Adjusting the drift angles of a space camera on real time in photographing could decrease the influence of the attitude change on image quality and could prolong continuous photographic time with more TDI integral progressions.In this paper,the requirements adjusting drift angles on real-time were analyzed in detail and the real-time adjusting tactics were presented.Then,the structure of a drift angle adjusting system and the operating principle of real-time adjusting were introduced.Finally,a batch-type real-time adjusting method was presented and experimented.Experimental results indicate that the partial difference of drift angle can be adjusted to below 4.2′ with the adjusting error no larger than 72.17″ and the adjusting time less than 1 s.Moreover,Modulation Transfer Function(MTF) of the image is 99.67%,while the drift angles are adjusted.These results show that the proposed method can meet the requirements for adjusting drift angles on real-time and long period without essential influence on images in photographing process.
