METHODS AND SYSTEMS FOR ACHIEVING VITAL ULTRA-WIDEBAND (UWB) BASED TRAIN CONTROL

摘要

Systems and methods are provided for achieving vital ultra-wideband (UWB) based train control. Train-mounted units and wayside units that incorporate at least two separate and independent radios are used to obtain independent and separate ranging measurements in trains based on communications between the train-mounted units and wayside units. The communications includes communication of ultra-wideband (UWB) based signals.
