NASA recently to launch tracking hurricane change small satellite group NASA released a new generation of earth observation satellite "hurricane global navigation satellite system (CYGNSS)" will be launched in December 12th the Tencent space news according to NASA’s Web site reported, at present, NASA plans to launch in December 12th the earth science small satellites, it the survey will help scientists track, and the intensity of hurricanes, storm surge forecast, drawn up in Florida, Cape Canaveral Air Force station. The hurricane global navigation satellite system (CYGNSS) will be able to understand some of the unknown information prior to the survey, so as to better understand the formation and intensity of tropical cyclones and hurricanes. Deputy director of NASA’s Science Mission Directorate Thomas Zuerbu Morrison (Thomas Zurbuchen) said: "this is the first hurricane earth reconnaissance missions, 8 satellites as a group, CYGNSS will complete the single detector unable to complete the task, it is capable of high time resolution of internal surface wind speed measurement of hurricanes and tropical cyclones, which have help us to better understand and predict the deadly storm is formed." The CYGNSS mission will better weather forecast, accurate measurement of wind speed and the storm surge is GPS road navigation technology based on the surface, CYGNSS will use 8 small satellites to measure the earth’s ocean roughness, mission scientists will use the data to calculate the sea surface wind speed, as well as analysis of the intensity of the storm. Different from the existing meteorological satellite, CYGNSS can penetrate the storm eye wall (that is, the strongest wind speed) of the storm, access to important data on the strong core of the storm. The hurricane’s eye is a dense ring structure of a thunderstorm cloud that surrounds a calm hurricane eye. The inner core region is like a storm engine, which extracts energy from the warm surface of the water and evaporates into the earth’s atmosphere. CYGNSS small satellite system will continue to monitor the global tropical storm with wind surface latitude ocean, each satellite can 4 times per second wind measurement for satellites, can be 32 times per second wind measurement. The satellite system is the first complete orbit mission NASA Earth project selection risk, the risk of the earth program focused on scientific survey of low cost, fast, will help us to improve the understanding of the current complex and dynamic earth climate system, to ensure the continuous improvement of future climate change prediction.
