ROTATION BASED ALIGNMENT OF A GROUP OF WIRELESS TAGS
First Claim
1. A method for determining a location of a wireless tag, the method comprising:
- generating or receiving, by a tagged mobile device, an estimated location of another tag that communicates with the tagged mobile device;
receiving or generating, by the tagged mobile device, multiple distance measurements that are obtained during different points of time;
wherein the multiple distance measurements are obtained during a rotational movement of the tagged mobile device and represent distances between the tagged mobile device and the other tag;
finding a certain angle of rotation of the mobile device that corresponds to a minimal distance measurement of the multiple distance measurements; and
amending the estimated location of the other tag based upon the certain angle of rotation.
