	Design of data transmission speed for small high resolution satellite (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Transportation, Mechanical, and Electrical Engineering, TMEE 2011, December 16, 2011 - December 18, 2011, Changchun, China Wang S.; Jin G. 收藏 \| 浏览/下载：43/0 \| 提交时间：2013/03/25 The particular data-transmission time of one small satellite in its data-receiving stations is given by simulateing its orbit and data-receiving stations on earth and the average data-transmission speed is calculated. The average data-transmission speed is taken as the lower limit of speed other different data-transmission speeds are selected and simulated respectively the rule of satellite memory used is found. Basing on the relationship between data-transmission speed and memory on board and considering the worst case the better speed arrived. In the end with different satellite tasks the appropriate speeds are selected which are verified to satisfy the mission. 2011 IEEE.
	Measuring system on 3-D pose of the remote revolving target based on intersection measurment and its precision analysis (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Information Processing, August 21, 2005 - August 26, 2005, Changchun, China Li Q.-A.; Li X.-R.; Liang C.-P.; Qiao Y.-F. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 In this paper a method of measuring the 3-D pose of the remote revolving target such as rocket or missile by using the intersected measuring system with a proper algorithm is described. This passage creates a math model of intersected measuring system with dual - photoelectric theodolite and the formula to calculate the target attitude angles are presented.The measuring precision of this method is analyzed in detail by using the relative error theory and then it makes optimization design for structure parameters of intersected measuring system with dual - photoelectric theodolite by computer simulation so different optimization results according to different location of target are obtained and the system lay-out measuring principles are also presented. By using this method we may acquire the measuring precision higher than 0.5 if the measuring stations are arranged correctly.
