A Novel Method to Estimate the Sea State for Recycling Work on the Sea Surface

The recycling of marine exploration equipment after it has surfaced is greatly affected by sea state. In order to estimate the state in real time, this paper proposes a method for measuring wave elevation, which modifies integrated results GNSS/SINS up direction virtual horizontal lines extract fluctuation information. From these information, significant heights (SWH) can be calculated as only input parameter P-M spectrum, and series height data further simulated. When GNSS interrupted due severe state, simulated with SINS deal distortion problem. simulation show that application spectrum intermittent situation obvious improvement effect important significance.
