Abstract
A method and system for determining a position and orientation of a receiver relative to a transmitter includes transmitted positioning signals having different frequency components that define a common period. One or more of the transmitted positioning signal have identifiable phase characteristics relative to the start of the common period. The positioning signals are received at the receiver. A time point corresponding to the start of the common period is determined from the received positioning signals. The polarities of the received signals can then be determined based on properties of the positioning signals relative to the start of the common period and relative to properties of the transmitted positioning signals. These polarities can be used to track a signed position and uniquely associated orientation of the receiver relative to the transmitter.
