Abstract
A system to determine position and/or heading may include a receiver including at least two antennas configured to be coupled to the vehicle and receive electromagnetic signals including at least one of microwaves or radio waves. The system may also include a navigation module configured to determine first and second locations associated with respective first and second transmitters that send respective first and second signals. The navigation module may also be configured to determine, based at least in part on the first signals, a first relative orientation of the receiver relative to the first transmitter, and determine, based at least in part on the second signals, a second relative orientation of the receiver relative to the second transmitter. The navigation module may also be configured to determine a position and/or heading of the vehicle based at least in part on the first and second relative orientations of the receiver.
