Methods for determining a location of an unknown device (UD) from a plurality of known devices (KDs) are provided including receiving, at the UD, periodically broadcasted messages from each of a plurality of KDs. Corresponding arrival time stamp (T) of each periodically broadcasted message from each of the plurality of KDs are recorded.

A departure time of the periodically broadcasted message from each of the plurality of KDs is known by the UD in master device time units (T). X, y and z coordinates of a location of each of the KDs is known by the UD. The x, y and z coordinates of an actual location of the UD is calculated using the x, y and z coordinates of each of the KDs, the recorded arrival times (T) of each of the periodically broadcasted messages from each of the plurality of KDs and the known departure times of each of the periodically broadcasted messages (T) from each of the plurality of KDs.

Methods for determining location of unknown devices in a synchronized network and related systems

Some embodiments of the present inventive concept provide a system for maintaining clock synchronization including an ultra-wideband (UWB) transmitting system and a UWB receiving system. The high precision input clock at the transmitting system produces a high precision clock frequency. A message is sent from the transmitting system including a transmit time of the message in UWB transmitter clock units. The message is received at the UWB receiving system at an arrival time in UWB receiver clock units. A time of flight (ToF) and an oscillator offset is calculated based on the transmit time included in the message and the arrival time. A tuning register uses the calculated oscillator adjustment to adjust the low precision resonator to synchronize the low precision resonator with the high precision input clock at the UWB transmitting system.
