Abstract

The invention discloses a GNSS-based precise positioning auxiliary system and a working method for an offshore platform, belonging to the technical field of GNSS marine applications, and solves the problem of low degree of automation in obtaining the platform position during the offshore platform positioning process. The system consists of underwater terrain acquisition end, tugboat and offshore platform positioning end, data fusion processing end and application end. The underwater terrain acquisition end uses ships as carriers, equipped with GNSS and underwater measurement sensors, to obtain seabed terrain data with position information; the tugboat and offshore platform positioning end install multiple GNSS receivers on the tugboat and platform, through differential positioning The position and attitude information of the carrier can be obtained in real time in a real-time manner; the data fusion processing end performs secondary processing by fusing the seabed terrain data and the positioning results of the tugboat and the platform, and generates electronic map data for assisting the tugboat operation; the application end decodes and draws the electronic map , used to assist the precise positioning of offshore platforms.

Description

technical field [0001] The invention discloses a GNSS-based precise positioning auxiliary system and a working method for an offshore platform, belonging to the technical field of GNSS marine applications. Background technique [0002] The method of satellite differential positioning can obtain centimeter-level and millimeter-level positioning accuracy. Because it has greatly changed the traditional surveying industry, it has gradually replaced measuring equipment such as total stations and levels in many fields. With the exploration and development of marine resources, more and more offshore platforms have been put into use. The positioning operation of offshore platforms is a high-risk joint operation, which requires a short safety distance between platforms, which requires the positioning accuracy of offshore platforms to reach the meter level or above. At present, the platform position determination methods for precise positioning operations on offshore platforms are mo...
