Simplified models of an accelerometer and a gyro were examined with the aid of simulation. The method for computation of direction cosine and the accumulation of velocity increments are discussed to derive an efficient configuration of navigation. Digital simulation of navigation including gyro and accelerometer dynamics was conducted to search the optimal cycle of computation and to evaluate the effects of error factors. The accuracy of the velocity has proved to depend mainly on the output cycle of the sensors, and the accuracy of position on the integration cycle of the velocity. The scale factor error and bias of the accelerometer are the most significant terms to be compensated. The characteristics of coning drift have been fully investigated by simulation, but an effective method of correction remains to be studied. This study will be extended to examine closed loop simulation which includes guidance, steering and dynamics of vehicle.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0416000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-416","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所宇宙研究グループ"},{"subitem_text_value":"航空宇宙技術研究所宇宙研究グループ"},{"subitem_text_value":"航空宇宙技術研究所宇宙研究グループ"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Space Technology Research Group, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Space Technology Research Group, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Space Technology Research Group, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森, 英彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"新田, 慶治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大坪, 孔治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MORI, Hidehiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NITTA, Keiji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OTSUBO, Koji","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-29"}],"displaytype":"detail","filename":"naltr00416.pdf","filesize":[{"value":"3.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00416.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44665/files/naltr00416.pdf"},"version_id":"313b0ac8-c162-4497-b726-ceed0eb64a58"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"ストラップダウン方式を用いた慣性誘導システム-航法計算法の評価-","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ストラップダウン方式を用いた慣性誘導システム-航法計算法の評価-"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44665","relation_version_is_last":true,"title":["ストラップダウン方式を用いた慣性誘導システム-航法計算法の評価-"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:53:01.036328+00:00"}
