Abstract

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.

Description

technical field [0001] The invention relates to the technical field of signal processing, and more specifically, the invention relates to a comprehensive positioning device and method for water surface carriers. Background technique [0002] Surface navigation and positioning can provide an initial position reference for various measurement and tracking equipment, and is an important means of measuring target position, speed, and navigation status. With the continuous improvement of system performance, there are higher requirements for comprehensive information such as the sea area of ​​the sea area, the accuracy of positioning and speed measurement, the coordinated use of equipment, and target navigation. Therefore, it is necessary to build a large-scale, high-precision, An air-to-sea compatible, highly dynamic, and cost-effective integrated differential GPS positioning system. [0003] In order to improve the positioning accuracy, the existing GPS receivers often use the ...
