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

Embodiment Construction

[0030] The technical key points of the present invention are: 1. Carry out integrated design to the integrated navigation subsystem and the electronic chart subsystem, realize the portability of ship integrated navigation system; The vertical axis of the accelerometer is parallel, and the height of the celestial body in the process of celestial navigation can be directly obtained from the attitude reference module; ③The monocular telescope in the celestial navigation module is installed and disassembled by guide rails, which improves the ergonomics of astronomical observation .

[0031] The following will combine Figure 1 to Figure 5 A detailed description of a portable ship integrated navigation system and navigation method provided by the present invention, which is an optional embodiment of the present invention, can be considered by those skilled in the art within the scope of not changing the spirit and content of the present invention. Revise and polish it.

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...
