簡介：中國民航學院碩十學位論文摘要GPSINS是目前廣泛應用于航空、航海、航天中的組合導航系統。針一對GPSINS在民用航空中的應用，本文進行了SINSGPS組合導航系統的設計與仿真。文中利用在BOEING737300模擬機上的實驗研究數抓，對BOEING了37飛機的慣性導航系統進行了分析和仿真研究。根據國際民航組織新ILIL行系統的實施計劃，我國目前正在進行由路基導航系統向星基導航系統轉換的論證，本文結合相關課題，研究GPS在我國民用航空中的可用性。從導航的可用性和連續(xù)性等性能考慮，采用GPS與慣導組合的方式。本文同時討論了GPS工NS組合導航系統的設計和仿真。在BOEING了37300模擬機數據的基礎上，采用松散組合方式，用H濾波方法對組合系統進行了仿真在飛行的不同階段，為消除GPS信號不好造成的影響，采用了星際增強系統SBAS提高組合導航系統的精度、連續(xù)性、可用性和安全性。仿真結果證明得到的組合導航系統的J性能較為滿意。論文的研究成果對GPS工NS組合導航系統在民用航空中的實際應用有一定的參考價值。關鍵詞慣性導航系統INS，全球定位系統GPS，組合導航，HM濾波中國民用航空學院學位論文獨創(chuàng)性聲明本人聲明所呈交的學位論文是我個人在導師指導下進行的研究工作及取得的研究成果。盡我所知，除了文中特別加以標注和致謝的地方外，淪文中不包含其他人己經發(fā)表或撰寫過的研究成果，也不包含為獲得中國民用航空學院或其它教育機構的學位或證書而使用過的材料。與我一同工作的同志對本研究所做的任何貢獻均己在論文中作了明確的說明并表示了謝意。研究生簽名辮一日期44Z6中國民用航空學院學位論文使用授權聲明中國民用航空學院、中國科學技術信息研究所、國家圖書館有權保留本人所送交學位論文的復印件和電子文檔，可以采用影印、縮印或其他復制手段保存論文。木人電子文檔的內容和紙質論文的內容相一致。除在保密期內的保密論文外，允許論文被查閱和借閱，可以公布包括刊登論文的全部或部分內容。論文的公布包括刊登授權中國民用航空學院研究生部辦理。研究生簽名叢早一FY9FI簽名期YAOQ對
