  3. 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,所以本文自設計了這樣一個系統;還討了捷聯慣性導航系統中捷聯解算的方法,並進了模擬研究,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及其座模擬的設計思想和方案,與以往gps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gps及其座模擬,這樣的設計方法對從事衛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了驗證。
  4. First, the structure of the second generation ctdrs isl was discussed in this paper, the characteristic of coverage in the second generation ctdrs by the characteristic of orbit and the simulation model of isl was analyzed then the effect of the isl establishing process analyzed. second, the discussing and analyzing focus on the characteristic of signal during the establishing isl process, establishing the orbit model, the technology of doppler frequency shift capturing and tracking sequence and the effect of background noise, then the theory analyzing the parameters we have just mentioned, and this will support the reference for the implement of project. the simulation and test of the isl of ctdrs and analyzing from theoretical basis to implement of simulation were mainly focused in this paper
