Because it ’ s hard to get radiation - harden hardware overseas, so the software fault tolerance techniques are significant for our national space enterprise. the computer platform of 863 plan project ” micro intelligent free - flying space robotic system ” consists of cots component. the orbit and the radiation environment of the robot are similar to ones of the argos satellite, and the system is required to have high reliability. therefore it ’ s necessary to applied the software fault tolerance techniques into the system to improve the anti - radiation capability after the techniques been verified valid
因為我國很難從國外獲得輻射加固的硬體,所以,這項軟體容錯技術對我國航天事業的發展具有較大意義。 863計劃項目「小型智能飛行機器人系統」所用的計算機平臺採用商用器件,其衛星的運行軌道與argos衛星軌道近似,面臨的輻射環境與argos衛星相似,要求具有高可靠性。因此,小型智能飛行機器人系統有必要在驗證sihft技術有效的基礎上,應用軟體容錯技術,提高其空間抗輻射能力。For example, if there is a planet orbiting around the neutron star, it will wobble a little and the pulses will come a little early or late. we can then deduce the mass and the radius of the orbit of the planet from the arrival time of the pulses. this is how the first extrasolar planet is discovered
例如假若有一顆行星圍繞一顆中子星運行,它會令中子星出現搖動,引致脈沖的間隔變長或短,由此我們根據脈沖周期的變化,可推斷出行星的質量和軌道半徑,這亦是天文學家找出第一顆地外行星時所用的方法。Mars and jupiter are the closest in of the superior planets
火星和木星是最靠近地球軌道外側的行星。The leonid shower occurs each november, when the earth ' s orbit takes it through the trail of particles shed by the comet tempel - tuttle as it swings around the sun once every 33 years
當地球穿過"坦佩爾-塔特爾"彗星尾部稠密的彗星碎片帶時,就會出現流星雨現象。這顆彗星在太陽系外圍軌道運行,它的運行周期是33年。Thirdly, an ideal satellite orbit is simulated, and on this foundation, we establish some typical simulation and testing circumstances. lastly, after simulation in the simulation and testing circumstances, we compare the performance of ukf and ekf. and then, based on the outdoor experiment of the vehicle, an analysis and contrast between our simulation results and commercial data process software is carried out, and the conclusion is obtained
首先在第三章提出的目標運動模型的基礎上建立了系統狀態方程;其次簡要分析了衛星導航系統中的各類誤差,建立了基於偽距觀測量的系統觀測模型;第四節利用yuma格式歷書數據模擬了未受攝動影響的衛星軌道,並在此基礎上建立了幾種典型的動態模擬測試環境;第五節為模擬分析和比較,先對ukf演算法和ekf演算法在動態模擬測試環境中進行了模擬比較,然後針對外場試驗,對非線性濾波獲得的定位結果與商業軟體進行了分析比較,並得出結論。Some asteroids, despite their small size, possess satellites of their own. a handful of others suffer serious perturbations by major planets and travel in highly eccentric orbits, which can send them well beyond the orbit of jupiter. the so - called near - earth asteroids cross the earth s orbit and make occasional close calls to our home planet
有些小行星體積雖小,但竟然擁有衛星而有些小行星,由於受到其他大行星的強烈攝動,軌道為極狹長的橢圓,遠日點甚至延伸至木星的軌道以外近地小行星則會越過地球的軌道,不時在我們的庭園掠過,偷窺地球的一切,若有天真的登門造訪旄轟!Extreme ultraviolet radiation and x - ray created by magnetic field around the sunspots also cause the earth s atmosphere to heat up and expand. this will create additional drag to satellites or space shuttles orbiting at low altitudes and eventually pull them out of orbits earlier than expected
太陽黑子附近的磁場所產生的遠紫外輻射和x射線,使地球大氣溫度上升並且膨脹,這對在較低軌道運行的人造衛星或太空梭帶來阻力,令它們比預期提早偏離軌道。Through the approximate handling of geomagnetic intensity and differential riccati equation, the magnetic attitude h control law of the microsatellite in a circle orbit which has external disturb and the structural perturbation is presented
通過對衛星地磁場和微分riccati方程進行近似處理,給出有外界擾動和結構化攝動圓軌道衛星系統的h _磁姿態控制規律。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。Just as mercury has a much shorter year than earth ? a mere 88 days ? the material in the inner parts of a disk invariably takes less time to complete one orbit than does material in the outer parts
正如同水星繞日周期(只有88天)較地球短,在圓盤內側的物質繞行軌道一圈所需的時間,永遠比外側的物質短。His conceptions seemed naive to her, though she was often fired by his daring flights of comprehension, whose orbit - path was so wide among the stars that she could not follow and could only sit and thrill to the impact of unguessed power
在她眼裡他的看法似乎太天真,盡管自己也常因他一套套大膽的理解而激動。他的運行軌道遠在星河之間,是她無法跟隨的。她只能為他那出人意外的沖撞所震撼。Astronomers have since detected more than 200 exoplanets, and such quirks are no longer novel : in their positioning or in some other respect, most differ substantially from the planets of the solar system
此後,天文學家們先後又發現了200多顆系外行星,而且在這些行星中,上述奇觀也不再新鮮:就軌道的位置或其他方面來看,大多數行星同太陽系的行星存在根本的差異。When pluto is near the sun, it has a thin atmosphere, but when pluto travels to the outer regions of its orbit, the atmosphere freezes and collapses to the planet ' s surface

最後,正如勞倫斯?瑪舍爾在《行星勘探卜書中所說,一個搜尋恆星光譜周期變化的聰明計劃證實在太陽系之外有無數個大行星圍繞著恆星在做軌道運行。分享友人
