The .zip file containing the dataset is organized as follows:
deb_train/ a folder containing trajectories of 100 space debris denoted by their orbital elements as a help to study the problem.
deb_test/ same as deb_train but with different debris that will be evaluated during the competition
sat/ a folder containing 100 trajectories of defunct satellites
labels_train.dat: a text-file containing the origin and the area to mass ratio of the debris pieces from deb_train
All text-files inside deb_train, deb_test and sat use the same encoding to describe the orbital elements of the debris pieces or satellites. The format of the columns (in order) is the following:
Epoch (in days: 0 means JD2000 at 12 Noon)
Semimajor axis (in km)
Eccentricity (0 to 1)
Inclination (in degrees)
Mean anomaly (in degrees)
Argument of the perigee (in degrees)
RAAN (in degrees)
All orbital elements are computed in the EME2000 equatorial reference frame
Each of the 100 rows in the file labels_train.dat corresponds to a debris piece from deb_train and describes the event that generated the debris piece (row 1 corresponds to deb_train/eledebtrain001.dat, row 2 to deb_train/eledebtrain002.dat and so on).
The first column of each row describes the id of the satellite (origin of the debris, corresponding to sat/elesatxxx.dat). The second column describes the area to mass ratio of the debris and the third column the epoch at which the debris was generated. All remaining columns describe again the orbital elements of the debris at this epoch and are given for convenience.
