo-location of a target station. The method includes transmitting a plurality of ranging packets to a target station and receiving a plurality of response packets transmitted by the target station in response. A plurality of round-trip times (RTTs) are determined based on the ranging packets and the response packets. A plurality of angles of arrival (AOAs) are determined based on the response packets. First and second pluralities of squared residuals are calculated for the plurality of RTTs and the plurality of AOAs, respectively. A third plurality of squared residuals is generated by summing the first and second pluralities. A minimum of a sum of the third plurality is calculated to identify best-fit location parameters for the target station. A circular error probability (CEP) ellipse is generated using the best-fit location parameters and a geo-location of the target station is determined based on the CEP ellipse.

Existing device localization strategies can lead to significant localization errors due to clock synchronization discrepancies among network devices. To address this, devices, systems, methods, and processes for facilitating device localization independent of clock synchronization are described herein. A reference network device coupled to multiple peer devices receives a blink signal from a wireless transceiver and a set of notifications from the peer devices. The set of notifications indicates arrival and processing time durations of the blink signal at respective peer devices. The reference network device assesses a latency value associated with each of the set of notifications and estimates time difference of arrivals (TDoAs) for the blink signal based on a clock of the reference network device and the assessed latency values. The reference AP determines a location of the wireless transceiver based on the TDoAs estimated without clock synchronization between the reference network device and the peer devices.
