Disclosed is a sensor enabled object. Beacons may be placed at fixed locations within an environment. The movement of the sensor enabled object can be tracked throughout the environment by analyzing received signals. The relative distances from the known positions of the beacons can be used in order to orient the sensor enabled object within the environment. Alternatively, the sensor enabled objects can be used to determine the relative positions of mobile objects by measuring the respective distances from each other and correlating the relationships.

An auxiliary apparatus for a lighthouse positioning system is provided. The lighthouse positioning system includes a first positioning base station and a second positioning base station, wherein the first positioning base station includes a first signal transmitter and a second signal transmitter and the second positioning base station includes a first signal transmitter and a second signal transmitter. The auxiliary apparatus calculates a first signal time sequence of the first signal transmitters, calculates a second signal time sequence of the second signal transmitters, and determines a third signal time sequence according to the first signal time sequence and the second signal time sequence. The third signal time sequence is not overlapped with the first signal time sequence and the second signal time sequence. The auxiliary apparatus transmits a plurality of signals according to the third signal time sequence.

A method of receiving EM field magnitude values indicative of a first pose of a mobile unit in relation to a base unit, receiving sensor data from a second sensor associated with the mobile unit, where the sensor data is indicative of a direction of movement of the mobile unit, calculating a set of candidate pose solutions based on the EM field magnitude values, selecting a pose from the set of candidate pose solutions based on the sensor data from the second sensor, and sending the pose to the processor.

Autonomous vehicles may communicate with each other to avoid hazards, mitigate collisions, and facilitate the flow of traffic. To enhance such cooperation, it would be highly advantageous if each vehicle were able to determine which vehicle in view corresponds to each communication message, which is generally unknown if a plurality of vehicles are in range. Systems and methods provided herein can enable autonomous vehicles to determine the spatial location of each proximate vehicle by detecting a pulsed localization signal emitted by each of the other vehicles. In addition, each vehicle can transmit a self-identifying code, synchronous with the emitted localization signal, so that other vehicles can associate the proper code with each vehicle. After such localization and identification, the vehicles can then cooperate more effectively in mitigating potential collisions.
