Jonathan Diegelman - Modeling Spacecraft Separation Dynamics in Julia

A JuliaCon talk by a NASA Launch Services Program engineer on modeling spacecraft separation dynamics in Julia. He describes replacing a Simulink-based workflow for checking launch vehicle separation requirements with Julia and ModelingToolkit, with large speedups and much shorter code.

Why HN readers recommended it

Cited again and again as the concrete case study behind the claim that NASA got a 15,000x speedup moving from Simulink to Julia.

  • <<was given at a SIAM conference and the recording can be found here: [VIDEO] >> At 14:00, the interactive slider exploration due to the speed is amazing. Over 500 Monte Carlo simulations in less than 60ms.
