Abstract: Defining the location and structure of airglow needs tomographic data processing of photometric measurements. The Cormack inversion is used for tomographic reconstruction of airglow. Both the observed function of column brigthness and the volume emission rate function of airglow may be expanded in a Fourier series. The inversion allows the Fourier coefficients of volume emission rate function to be obtained using the Fourier coefficients of the observed function of column brigthness. The software was developed, and a numerical simulation of onboard observations and their tomographic processing was made.
