Abstract
Vehicles and methods of navigating vehicles comprise at least three receiver antennae configured to receive radio frequency (RF) signals from one or more RF-transmitting antennae coupled to an object, receiver circuitry coupled to the receiver antennae to acquire the RF signals and to determine timing information from the acquired RF signals, memory storing information related to fixed distances between each receiver antenna and each other receiver antenna, a processor configured to determine a relative position of the vehicle with respect to the one or more RF-transmitting antennae based on the stored information related to the fixed distances between each receiver antenna and each other receiver antenna and on the timing information determined by the receiver circuitry, and a control system configured to control operation of the vehicle in response to the relative position of the vehicle with respect to the one or more RF-transmitting antennae determined by the processor.
