CLASSIFICATION OF GEOSYNCHRONOUS OBJECTS
February 2007 3.6 Objects in a libration orbit around both stable pointsIn the case where the object is in a libration orbit around both stable points, the following data are given:
It is important to note that this category is special and only a very small number of objects is concerned. It is a borderline case, just between a libration around one stable point and a drift around the Earth. Thus, some perturbations which could be neglected in the other cases have a strong influence here. The main consequence is that this category is more sensitive to errors in the measurements than the others and the libration period may have a low accuracy.
The longitude history of these objects is plotted in Figures 1. |
