Space Debris: the origin dataset

The "Space debris: the origin" dataset is the official dataset of ESA's Kelvins competition of the same name. The objective of this challenge is to trace the origin of space debris based on some sparse observations back to one of 100 potential originator satellites. The observations of the space debris consist of an epoch (JD2000) and the corresponding orbital elements in the following order:

• Semimajor axis (in km)
• Eccentricity (0 to 1)
• Inclination (in degrees)
• Mean anomaly (in degrees)
• Argument of the perigee (in degrees)
• RAAN (in degrees)

For each debris in the subfolder deb_train the id of the originator satellite is given in the first column of labels_train.dat, followed by its area over to mass ratio. The competition asks its participants to recover these two values for all debris observations in the deb_test subfolder. The orbital elements of the satellites are denoted in the subfolder sat.
