Systems, apparatus and methods for cancelling a noise voltage at a vehicle are presented. An noise cancellation system (NCS) can be configured to null an earth-to-body voltage at the vehicle to prevent its interference with a receiver system. An (NCS) can include a noise sensor (NSSR) configured to sense a noise voltage, and a noise-nulling device (NNDV) configured to provide an anti-noise output. An anti-noise injector (ANI) can be configured to drive the anti-noise output at an anti-noise injection site In an example embodiment, an anti-noise output can be provided directly to the receiver system by cable. Alternatively, an anti-noise signal can be inductively or capacitively coupled to a vehicle structure or component that is not part of the receiver system. A noise cancellation system can be arranged in a feedback or feed-forward arrangement. Radio frequency noise and non-radio frequency noise can be cancelled.
