Abstract: This paper presents the formula of the initial values of theorbital parameters—celestial longitude φ_0 of the sun,right ascension ofascending node Ω_0 and argument of perigee ω_0,used for calculating orbitalheat flux received by satellite.The accuracy of calculation of these para-meters has met the requirements of thermal analysis of a satellite.
