Preliminary analysis on the application of geomagnetic field matching in underwater vehicle navigation;

According to the fact that the relative navigation of underwater vehicle and buoy is mainly relied on acoustical transmission,two methods of relative navigation,which are independent of acoustics are put forward.

In order to debug and verify this underwater navigation system,the simulation platform of navigation system for underwater vehicle is developed.

System testing plan and simulation of the load hung outside the underwater vehicle;

This paper introduces a new type of spinning underwater vehicle with detailed il-lustration of its system structure and working principles and offers the design of a fuzzy con-troller.

Aiming at the uncertainty of electronic compass misalignment angle on underwater vehicle-based navigation system and the difference of geomagnetic declination among different areas,a new method was proposed to compensate the course error.

The submarine launched missile must be transported by an underwater carrier.
