Abstract:

The wind sensors installed on the ship’s mast can measure the relative wind directly when voyaging. However, only by using the vector algorithm combined with the ship’s speed and heading can we calculate the true wind. Through quantitative analysis of the influence of the wind sensor’s zero installation error on true wind calculation, the error transfer model of the wind sensor’s direction resolution and zero installation error was established in this paper. Analysis
shows that the wind sensor’s zero installation accuracy has important influence on the true wind calculating results, in some cases it can be up to an error of 30%. In order to improve the accuracy of the true wind calculating, we must strictly control the zero installation precision of the sensor.

Key words: wind sensor, the true wind calculating, error analysis, zero installation accuracy
