Abstract
There is provided a subject location system, including a master processing unit, a receiver, and at least one Tag associated with the subject. The system includes a Hub with a master processing unit and the Tag includes transponders. Range and phase data are used to calculate the position of the Tag in relation to the Hub, and phase cycle errors are eliminated by, the use of a cyclical search minimizing an innovation inner product.
