In order to correct the geocentric distance's error of TDI (Time Delay and Integration) CCD space camera in calculation of image motion compensation  the data source of the earth's height above sea level USGS DEM (United States Geological Survey Digital Elevation Model) has been introduced to make digital elevation map  the match error of the forward direction (the integral direction of TDI CCD) has been greatly decreased by correcting the geocentric distance error  and eliminate the influence to the relative error of image motion velocity  and correct the error generated by the different heights above sea level. After correcting  which greatly improves the imaging quality of TDI CCD space camera. 2011 IEEE.  a model of image motion calculation of nadir has been introduced  the calculation and analysis of the model shows that: the maximum error of image motion velocity about 1.72% has been decreased to 0.06%  and the influence of the geocentric distance error to the relative error of image motion velocity has been analyzed with the model

Two kinds of design methods of GPS/INS integrated navigation system are presented  that is GPS/INS integrative system and integrated navigation system based on information fusion. By analyzing mathematics model of the first system error  we found that inertia velocity error would cause code loop track error. Consequently  the pseudo range meterage error is interrelated with inertia velocity error  which is complex to calculate. If this relativity is ignored in the state equation and observation equation of this system  it must affect the estimated precision of the kalman filter and maybe the system is unstable. Therefore  the second integrated navigation method is introduced. It adopts information fusion  federal kalman filter and covariance. And consider the above pertinence to analyze the navigation performance of the integration system. Then it gives the flow of federal kalman filter algorithm. By analyzing  the conclusion is that velocity error of integrated navigation system drops from 0.5m/s to below 0.05m/s  and improves the precision and reliability of the navigation system effectively  well continuity and real-time capability. It provides an effective way for data analysis and process of fusion navigation system. 2006 IEEE.
