The algorithm of strapdown inertial navigation system is also discussed and then use the flight - track generator to give a simulation, since a closed loop feedback integrated navigation system is designed in this paper, and the output of the filter must feed back to the strapdown inertial navigation system, the analysis of the algorithm in strapdown inertial navigation system is important. the scheme to design the trajectory of gps and the simulation of gps constellation are then studied, the simulation of gps constellation is given from the calculation of vernal equinox base on the principle of celestial mechanics, this method of different from other methods given by other paper and is useful to the research of satellite navigation system. a new method to abstract noise modal in integrated navigation system is proved to be useful in practice, this method, which is given by use the principles of stochastic processes, statistics, time series analysis, and system identification, is suitable for the kalman filter in integrated navigation system
如航跡產生器的設計，該航跡產生器是研究組合導航問題的前提，從國外一些研究組合導航系統的文獻中可以看出，設計這樣一個航跡產生器是非常必要的，所以本文自行設計了這樣一個系統；還討論了捷聯慣性導航系統中捷聯解算的方法，並進行了模擬研究，由於在本文設計的閉環反饋式組合導航系統中，對捷聯慣導系統的平臺誤差進行閉環控制，需要將濾波器輸出的校正量反饋到捷聯解算內部，所以必須對捷聯解算進行深入的研究和分析，更何況捷聯解算問題本身也是導航界的一個熱門研究課題；另外，本文還介紹了gps軌道及其星座模擬的設計思想和方案，與以往gps軌道和星座模擬不同的是本文從天體力學中計算春分點開始，逐步進行gps軌道及其星座模擬，這樣的設計方法對從事衛星導航的研究工作是有價值的；還對組合導航中誤差建模方法進行了研究，綜合運用隨機過程、概率統計、時序分析及系統辯識等方面的理論提出了一套適合組合導航卡爾曼濾波的誤差建模方法，並運用實際研究工作中的測量數據對該方法進行了驗證。 -
In recent ten years, countries all over the world have launched numbers of deep space probes to explore various kinds of valuable celestial bodies in the solar system
最近的數十年中，世界各國發射了許多深空探測器，用以探測太陽系內有科學價值的各類大小天體。 -
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。 -
To be precise, we have to mention the time, for example, year 2000. 0, when we talk about the celestial coordinate system. we will not go into the details
嚴格來說，當我們使用天球座標來標示天體的位置時，應該同時指出是哪一年的座標，例如公元2000 . 0年。 -
