Abstract

Underwater navigational systems and methods utilizing sunlight polarized via scattering through the water column that does not require an underwater vehicle to surface or use a global position system to maintain precise navigational positions and headings. These navigational systems and methods may be employed by manned or unmanned underwater vehicles and may be utilized by individual units and by units operating in a swarm.
