A portable ship integrated navigation system and navigation method

Abstract

The invention relates to a portable ship integrated navigation system and navigation method, and belongs to the technical field of navigation. The portable ship integrated navigation system with the advantages of small size, light weight, low power consumption and simplicity in operation is realized by highly integrating an inertial navigation sensor, a satellite navigation sensor and a celestial navigation sensor on the basis of an electronic sea chart display module through integral design in order to overcome the shortages of present ship integrated navigation systems. The portable ship integrated navigation system comprises a combined navigation subsystem, an electronic sea chart subsystem, a display control unit and a power supply module. Compared with the prior art, the method allows a heavenly body height needed by celestial navigation calculation to be directly acquired from an attitude heading reference module through function reuse; and compared with existing schemes, the method realizes integration of the ship integrated navigation system through only arranging a monocular and a needed fixing device on hardware without a set of heavenly body height measuring device.

Description

technical field [0001] The invention relates to a portable ship comprehensive navigation system and a navigation method, belonging to the technical field of navigation. Background technique [0002] The ship navigation system is used to guide the ship to reach the destination accurately, efficiently and safely from the starting point, and plays a very important role in the process of ship navigation. With the development of science and technology, there are more and more types of ship navigation systems, common ones include inertial navigation system, satellite navigation system, log, ship automatic identification system, digital navigation radar and electronic chart display information system (ECDIS ), etc. These navigation systems have different working principles and different functions. The comprehensive ship navigation system realizes the physical connection and information integration of the above-mentioned various navigation systems through network technology and inf...

AI Technical Summary

Problems solved by technology

[0003] The volume, weight and power consumption of the existing ship integrated navigation system are relatively large, and the price is quite expensive, which brings some problems, including: first, it is difficult to install and use on ships with smaller tonnage; Second, when the crew leaves the ship to perform tasks or emergency use, the existing ship integrated navigation system does not meet the needs of portability; third, the existing ship integrated navigation system adopts fixed installation, and the coupling with the ship is relatively strong. When a fire or power failure occurs on a ship, it is easy to cause the integrated navigation system to fail

At present, there is no report on the portable ship integrated navigation system
