  1. The maximum likelihood registration algorithm based on earth - centered earth - fixed ( ecef ) coordinate system considers the geometry of the global, and eliminates errors introduced by the stereographic projection. the simulation result based on this registration algorithm shows that the satisfied angular biases can be preliminarily obtained. 5

    基於地心坐標系的傳感器極大似然配準演算法考慮到了地球曲率的影響，克服了立體投影法的缺陷；採用這種演算法，我們可以把不同傳感器局域坐標系的量測轉化到地心坐標系中，變成統一的量測，便於融合中心做進一步的處理；模擬結果表明這種演算法可以得到較為滿意的角度偏差。
  2. Because the earth is a non - outspread sphere, plane vector visualization will induce some errors. we analyze its problems, and propose a vector display method based on cartography and in the sphere coordinate system, evolve the formula. we make experiments and prove the formula is right, new method can get better vector display

    本文對直接表示方法存在的問題進行了討論，提出了一種新的基於地圖投影的向量可視化方法，並給出了球坐標系下的向量可視化方法，推導出坐標和向量的變換公式。
  3. Based on the duncan - chang e - b model, which can simulate earth - rock dam ' s non - linear mechanics behavior well, the paper introduced the nature coordinate system to the stress space. in this way, hydrostatic stress and stress deviator were decomposed each other. therefore, a partial derivative formulation about displacement and parameter in finite element evaluation was derived in a closed form

    論文以能較好模擬土石壩非線性力學行為的duncan - change - b模型為基礎，通過引入應力空間下的自然坐標系，分解應力球量與應力偏量，從而導出一個在有限元計算中，位移對參數偏導數的閉合形式公式。
  4. Gps receiver message of localization based on u. s. a. wgs84 coordinate system of the earth " s core, map of our country drawn and made according to 1954 - beijing geodetic coordinate system. in order to improve the precision, need to carry on coordinates transformation

    Gps接收機的定位信息是基於美國地心坐標系的wgs84坐標，而我國的地圖多根據1954年北京坐標系測繪製作，為了提高定位的精度，需要進行坐標轉換。
  5. Two spacecraft ’ s rendezvous technology in coplanar near - earth orbit with maneuvering target, based on the sight coordinate system is presented in this paper. differential games guidance law ( dggl ) and proportional navigation ( pn ) are studied

    本論文研究了近地共面軌道兩空間飛行器在目標機動下的在軌交會技術，分別對微分對策制導律和比例導引制導律兩種制導方法進行了研究。
