To solve the non-uniformity problem of multi Time Delay Integral Charge Couple Device (TDICCD) mosaic camera several common non-uniformity correction methods are discussed. Secondly a non-uniformity correction algorithm is proposed and implemented on Field-Programmable Gate Array (FPGA) platform. Firstly the correction algorithm is designed. Finally the generation and definition of non-uniformity are introduced considering the fix-point processing ability of FPGA the correction algorithm is optimized properly and implemented on FPGA. The experimental results indicate that the non-uniformity can be decreased from 8.3%to 2.0% in 1s for 3-TDICCD mosaic camera's images with the proposed correction algorithm at 96TDI stage proving that this correction algorithm is of high real-time performance good practicality and satisfies the requirements of the target system. 2010 IEEE.

The Earth's digital elevation which impacts space camera imaging has prepared and imaging has analysed. Based on matching error that TDI CCD integral series request of the speed of image motion statistical experimental methods-Monte Carlo method is used to calculate the distribution histogram of Earth's elevation in image motion compensated model which includes satellite attitude changes orbital angular rate changes latitude longitude and the orbital inclination changes. And then elevation information of the earth's surface from SRTM is read. Earth elevation map which produced for aerospace electronic cameras is compressed and spliced. It can get elevation data from flash according to the shooting point of latitude and longitude. If elevation data between two data the ways of searching data uses linear interpolation. Linear interpolation can better meet the rugged mountains and hills changing requests. At last the deviant framework and camera controller are used to test the character of deviant angle errors TDI CCD camera simulation system with the material point corresponding to imaging point model is used to analyze the imaging's MTF and mutual correlation similarity measure simulation system use adding cumulation which TDI CCD imaging exceeded the corresponding pixel horizontal and vertical offset to simulate camera imaging when stability of satellite attitude changes. This process is practicality. It can effectively control the camera memory space and meet a very good precision TDI CCD camera in the request matches the speed of image motion and imaging. 2010 SPIE.

North-finding system provides true north azimuth information to all kinds of ground-based equipment. A dynamic automatic north-finder based on the modulation output of fiber optic gyroscope (FOG) is presented in this paper. In this scheme the sine output signal of the FOG was sampled and disposed and then the real north of surveyed point on the surface of earth was calculated. The deviation caused by the platform base tilt was compensated by an accelerator Allan standard deviation is used to analyze the random drift of FOG and establish the random error mode of FOG. The FOG north-finding and laser collimation theodolite are assembled to achieve orientation and aiming integral which lays foundation for switching to project application. 2007 IEEE.
