PreviSat is a satellite tracking software for observing purposes. Very easy to use, it shows positions of artificial satellites in real-time or manual mode. PreviSat is able to make predictions of their passes, predictions of MetOp and COSMO-SkyMed flares, transits of all satellites, predictions of Starlink satellites passes and several other calculations.

SAGECal is a very fast, memory efficient and GPU accelerated radio interferometric calibration program. It can handle all source models including points, Gaussians and Shapelets. It can calibrate along hundreds of directions without running out of memory in almost real time. Intel Xeon Phi acceleration is also available. Distributed calibration using MPI and consensus optimization is enabled.

WSClean (w-stacking clean) is a fast generic widefield imager. It uses the w-stacking algorithm and can make use of the w-snapshot algorithm. As of Feb 2014, it is 2-12 times faster than CASA's w-projection, depending on the array configuration. It supports full-sky imaging and proper beam correction for homogeneous dipole arrays such as the MWA. WSClean allows Hogbom and Cotton-Schwab cleaning and has wideband, multiscale, compressed sensing and joined-polarization deconvolution modes. ...

FERN is a CUDA program that implements new methods for solving large sets of stiff differential equations using explicit integration methods. For the theory behind the program (due to Mike Guidry), see http://arxiv.org/abs/1112.4778 .

A code for fast multi-dimensional density estimation . Instead of assuming an a-priori metric definition, it calculates a locally adaptive metric for each data point by using, a Shannon Entropy based, binary space partitioning scheme.

N-body implementation of two important algorithm : Tree-code (Barnes-Hut) and FMM (Fast multipole Method). We provide this two algorithm with a new data structure named compressed_octree.

OpenUniverse is a fun, fast and free space simulator. It currently focusses on the Solar System and lets you visit all of its planets, major moons and a vast collection of smaller bodies in realtime 3D (using OpenGL).
