| Abstract: | The problem of the mathematical model of the attitude correction of scanning horizon sensor for the earth oblateness is discussed in present paper.An analytical formula of attitude measuring error is obtained and can be used as attitude correction for arbitrary orbital elements and arbitrary installing angle of the scanning axis.A numerical example is given and shows that the results of analytical method and numerical method are identical perfactly. |
