It becomes the optimum estimation in the sense that it gives the minimum variance and most likelihood estimator on the following conditions: The system and observation mechanism is represented by linear equations. The corresponding noise follows the normal distribution whose parameters are known beforehand, and used properly in the estimation. As a matter of course, this can be applied to trajectory estimation of the space vehicle with slight modification, and validity of the method for such purposes has been widely assured. Therefore, in order to estimate the most probable powered flight trajectories of sounding rockets launched at KSC from all the available imformation about the system state, Kalman filters are applied and formulated with necessary approximations and modifications. The system is linearized by applying the purturbation around the nominal trajectory and nine state variables are selected taking the properties of the system and quality of the available data into considerations. This filter was used to evaluate the newly adopted attitude reference system of L-4SC-3 rocket launched in September, 1974. The results are shown in this paper and they correspond well with that of telemetry data or a priori information about the system. If these telemetry data about the attitude or accerelation of the vehicle are provided instantaneously at the launching site in addition to the tracking radar data, the same filter can be applied to the real time trajectory estimation. As this filter also can be effectively utilized for off-1ine parameter estimation with iterative computation, we are now extending it to the optimum smoother.", "subitem_description_type": "Other"}]}, "item_9_description_32": {"attribute_name": "資料番号", "attribute_value_mlt": [{"subitem_description": "資料番号: SA0124534000", "subitem_description_type": "Other"}]}, "item_9_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "東京大学宇宙航空研究所"}]}, "item_9_source_id_21": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0563-8100", "subitem_source_identifier_type": "ISSN"}]}, "item_9_source_id_24": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00161914", "subitem_source_identifier_type": "NCID"}]}, "item_9_text_34": {"attribute_name": "メタデータ提供者", "attribute_value_mlt": [{"subitem_text_value": "メタデータ提供者: ISASNII"}]}, "item_9_text_35": {"attribute_name": "JAXAカテゴリ", "attribute_value_mlt": [{"subitem_text_value": "JAXAカテゴリ: 宇宙科学研究所"}]}, "item_9_text_43": {"attribute_name": "DSpaceコレクション番号", "attribute_value_mlt": [{"subitem_text_value": "DSpaceコレクション番号: 6"}]}, "item_9_text_6": {"attribute_name": "著者所属", "attribute_value_mlt": [{"subitem_text_value": "東京大学宇宙航空研究所"}, {"subitem_text_value": "東京大学宇宙航空研究所"}, {"subitem_text_value": "東京大学宇宙航空研究所"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "石谷, 久"}], "nameIdentifiers": [{"nameIdentifier": "405063", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "馬場, 康子"}], "nameIdentifiers": [{"nameIdentifier": "405064", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "飯田, 幸栄"}], "nameIdentifiers": [{"nameIdentifier": "405065", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "ISHITANI, Hisashi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "405066", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "BABA, Yasuko", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "405067", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "IIDA, Sachie", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "405068", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2020-01-23"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "SA0124534.pdf", "filesize": [{"value": "583.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 583900.0, "url": {"label": "SA0124534.pdf", "url": "https://jaxa.repo.nii.ac.jp/record/31586/files/SA0124534.pdf"}, "version_id": "660b9aa3-8bbc-4f10-a523-aa7001a96de1"}]}, "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "KalmanフィルタによるL-4SC-3号機の推力飛しょう中のパラメータ推定について", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "KalmanフィルタによるL-4SC-3号機の推力飛しょう中のパラメータ推定について"}]}, "item_type_id": "9", "owner": "1", "path": ["1890", "1910"], "permalink_uri": "https://jaxa.repo.nii.ac.jp/records/31586", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-03-26"}, "publish_date": "2015-03-26", "publish_status": "0", "recid": "31586", "relation": {}, "relation_version_is_last": true, "title": ["KalmanフィルタによるL-4SC-3号機の推力飛しょう中のパラメータ推定について"], "weko_shared_id": -1}
