Nobody is using Julia (yet) to control a satellite (i.e. running Julia code on a satellite, to fully or partially control), that I know of, but Julia helped launch Brazil’s Amazonia-1 satellite (e.g. the “in-orbit sensor calibration”, that I at least think runs on the ground):

> Hi guys! Long time, no see! As some of you may know, I am the mission architect and the technical responsible for the attitude and orbit control subsystem (AOCS) of the Brazilian satellite Amazonia-1, launched on Feb 28. This is an image obtained by the first recording procedure: Here you can see the big city of São Paulo (on the left), São José dos Campos where INPE is located (“small” city on the top right), and the beautiful Brazilian shore, showing San…

> - General mission analysis such as fuel budget computation, orbit planning, ground station visibility analysis, etc.
> - The Amazonia-1 AOCS simulator is 100% written in Julia using the amazing DifferentialEquations.jl ecosystem. The results obtained from it greatly match the real satellite dynamics obtained after the orbit injection.
> - The AOCS telemetry analysis system is also 100% written in Julia. […]
> - The in-orbit sensor calibration required the implementation of Kalman filters, which, of course, was coded in Julia.

> We can now say that Julia is truly a part of the Brazilian space program 🙂

> JuliaSpace has 25 repositories available. Follow their code on GitHub.

> This package contains several functions to build simulations related with satellites. It is used on a daily basis on projects at the [Brazilian National Institute for Space Research (INPE)](http://www.inpe.br)
