Satellite Launched Into Space Using Julia: Ronan Arraes Jardim Chagas is the “mission architect and technician responsible for the altitude and orbit control subsystem (AOCS) for the Brazilian satellite Amazonia-1, launched on Feb 28.” He explains that Julia is used for:

• 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 problem with AOCS is that you often need to get a lot of data from the satellite telemetry and plot many graphics. During the integration and testing, I needed to do this daily. Hence, we developed inside INPE a Julia package that automatically fetches the raw telemetry from the database, process, and output what we want. Today I can very easily see the overall satellite AOCS state with just two or three commands.

• The in-orbit sensor calibration required the implementation of Kalman filters, which, of course, was coded in Julia.

Furthermore, “We can now say that Julia is truly a part of the Brazilian space program. Finally, I want to thank all you developers that created Julia and the fantastic package ecosystem. It really made a lot of difference to me! I am 100% sure that I would have a lot more work if I had to use another computing language.”
