A wavelength-independent absorption coefficient model which consists of a combination of the Planck, Rosseland and Gray-gas approximations (PRG model) is developed. Accuracy of the model is assessed by comparing with a line-by-line calculation and a multiband model. The comparison is made for one-dimensional radiative transport along the stagnation streamline for typical spacecrafts entering Earth, Mars, Venus, and Jupiter. The developed model closely reproduce both the heat flux values reaching wall and the distribution of the radiative heat flux values.
