abstract = "The concept of frozen orbit has been applied in space missions
mainly for orbital tracking and control purposes. This type of
orbit is important for orbit design because it is characterized by
keeping the argument of perigee and eccentricity constant on
average, so that, for a given latitude, the satellite always
passes at the same altitude, benefiting the users through this
regularity. Here, the system of nonlinear differential equations
describing the motion is studied, and the effects of geopotential
and atmospheric drag perturbations on frozen orbits are taken into
account. Explicit analytical expressions for secular and long
period perturbations terms are obtained for the eccentricity and
the argument of perigee. The classical equations of Brouwer and
Brouwer and Hori theories are used. Nonsingular variables approach
is used, which allows obtaining more precise previsions for CBERS
(China Brazil Earth Resources Satellite) satellites family and
similar satellites (SPOT, Landsat, ERS, and IRS) orbital
evolution. © 2014 Paula Cristiane Pinto Mesquita Pardal et al.",
