Problems solved by technology

However, GPS positioning needs to meet certain vision and weather requirements, and there are often problems such as inability to search for satellites, large positioning errors, and long time. At the same time, the indoor environment in the cabin cannot be positioned in real time.
Most inertial navigation devices need to be calibrated, and long-term positioning will cause large errors
Moreover, GPS equipment or inertial navigation devices need to be continuously performed in real time, which consumes a lot of energy and takes a long time

Embodiment Construction

[0036] The concrete implementation of the present invention is described in detail below, it is necessary to point out here that the following implementation is only used for further description of the present invention, and can not be interpreted as limiting the protection scope of the present invention. Some non-essential improvements and adjustments still belong to the protection scope of the present invention.

[0037] The invention provides a positioning system for a cruise ship at sea, as attached Figure 1-4 As shown, it includes a GPS device 1 (marked as point G) arranged on the top of the cruise ship, and also includes a calibration device 4 whose vertical distance from the GPS device 1 is L. When the GPS positioning condition is met, that is, when the number of visible satellites is at least 4, the GPS device 1 receives satellite data from the satellites, obtains its own coordinates G(x, y, z) after calculation by the control processor. The location of the calibrati...

Abstract

A marine cruise ship positioning system and method thereof are disclosed. The system comprises a GPS device disposed at the top of a cruise ship, a calibration device disposed at a vertical distance Lfrom the GPS device, a plurality of anchor points respectively disposed on the deck of the cruise ship and in a ship cabin, a first transceiver device disposed at the stern of the cruise ship, a second transceiver device disposed on the bow of the cruise ship, an inertial navigation device and a control processor. The GPS device, the calibration device, the plurality of anchor points, the inertial navigation device, the first transceiver device and the second transceiver device are connected with the control processor separately. Real-time positioning in the cruise ship and the cruise ship cabin can be realized, the calibration and update can be performed in real time, the positioning accuracy can be improved, the seamless positioning can be realized, the applicability is strong, and theenergy consumption is low. The shortcomings of large compensation calibration error of the inertial navigation device are made up.

Description

technical field [0001] The invention relates to the field of wireless satellite positioning, in particular to a marine cruise positioning system and a method thereof. Background technique [0002] At present, with the vigorous development of marine and sea tourism business, it is necessary to pay attention to promoting the coordinated development of cruise transportation, land transportation, air transportation and other transportation methods, and continuously improve the technological content and innovation of ports and ships. By the end of 2020, the number of global cruise tourists is expected to exceed 30 million. With the increase in demand, investment in the cruise industry in various countries has also continued to increase, and the overall supply level of the cruise industry measured by carrying capacity has also continued to increase. [0003] The supporting facilities of the cruise ship is a huge comprehensive supporting facility, which includes the supporting faci...
