Scientific and Engineering
Ground Station
Description:
Open-source satellite ground station software for tracking, SDR control, IQ recording, decoding, and automated observations.
Adun
Description:
High-performance molecular simulations code for biomolecular research.
Xnec2c
Description:
Xnec2c is a high-performance, multi-threaded electromagnetic simulator (NEC2-based) with a GTK3 GUI. It reads NEC2 input files, provides built-in NEC2 editing, and on-demand calculations for antenna radiation patterns, gains, impedance, and VSWR, with visualization of currents and fields.
QSpeakers
Description:
QSpeakers is an open-source loudspeaker enclosure designer for Linux and other platforms, written in C++/Qt. It computes optimal enclosure volumes from Thiele/Small parameters.
openMotor
Description:
openMotor is an open-source internal ballistics simulator for rocket motor experimenters. It estimates a motor’s chamber pressure and thrust from propellant properties, grain geometry, and nozzle specifications, using the Fast Marching Method to simulate grain regression. Features include metric/imperial units, DXF grain loading, propellant editors, and GUI-based design tooling.
