1. An aerial vehicle with automatic navigation comprising:
one or more DNV sensors spaced apart from each other and each configured to detect magnetic fields generated by stationary infrastructure, such one or more DNV sensors determining a magnetic vector based on the magnetic fields, such infrastructure spaced apart from the one or more DNV sensors and providing a magnetic signature that is capable of being mapped based on its characteristics and correlated to sensed magnetic vectors; one or more electronic processors configured to receive the magnetic vector of the magnetic field and determine a presence of infrastructure based upon the magnetic vector; and a navigation control configured to automatically navigate the aerial vehicle based upon the infrastructure and its weak magnetic fields detected and determined as magnetic vectors.
