How Satellite Collision Prediction Works: SGP4, TLEs, and KD-Trees
A technical deep-dive into the algorithms behind collision prediction — from TLE data ingestion and batch SGP4 propagation to KD-tree spatial indexing that screens 14,368 objects in 5.8 seconds.

There are 14,368 active objects in orbit. Every day, hundreds pass within kilometers of each other. We screened the entire catalog in under 6 seconds and found 441 real collision threats — including Hubble with no way to dodge, and cross-operator close calls at 11.55 km/s.
