| Abstract: | This paper deduces elevation error estimating formulae of the satellite photogrammetry,which is concerned with elements of exterior orientation that measured by spaceborne sensors.According to the attitude stability of two-line array CCD pushbroom image at 10 -6o/s,or lower than 10 -6o/s and the attitude stability of so called LMCCD (line-matrix CCD camara) pushbroom image lower than 10 -6o/s,the authors deduce and calculate for different cases respectively,and present an example for each estimating formula for the application of designing satellite photogrammetry engineering system without ground control point. |
