Ongoing Projects

Listed here are the currently ongoing projects. (The list is not necessarily exhaustive and will be updated regularly.)

1U/2U Structure

The goal of this project is to develop a modular structure that fully conforms to the CubeSat Design Specification and allows for housing of LibreCube boards. If shall provide fixation points for solar panels and/or external structures and shall be designed as such to allow a quick and easy removal of interior boards without the need of structure disassembly.

LibreSim

This is a larger project to develop a simulator infrastructure that can be used to simulate any kind of (space) mission. It is implemented in Python and follows the recommendations provided in the ECSS Standard ECSS-E-ST-40-07C. The core of LibreSim is a kernel to run simulations based on discrete-event simulation (using SimPy), which has reached sufficient maturity.

The major part of work is now on the development of the model library. The models of those libraries can then be used to assembly a system to be simulated. For this, there are libraries for common models, that can be used to model thermal behavior, dynamics, coordinate systems, electrical behavior, and so on. The next higher layer are the generic models, that represent typical systems used in space mission architectures, such as electrical power supply, attitude control, and radio communications. They are defined in a generic way and need to be adapted to simulate concrete physical systems.

Another important aspect of this project is visualization of the simulation output. For, we are exploring the use of Grafana with LibreSim timeseries store and a browser-based 3D viewer.

PLUTO

This is a Python module for converting PLUTO scripts into native Python code. PLUTO stands for Procedure Language for Users in Test and Operations and is a domain specific language (DSL). It was developed by the European Cooperation for Space Standardization for the automation of procedures in the development and utilization of space systems (but not limited to it).
