The effects the earth, sun and moon attraction on satellite's orbital motion

الملخص EN

Computer simulation of orbit estimation satellites has been developed.

The combined effects of the 2J zonal harmonics of the Earth gravitational field and the sun and moon attraction effects on the orbital elements, the right ascension of ascending nodes and the argument of perigee, were investigated.

Orbit estimation is based on the iterative solution of Kepler's equation by using Newton method.
