This is a raw version with minimum of comments and rather unclear structure. The code is being cleaned up and commented properly and will be updated soon.

There is a break-up model (breakup.py) and collision model (cube_2agents.py) which is based on CUBE method for evaluating probability of collision of two objects.

You can run the model by running the main class cube_2agents.py. To run this model successfully you will need to install PyKEP scientific library available at https://esa.github.io/pykep/.

The initial setting is:

time horizon - 150 years
US removes 1 risky object every two years
EU, China and Russia do not remove any objects

Input (publicly available):

SATCAT - satellite catalogue
TLE - two-line element set database

Output:

There are 3 output files:
(i)
Number of objects every year of the simulation
Number of catastrophic and non-catastrophic collisions
Total number of debris

(ii)
Collisions of important assets for each of the players
Risks to important assets
Number of important assets for each of the players

(iii)
List of removed objects
