| Abstract: | The ray refraction effect of the atmosphere was mainly studied. At first derive the equation of ray way of atmosphere in brief, then introduce the physics-noun mengqicha, calculate the deflection angle of the up chain and down chain respectively, and explain why the deflection angle exist and put forward the feasible method to dispel the angle;through improve the angle of departure make light can up to the reception station of satellites just after the deflection. |
