In august, a conference of astronomers stripped pluto of its status as a planet, but nasa is still sending a probe to pluto. it arrives in 2015
接著，回到未來。 nasa在2006年帶著三個重要的擴展國際空間站的航天飛機任務重返太空。行星探測器，仔細對火星進行了探測，發現了最近有水流的跡象。With these data, in terms of ship maneuverability, response equation of ship movement, wind and current math model, the paper carries out ship navigation track simulating and various parameter calculations. the paper is made up by the sixth chapter
有了這些數據之後，根據船舶的操縱性能和船舶運動響應方程以及風、流的數學模型，來進行船舶的航跡模擬和船舶在橋區航行時的各種參數計算。Observation of meteors throws light on our understanding of the motion of the celestial bodies in our solar system, physical properties of the earths upper atmosphere and the spatial distribution of meteoroids which helps choosing safe and proper trajectories for launch vehicles such as artificial satellites
觀測研究流星對研究太陽系天體的運動地球高空大氣物理性質了解流星體分佈這項資料對選擇航天器如人造衛星的運行軌跡十分重要等都有重要的意義。The chapter 3 and 4 are the core of this dissertation. under the theory of ship manoeuvre capability, it calculates the moving track and strap especially affected by wind and current. base on the analysis of those parameter, the basic theory is provided on navigational safety in the bridge waters
以試驗及調研的數據為依據，運用第三章建立的數學模型分析、計算船舶在橋區運動的軌跡及航跡帶，重點計算在風、流等因素影響下的船舶橫向漂移量，並對船舶在橋區運動軌跡方程的參數及橋區影響船舶橫向漂移量的因素進行分析，為船舶在橋區安全航行提供理論依據。Then the traditional pd controller and gain - scheduling fuzzy pd controller were designed to realize path following of parafoil system. simultaneously, several control strategies were brought forward in view of the basic flight properties of parafoil system. the important one was described as following : the
同時，基於翼傘系統基本運動特性，提出了一系列有針對性的控制策略，其中重要的一條是，將平均風的影響在軌跡歸航中修正，而大氣紊流的影響作為干擾由控制器來補償。First, the range - velocity transformation and the target detection are finished, and estimate the range, velocity and azimuth of the detected targets for target tracking
故必須先依據高頻雷達信號處理流程完成對二維距離?速度譜變換以及對目標的檢測、參量估值和航跡建立。分享友人
