Systems and methods for wireless atomic clock synchronization using ultra wideband (UWB) pulse trains

A system for maintaining clock synchronization, the system comprising:

• an ultra-wideband (UWB) transmitting system including:
• a high precision input clock that produces a high precision clock frequency;
• a UWB transmitter that receives the high precision clock frequency and sends a message using a transmit antenna associated with the UWB transmitter, the message including a transmit time of the message in UWB transmitter clock units;
• a processor in communication with the UWB transmitter;
• and
• a counter that precisely controls transmit times of message sent from the UWB transmitter;
• and
• a UWB receiving system including:
• a UWB receiver that receives the message using a receive antenna associated with the UWB receiver from the UWB transmitter, the message being received at an arrival time in UWB receiver clock units;
• a low precision resonator that provides the arrival time in receiver clock units;
• a processor that calculates an oscillator adjustment for the low precision resonator based on the transmit time in the message and the arrival time;
• and
• wherein the processor of the UWB receiving system further 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.
