Abstract

The invention relates to a ship comprehensive PNT (position, navigation and timing) system based on adaptive information fusion, which is characterized by comprising a PNT sensor unit, a data acquisition unit, an information fusion unit and a chart navigation unit; the PNT sensor unit is connected with the data acquisition unit for acquiring ship position, navigation and timing PNT information; the data acquisition unit is connected with the information fusion unit for integrating the acquired ship PNT information and outputting the information to the information fusion unit; the information fusion unit is connected with the chart navigation unit for preprocessing of sensor raw data, multi-schema switching adaptive fusion, fault detection, fault isolation and system reconstruction; and thechart navigation unit is used for implementing ship driving assistance of ship positioning navigation, route planning and navigation monitoring, etc. The system in the invention can provide high-precision and robust PNT information and other navigation aid information, thereby meeting the ship navigation requirements and improving the ship navigation safety.

Description

technical field [0001] The invention belongs to the technical field of ship navigation, and relates to a ship comprehensive PNT system, in particular to a ship comprehensive PNT system based on adaptive information fusion and a monitoring method thereof. Background technique [0002] With the increasing frequency of global economic and trade exchanges, the increasing density of ship traffic, more and more malicious and unintentional interference of electromagnetic frequencies, coupled with other environmental challenges (low visibility, ionospheric scintillation) and problems caused by geographical factors, The traffic environment is becoming more and more complex, and collision avoidance and grounding accidents occur frequently. The demand for high-precision PNT information is increasing day by day during ship navigation. However, the ship positioning, navigation and timing (PNT, Position, Navigation and Timing) information in the existing system presents inaccuracy and inc...
