CRITICAL INCLINATION AND FRZEN ORBIT

The critical inclination and the features of the frozen orbit are aspects of interest in the applied orbit theory of the earth satellite and these two topics have been investigated separately. However, these two kinds have the same feature of orbit being frozen, therefore, can be regarded as the same kind of orbit and studied in a unified approach. In this paper the method to seach for the frozen orbit is provided ;the discussion about the stability and motion feature of the orbit is carried out and the relation between the classical solution and the one suitable to the orbit with the inclination near the critical value is also derived.
