RESEARCH ON CRASH ICEBREAKING PATTERN RECOGNITION OF XUE LONG FROM GPS DATA
摘要
Abstract
TheXUE LONG is the only icebreaker currently deployed in Chinese polar research. The icebreaking status is an important feature of vessels sailing in polar regions. Based on GPS data of theXUE LONG, we designed an algorithm to recognize its crash icebreaking status. In the analysis of data obtained during the entirety of the Chinese 28th Antarctic Expedition, the recognition rate was >86.1% and the accuracy of rec-ognition was >98.0%. Using the developed algorithm to analyze the data obtained during the Chinese 27th Antarctic Expedition produced a recognition rate of 85.0%, and accuracy of recognition up to 93.5%. The GPS data of these two voyages verified the applicability of the algorithm, and the differences between the statistical results showed the different icebreaking states.关键词
