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.”

About Julia and Julia Computing

Julia is the fastest high performance open source computing language for data, analytics, algorithmic trading, machine learning, artificial intelligence, and other scientific and numeric computing applications. Julia solves the two language problem by combining the ease of use of Python and R with the speed of C++. Julia provides parallel computing capabilities out of the box and unlimited scalability with minimal effort. Julia has been downloaded by users at more than 10,000 companies and is used at more than 1,500 universities. Julia co-creators are the winners of the 2019 James H. Wilkinson Prize for Numerical Software and the 2019 Sidney Fernbach Award. Julia has run at petascale on 650,000 cores with 1.3 million threads to analyze over 56 terabytes of data using Cori, one of the ten largest and most powerful supercomputers in the world.

Julia Computing was founded in 2015 by all the creators of Julia to develop products and provide professional services for businesses and researchers using Julia.
