Abstract
Devices, systems, methods, and processes for calibrating clock signals of network devices are described herein. A device can initiate a ranging procedure with a reference device for synchronizing a clock signal of the device. The ranging procedure may utilize Fine Time Measurement (FTM), Ultra-Wide band (UWB), or similar protocols. The device can also synchronize the clock signal based on detection of ambient interference events. The device may also receive Global Navigation Satellite System (GNSS) data from a satellite and determine a pseudo range for the corresponding satellite based on the synchronized clock signal. The device may further transmit the GNSS data to a location engine. The location engine may aggregate the GNSS data received from a plurality of devices and determine a geolocation of the plurality of devices based on the aggregated GNSS data.
