  • Time synchronization via over-determined measurements
    Patent number: 9377524
    Abstract: Disclosed are a method and a system for clock synchronization estimation using position over-determination principles applied to TDOA measurements of well-tracked targets with a height of about 5 km and higher. Clock correction factors or delays can then be applied to sensor clock signals, providing accurate tracking of targets such as aircraft, even in the event of GPS failure or jamming.
