To solve the guidance error caused by inaccurately initial position of rapid launch in inertial navigation, a navigation method using a single satellite sensor to observe the near Earth communication satellite is proposed, which can correct the posit

The Intercept Method (originally known as the Intercept Azimuth method) was created in 1875 by the French captain (latter admiral) Marq de Saint Hilaire. The method is still used today and is accepted by the International Maritime Organization as an

As ships and maritime transport have evolved, knowledge of navigation methods has also evolved, reaching today modern means that require less of the skills and time of navigators to determine the position of the ship on sees and oceans. However, the

Satellite navigation over recent decades has become the default and, in some cases, sole source of positioning for maritime vessels. The classic sextant has been all but forgotten by a significant number of ship navigators. However, recent risks to R
