Integrated positioning device and method for water surface carrier

The invention discloses a comprehensive positioning device for waterborne carrier and a method thereof. The comprehensive positioning device for waterborne carrier comprises a multi-path GPS signal receiving module for converting received GPS satellite signals at several measurement points of the carrier into multi-path satellite pseudo range original data and satellite state data; a beacon signal receiving module for converting received different signals of beacon station into pseudo range differential data; a data transmission station for transmitting received differential data of mobile station to an information processing monitor module; an information processing monitor module for obtaining the positioning data of the waterborne carrier to the multi-path satellite pseudo range original data, satellite state data, pseudo differential data and mobile station differential data. The invention utilizes multipoint measurement and multi-differential source comprehensive processing technique to improve GPS positioning precision. The comprehensive positioning device can improve positioning device of large carrier significantly; has high device utilization rate; has the functions of positioning, navigation and communication; and can be used for various fields and applications in sea tests.
