Weak signal ham radio communication
The WSJT project currently includes five programs designed for amateur radio communication using state of the art digital techniques. Typical applications include meteor scatter, EME ("moonbounce"), and QRP communication at HF. Summary Program Descriptions: WSJT: Modes JTMS, FSK441, ISCAT, JT6M, JT65, JT4, Echo, CW. Optimized for meteor scanner, ionospheric scatter, and EME at VHF/UHF/Microwaves. WSJT-X: Modes JT65, JT9. Primarily for use at HF. MAP65: For EME an VHF and higher frequencies. Implements a panoramic, polarization-matching receiver for JT65. WSPR: Probe potential propagation paths using low-power transmissions. WSPR-X: Experimental version of WSPR, including the slow mode WSPR-15. Source code is maintained here SourceForge. For installable end-user packages please go to the WSJT web site at the link below.

Cross-platform, scientific graphics plotting library
PLplot is a cross-platform, scientific graphics plotting library that supports math symbols and human languages (via UTF-8 user input strings); plot capabilities for multiple non-interactive plot file formats and in multiple interactive environments; and bindings for multiple computer languages.
A framework for solving partial differential equations
Overture is a framework for solving partial differential equations (PDEs) in complex, possibly moving geometry. Overture uses overlapping grids to represent the geometry. The software includes grid generation capabilities, PDE solvers for fluids, solids, and fluid-structure interactions (FSI) as well as electromagnetics.
A scientific plotting library for C/Fortran built on cairo
A 2D scientific plotting library built on cairo. Provides uniform output to pdf, ps, png and X-Windows. Written in C with no dependencies (other than cairo) as a direct replacement for PGPLOT.
An integrated atmospheric model for weather and climate prediction and simulation. It includes portable versions of global spectral model, regional spectral model, and non-hydrostatic mesoscale spectral model.
The PDL module gives standard perl the ability to COMPACTLY store and SPEEDILY manipulate the large N-dimensional data sets that are the bread and butter of scientific computing.
View, manipulate, analyze (LS fit, SVD, FT), and make figs of, spectra
Program for viewing, editing, manipulating, and analyzing absorbance spectra. Simple arithnetic includes making linear combinatins of up to 10 spectra. Advanced functions include fitting spectra as LC of standard basis spectra, singular value decomposition, Fourier transform, differentiation, integration, global fitting of 3D titration and kinetic data. Graphics features allow composing Figures and export to postscript files which can be converted to pdf, imported into photoshop for rasterization, or used in page design software like Illustrator.

PHIGS (Programmer's Hierarchical Interactive Graphics System)
PHIGS is an API standard for rendering 3D computer graphics. During the 1990's OpenGL became a more popular 3D API for professionals, and it still is today. PHIGS remains to be widely used in the film industry. Open PHIGS uses OpenGL for rendering graphics rather than implementing it's own abstraction layer to the graphics hardware, or using the PHIGS Extension to X (PEX). The reason for doing so is that today every graphics card manufacturer provides their own OpenGL implementation, which takes full advantage of the accelerated drawing capabilities in the hardware. PHIGS is a higher level API than OpenGL that works with a hierarchical scene graph. Models are built up in a Centralized Structure Store (CSS), a database containing the drawing primitives and their attributes (color, line style, etc.). CSSes cand be shared among a number of views, known under PHIGS as a workstation. PHIGS is defined by the ISO standards ISO/IEC 9592 & 9593. Open PHIGS provides a library for C.

Source Navigator NG is a source code analysis tool. With it, you can edit your source code, display relationships between classes and functions and members, and display call trees. You can navigate your source code and easily get to declarations or implementations of functions, variables and macros (commonly called "symbols") which helps you discovering and mapping unknown source code for enhancement or maintenance tasks.
