Electro-Magnetic Direction and Ranging (EMDAR) is a passive sensor technology that detects emissions along the EM spectrum to identify and track other vessels.
The Lorentz distribution is named after Hendrik Lorentz) is a continuous probability distribution. It is also known, especially among mathematicians as the Cauchy distribution (after Augustin Cauchy).
Navigation involves management of the vessel’s movement in space, including faster-than-light travel between stellar systems and maneuvering the vessel around other vessels and objects at subluminal speeds.
