1.	Which of the following is not one of the perturbations that make the satellite to vary from its elliptical path?(a) Solar activity(b) Asymmetrical components of Earth’s gravitational field(c) Air drag(d) Motion of a passing cometI got this question in my homework.My query is from Orbital Mechanics and Clock Characteristics topic in portion Satellite Radio Navigation& Inertial Navigation of Avionics
Answer» Correct answer is (d) Motion of a PASSING comet The explanation is: Perturbations cause the ORBITAL plane to oscillate and rotate and VARY the SATELLITE from its elliptical orbital path. These forces include spherical asymmetrical components of Earth’s gravitational field, Lunisolar perturbations, air drag, magnetic and STATIC electric forces.
