The First "Straits Cup" yacht race opened on July 30,2009 in Xiamen.15 yachts with 154 crew members across " Straits" sailed from Xiamen Bay along the route through which Zheng Chenggong recovered Taiwan in those years. It’s the first time for mainland yachts to go across Taiwan Strait.
Because July, August are high period of typhoon, unpredictable and complicated marine environment, busy sea channels in Taiwan Strait, frequent shuttling of large ships. To this end, commissioned by the Organizing Committee, Tianjin 712 Communication and Broadcasting Co., Ltd. installed AIS Automatic Identification System equipment for all participating yachts. As a new type of smart-aided navigation equipment, this product automatically sends names of yacht and location information to other vessels while helping crew to achieve navigation. The crew can also know the situation and position of other yachts through the chart display terminals to achieve information sharing between yachts. All these functions can ensure the safety of every participating yachts to maximum extent.
It’s the first time for AIS Automatic Identification System to be used in domestic Regatta.So before the race, this product had attracted a number of domestic medias’ attention, including CCTV. And all the medias actively issued reports on this product. CCTV’s "News 30 minutes" column reported that "AIS Automatic Identification system is a high-tech marine communication product. In the past, such kind of product were only used and installed in foreign luxury yachts. With the development of China’s technical level, domestic enterprises have been able to independently develop and produce the same quality products which in accordance with international standards, this will surely contribute to China’s marine industry."
