Wave and sea level measuring method for deep sea and high sea based on satellite-based differential enhanced technology

Abstract

The invention discloses a wave and sea level measuring method for deep sea and high sea based on a satellite-based differential enhanced technology. By taking a Beidou system as a primary platform which is matched with a GPS (Global Positioning System), a fused localization method is formed by adopting the satellite-based differential enhanced technology, so that wave and sea level measuring work of deep sea and high sea in a global range is realized. The method comprises the following technical steps of: receiving a satellite positioning signal and a satellite-based differential signal; calculating three-dimensional position data of a satellite float; separating wave data and sea level data; calculating the wave data; calculating the sea level data; and transmitting the wave data and sea level data to a shore station data receiving system. By mounting a Beidou / GPS satellite positioning receiving card board and a satellite-based differential signal receiving module, waves and sea levels in the deep sea and high sea in the global range can be measured. The method has the characteristics of being high in measuring precision, far in working distance, wide in coverage, long in cruising duration and the like.

Description

technical field [0001] The invention relates to a method for measuring sea waves and tide levels, in particular to a method for measuring sea waves and tide levels using a Beidou system and satellite buoys. Background technique [0002] Ocean wave data and tide level data are important elements of ocean hydrological observation, mainly including wave height, wave period, wave direction and tide level. The precise measurement and forecasting of waves and tide levels in deep seas is of great significance to ocean shipping, scientific research, disaster prevention and mitigation, and national defense and military affairs. . my country has a huge demand for wave and tide level measuring instruments and equipment suitable for deep and open seas. [0003] The wave buoy is an important device for measuring wave data, and the tide gauge is an important device for measuring tide data. [0004] Wave buoys measure wave data. According to different working principles, they can be mai...

AI Technical Summary

Problems solved by technology

The former requires the cooperation of tide wells at coastal stations for measurement, while the latter is limited by the short cable length, so both have shortcomings, and neither is suitable for tide level measurement in deep and open seas

[0006] At the same time, the existing wave and tide level measurements are carried out independently, and it is impossible to jointly measure wave and tide level data. There is a problem of data fusion difficulties, which artificially separates the natural internal relationship between waves and tide levels.
