Abstract
Systems and methods for a high-precision time of arrival ultra-wideband positioning system are provided. In one embodiment, a method for generating precision localizer messages for an ultra-wideband time-of-arrival positioning system is provided. The method comprises receiving a signal from an atomically accurate reference, generating a timing signal based on the atomically accurate reference signal, correcting a system time based on the timing signal when an error is detected, and transmitting an ultra-wideband signal having a localization message based on the system time.
