Surfaced submarines entering and leaving port navigate similarly to traditional ships but with a few extra considerations because most of the boat rides below the waterline, making them hard for other vessels to see and identify. Submarines carry an inertial navigation system, which measures the boat’s motion and constantly updates position ...
Autonetics included the Navigation Systems division, designing and producing inertial and stellar-inertial navigation systems for ships, submarines, missiles, aircraft and space vehicles. One of the automatic navigation systems produced by the division was the N-6 or NAVAN (North American Vehicle Auto Navigation) for the Navaho missile system ...
Schuler tuning is a design principle for inertial navigation systems that accounts for the curvature of the Earth. An inertial navigation system, used in submarines, ships, aircraft, and other vehicles to keep track of position, determines directions with respect to three axes pointing "north", "east", and "down".
An inertial navigation system (INS; also inertial guidance system, inertial instrument) is a navigation device that uses motion sensors (accelerometers), rotation sensors and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the ...
The ability to navigate at extreme latitudes without surfacing was enabled by the technology of the North American Aviation N6A-1 Inertial Navigation System, a naval modification of the N6A used in the Navaho cruise missile; it had been installed on Nautilus and Skate after initial sea trials on USS Compass Island in 1957.

The Ship's Inertial Navigation System (SINS) was developed earlier to provide a continuous dead reckoning update of the submarine's position between position fixes via other methods, such as LORAN. This was especially important in the first few years of Polaris, because Transit was not operational until 1964. [ 19 ]
It is an inertial navigation system with an additional star-sighting system (this combination is known as astro-inertial guidance), which is used to correct small position and velocity errors that result from launch condition uncertainties due to errors in the submarine navigation system and errors that may have accumulated in the guidance ...
The submarine has an improved inertial navigation system over other vessels of the class. The boat also has the improved internal communication system—SNTI, Système Numérisé de Transmissions Intérieures (Digital Internal Communication System).
