                         debris justifying the interest in the observation and collision 
                         avoidance. The orbital dynamics of several of these objects 
                         involve different resonances distributed by the distinct 
                         altitudes. In this work, objects in resonant orbital motions in 
                         the regions of 14:1 and 15:1 resonances are studied. Using the 
                         two-line elements (TLE) of the NORAD, resonant angles are 
                         described to develop an analytical model and the time behaviors of 
                         the orbital elements. Frequency analysis shows possible irregular 
                         motions describing the orbital motions of these objects.",
