"multipath interference, clock bias, complex multi-beam transmissions limits use for navigation, overcome combining advanced 5G signal tracking with real-time fusion of satellite/ cellular measurements... 5G synchronization/ reference signals stabilize tracking in environments affected by multipath interference, reducing ranging errors... phase-stabilized Kalman filter helps maintain accurate carrier phase estimates... continues delivering reliable positioning when satellite visibility is severely limited... autonomous vehicles"
