Abstract
Methods and apparatus for transmitter and receiver localization within an environment. A transmitter transmits a signal that includes information (e.g., wavelength, polarization, and/or modulation) that varies based on observation angle. Receiver(s) may estimate direction of the transmitter in the environment based on the received signal. Intensity of the signal may be used to determine distance of the transmitter to the receiver(s). The receiver(s) may then convey the respective estimated distance and direction to the transmitter, for example via a wireless connection. The transmitter may then generate a map of the respective distances and directions to receiver(s) in the environment, and may convey absolute location and orientation of the transmitter in the environment to the receiver(s), for example via a wireless connection.
