Based on the needs of agility small satellites  this article explained the method of SGCMG principle prototype design and proposed the influence on SGCMG output torque precision generated by time accumulation error first time. This article provided a new idea for future SGCMG project development and had good reference value for SGCMG research. 2011 IEEE.   Electronic system design of ultraviolet ozone vertical profile probe for aerography satellite (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Electronic and Mechanical Engineering and Information Technology, EMEIT 2011, August 12, 2011 - August 14, 2011, Harbin, China Song K.; Wang S. 收藏  |  浏览/下载：15/0  |  提交时间：2013/03/25 The design of ultraviolet ozone vertical profile probe is illustrated and the electronic system is introduced in detail. The device is a compact  high precision  ultraviolet-vacuum  ultraviolet spectral radiometer  and is used to measure atmospheric solar backscattering spectral radiance and solar spectral irradiance. Noise of the system is analyzed and Numeric accumulation and synchronous demodulation was used to decrease the noise and the zero-drift of the instrument. The solar irradiance at altitude 830 km in 160-400 nm and the backscattering solar spectral radiance in the ultraviolet ozone absorption band at 12 wavelengths from 250 nm to 340 nm are obtained. Test results on orbit show that all the requested function is met successfully and the performance is stable. 2011 IEEE.   Influence of debris flow on channel evolution 会议论文  OAI收割 Padua, 2011 作者:  Liu, Jiankang;  Cheng, Zunlan;  Zhang, Xiaogang   |  收藏  |  浏览/下载：22/0  |  提交时间：2018/11/08 Accumulation rates  Debris flow fan  Fixed point observations  Genesis and evolution  Jiangjia Gully  Lithological features  Transverse profile  Transverse section   High accuracy star image locating and imaging calibration for star sensor technology (EI CONFERENCE) 会议论文  OAI收割 6th International Symposium on Precision Engineering Measurements and Instrumentation, August 8, 2010 - August 11, 2010, Hangzhou, China 作者:  Wang Y.;  Wang Y.;  Wang Y.;  Wang Y. 收藏  |  浏览/下载：12/0  |  提交时间：2013/03/25 Today aircraft attitude measurement technology plays an important role in an aircraft system because it can provide orientation for aircraft in action. Lately star sensor technology used in aircraft attitude measurement has become more and more popular because of its high accuracy  light weight  without attitude accumulation errors and other advantages. There are three main steps for star sensor to measure aircraft attitude  star image locating  star identification and attitude tracking. The latter two steps are based on the accuracy of star image locating. So it's critical to make efforts to advance the accuracy of star image locating. Some imaging errors  such as spherical aberration or coma aberration  also have negative effect on the accuracy of star image locating  of which the effect is necessarily reduced as well. At the beginning of this article  the structure of star sensor hardware is introduced. Secondly three methods for star image locating are described specifically  which are traditional centroid method  Gauss quadric fitting method and improved Gauss quadric fitting method. Subsequently an imaging calibration method is described for the purpose of reducing the effect of imaging errors. Finally the experiment shows that the accuracy of the star sensor is 2-arc-second. 2010 SPIE.   Design of high precision star image locating method used in star sensor technology (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者:  Sun H.;  Wang Y.;  Wang Y. 收藏  |  浏览/下载：50/0  |  提交时间：2013/03/25 Nowadays star sensor technology used in aircraft attitude measurement has become more and more popular for its high precision  light weight  without attitude accumulation errors and other advantages. In order to enhance the accuracy of star sensor  it is critical to make efforts to promote the precision of star image locating. High precision star image locating method mentioned in this article includes two aspects. One is sub-pixel dividing algorithm used to acquire the coordinate of stars. The other one is imaging calibration method used to weaken the effect caused by imaging distortion. This method is finally realized in some type of star sensor system. Then an experiment is designed to verify the precision of the method. The result of the experiment shows that the precision of the method is 2" in the experimental environment. 2010 IEEE.
