METHODS FOR SYNCHRONIZING MULTIPLE DEVICES AND DETERMINING LOCATION BASED ON THE SYNCHRONIZED DEVICES
Methods for synchronizing multiple transceivers to a single master clock are provided including broadcasting a message from a master device, the broadcasted message including a device identification number identifying the master device to at least one known device within range of the master device; receiving the message at the at least one other known device and recording a time of arrival (Tarrival-kd) at the at least one other known device; repeatedly broadcasting and receiving messages and recording associated times of arrival at the at least one other known device; and applying a fit curve to the recorded arrival times to estimate a time of an event. Related devices and systems are also provided.
