觀測歷元
英文
epoch of observation-
In the stage of the sun and the moon in sight, azimuth of the sun, the earth and the moon in the spacecraft body coordinate system is simulated. combining the simulated azimuth with the ephemeris of the sun and the moon, the state equation and observation equation are modeled. the initial orbital parameters calculated by least square method are used in orbit state equation to predict spacecraft state and to realize autonomous navigation
在日月可見階段，模擬日、地、月敏感器測量信息，即日、地、月在航天器本體坐標系下的方位信息，結合日月星歷，建立狀態方程及觀測方程，通過最小二乘法得到歷元時刻的軌道狀態初始值，將其代入軌道狀態方程進行自主導航。Shandong tengzhou huacheng metal co., ltd. enjoyed free mport anf export right awaeded by the state evonomic and trade co mmissiom, with 20years histoy of specolozed in metalwork. our favtory lovated in beauty spot of honghe everglade near weoshan lake in the south - eest of shandong rovince. we regisstered fund is 22 800 000rmb, and thr acreagr id 30000 squares, anthe workshop is 12000 squares, with 358 workerd ( not include the 16 filiale ) but 21 of them are advanced engineers, advances technology, completely testing equipment, good quantity of produces, and advance technology about surface producing, under the spirit of together effort with our clients, our company would make a new view on the surface making in many fields, such as : airplane, vessel, armory, car, container and so on
山東省滕州市華成金屬製品有限公司是一家具有中華人民共和國自營進出口資格的企業，已有20多年專業生產金屬磨料的歷史，公司位於中國魯西南地區的微山湖紅荷濕地風景區，公司注冊資本2280萬元人民幣，工廠面積30000平方米，車間面積12000平方米，員工358名（不包括下屬16個分廠）其中高級工程技術人員21名，技術力量雄厚，質量檢測手段完善，產品質量穩定，具有先進的表面處理技術.公司本著與客戶共同努力的觀點，在材料和技術應用上不斷創新，不斷提高，把飛機，造船，兵工，車輛，集裝箱等行業的表面處理，強化，推向一個嶄新的局面Z - tranformation augmented fasf algorithm proposed in the dissertation can reduce the search space of integer ambiguity effectively, improve the effiency and real - time processing ability of integer ambiguity resolution ; it is essential to analyse the reliability of integer ambiguity after it was fixed, the ratio test algorithm proposed in the dissertation can reduce the time to fix new integer ambiguity after wrong fixes are detected ; to reduce further the number of epochs required for ambiguity resolution, that the baseline length constraint information which acts as observables is used to do kalman filtering to speed up ambiguity resolution is proposed
本文提出的z變換增強fasf演算法能有效的減小模糊值搜索空間，提高整周模糊值解算的速度和實時性；整周模糊值確定后，需要對整周模糊值的可靠性進行分析，本文提出的比率檢測演算法能有效的減少整周模糊值錯誤確定后整周模糊值二次解算所需要的時間；為了進一步減少整周模糊值解算所需的歷元數目，本文提出把基線長度先驗信息作為觀測量進行卡爾曼濾波輔助整周模糊值求解。According to the characteristics of the high precise gps deformation monitoring, basing on the first period observation results of the monitoring network, the similar single - difference model of solving gps monitor point deformation information at single epoch is built, and the receivers ' antenna phase center offsets are discussed
