<p>Method and apparatus for determining position of a target device relative to a mobile structure are disclosed. The method includes obtaining measurements by the target device with respect to a plurality of radio beacons, determining whether the target device is on the mobile structure using the measurements, and determining location of the target device relative to the mobile structure using the measurements. The method of determining whether the target device is on the mobile structure includes at least one of comparing motion of target device with motion of mobile structure, detecting mobile radio beacon(s) on the mobile structure from the target device over a period of time, comparing velocity and location of the target device with respect to velocity and location of the mobile structure, comparing measurements obtained by target device from the plurality of radio beacons, and comparing locations obtained by target device from the plurality of radio beacons.</p> |
