A lightweight extensible spacecraft commanding & telemetry processing framework

F´ - A flight software and embedded systems framework

The Common Model Library. CML provides a collection of generic, verified, validated, and reusable C++ models of spacecraft that are compatible with NASA's Trick Simulation Environment.

Observational Products for End-Users from Remote Sensing Analysis (OPERA)

Trick Simulation Environment. Trick provides a common set of simulation capabilities and utilities to build simulations automatically.

A lightweight XML-based framework for building real-time display applications and cockpit interfaces.

Provide a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station.

CEA computes the equilibrium composition of mixtures via free-energy minimization, and uses the resulting product concentrations to determine thermodynamic and transport properties. It includes a large database of species with thermodynamic curve-fit data, and can be used for rocket performance, detonation parameters, and shock-wave analysis.
