Abstract

The invention discloses a GNSS (Global Navigation Satellite System)-based offshore platform fine in-place auxiliary system and a working method, belongs to the technical field of GNSS marine application, and solves the problem of low automation degree of platform position acquisition in the in-place working process of an offshore platform. The system is composed of an underwater terrain acquisition end, a tugboat and offshore platform positioning end, a data fusion processing end and an application end. The underwater topography acquisition end takes a ship as a carrier, carries a GNSS and an underwater measurement sensor, and acquires submarine topography data with position information; the tugboat and offshore platform positioning end obtains the position and attitude information of a carrier in real time in a differential positioning mode by installing a plurality of GNSS receivers on a tugboat and a platform. The data fusion processing end performs secondary processing by fusing submarine topography data and positioning results of the tugboat and the platform, and generates electronic map data for assisting tugboat operation; and the application end decodes and draws an electronic map to assist in fine positioning of the offshore platform.

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...
