CLASSIFICATION OF GEOSYNCHRONOUS OBJECTS
February 2009 5. Table 3: objects of indeterminate statusThis table contains all the objects the status of which cannot be determined by our software. The main
reason for the difficulty to classify an object is that there are not enough TLEs available or that the status
has recently changed (satellite newly launched or recently manoeuvred). Indeed, at least 5 TLEs with the
same status are needed to determine the category in which the object falls. Some bad measurements can
also cause the failure to classify an object correctly. The objects are ordered according to their COSPAR
designation. The following information is available:
The longitude histories of most objects in this category are plotted in Figures |
