Location using round trip time vectors using an airborne platform

A method and devices are disclosed for producing a RTT vector (RTV) that is based upon the change in an airborne measuring station position and the corresponding RTT results taken at known time intervals to a ground based target station. In one embodiment, the target station is an access point or st...

Zusammenfassung:	A method and devices are disclosed for producing a RTT vector (RTV) that is based upon the change in an airborne measuring station position and the corresponding RTT results taken at known time intervals to a ground based target station. In one embodiment, the target station is an access point or station conforming to the IEEE 802.11 standard and the airborne measuring station 110 may also be a device that conforms to the IEEE 802.11 standard. The disclosed method enables the location of a target station to an accuracy in the order of, for example, less than one half degree of bearing within, for example, a period in the order of 5 seconds.
