In order to improve the alignment precision and convergence speed of strap-down inertial navigation system  but in the active system most noise statistical characteristics are unknown  an initial alignment method based on Sage-Husa adaptive filter is presented. We also derived the exactitude alignment error model and adaptive Kalman filter equation in the azimuth of small misalignment angle. As usual  in this case  known the noise statistical characteristics  we introduce the adaptive Kalman filter. It uses the information of observed data  Kalman filter is suitable  on-line estimation noise statistical characteristics and state simultaneously in order to improve the filter continuously  so  the filter has a higher estimation accuracy than the conventional Kalman filter. By simulating verifying  the adaptive Kalman filter enhances the convergence speed and alignment accuracy effectively.

The surface profile of Wolter type-I mirror has a great impact on the performance of Solar X-ray Telescope. According to the existing fabrication instrument and experimental conditions in our lab  an in situ Long Trace Profiler is developed and set up on the fabrication instrument in order to measure the surface profile of Wolter mirror in real time during fabrication process. Its working mechanism  structural parameters and data processing algorithm are investigated. The prototype calibrated by a standard plane mirror is used to measure a sample of Wolter type-I mirror. The results show that our prototype can achieve an accuracy of 2.6rad rms for slope error with a stability of 1.33rad during the whole measurement period. This can meet further fabrication requirements. 2010 Copyright SPIE - The International Society for Optical Engineering.
