Abstract: Described herein are devices, systems, methods, and processes for determining the geo-positions of access points (APs) in a wireless network. The techniques involve utilizing geo-positioning data including global navigation satellite system (GNSS) measurements, wireless local area network (WLAN) signal measurements, air pressure measurements, preexisting knowledge, or any combination thereof. The GNSS measurements may include pseudo range measurements. The WLAN signal measurements can include time of arrival (ToA), channel state information (CSI), and/or received signal strength indicator (RSSI) measurements. The geo-position of each AP is calculated by applying Bayes' theorem to all available geo-positioning data and selecting the geo-position hypothesis with the highest probability. The geo-positions of the APs can be updated when a new measurement is obtained. The techniques can handle diverse AP deployments including heterogeneous APs with varying sensor capabilities.
