The 2:1 resonance is considered; in other words, the satellite completes two revolutions while the Earth completes one. In the development of the geopotential, the zonal harmonics J(20) and J(40) and the tesseral harmonics J(22) and J(42) are considered. The order of the dynamical system is reduced through successive Mathieu transformations, and the final system is solved by numerical integration. The Lyapunov exponents are used as tool to analyze the chaotic orbits.22engThe Orbital Dynamics of Synchronous Satellites: Irregular Motions in the 2:1 ResonanceArtigo10.1155/2012/405870WOS:000299533000001Acesso abertoWOS000299533000001.pdf77409171447574100000-0003-1289-8332
