Abstract: In the paper, the mathematical equations for the output signals of the stellar meridian observation are presented via analysing the processes of the observation. The output signals of the stellar meridian observation using a photon counter are obtained by means of combining the computed signals wiry recording noises. Two practical problems in meridian observation are dicussed and solved with the simulating method.

Key words: meridian observation, photon counting, simulation, computer
