Weighted fusion processing method, system and product for multi-source position information

The invention relates to the technical field of ship navigation, and particularly discloses a multi-source position information weighted fusion processing method, system and product, and the method comprises the steps: obtaining a plurality of position information sources; carrying out latitude and longitude difference out-of-tolerance detection to obtain an effective position information source; if the artificial weight is set, performing weighted fusion on the effective position information source according to the artificial weight, and calculating to obtain a fusion position result; if the artificial weight is not set, calculating a performance weight, performing weighted fusion on the effective position information source according to the performance weight, and calculating to obtain a fusion position result; and outputting the fusion position result. According to the method, real-time fault diagnosis and fault information source isolation are carried out on the multi-source position information, and perf
