cascade
As the number of artificial satellites orbiting our planet grows, the likelihood of collisions increases, potentially triggering a cascade effect making certain orbits unusable.
cascade is a C++/Python library developed to propagate the evolution of large number of orbiting objects while detecting reliably close encounters and collisions. It is coded in modern C++20 with focus on the efficency of the underlying N-body simulation with collision/conjunction detection. Its development was motivated to help conjunction tracking and collision detection of orbiting space debris populations.
Notable features include:
- a new and original collision detection algorithm based on high order Taylor expansions,
- guaranteed detection of all occuring collisions and conjunctions, high precision orbital propagation via Taylor integration,
- possibility to define custom dynamics,
- automatic usage of modern SIMD instruction sets (including AVX/AVX2/AVX-512/Neon/VSX),
- automatic multi-threaded parallelisation.
