Simple, Scalable, Script-based Science Processor for Measurements

http://sourceforge.net/projects/s4pm/files/latest/download

The Simple, Scalable, Script-based Science Processor for Measurements (S4PM) is a system for highly automated processing of science data, scalable up to large processing systems and scalable down to small, special-purpose processing strings.

Goddard Satellite Data Simulation Unit

http://opensource.gsfc.nasa.gov/projects/G-SDSU/

G-SDSU core modules enables users to insert their own satellite simulator to convert model-simulated atmosphere states to various types of satellite observable signals (radiance or backscattering signals), and to compare such data with comparable measurements collected by corresponding satellite level-1 measurement.

Core HSEG Software Package

http://opensource.gsfc.nasa.gov/projects/HSEG/

The RHSEG software provides hierarchical segmentation (pre-processing) of image and image-like data. The software significantly improves the extraction of patterns from complex data sets and is optimized for speed and accuracy. This algorithm provides the user with precise control for selecting the desired level of detail from the hierarchy of results.

Visual System for Browsing, Analysis and Retrieval of Data (ViSBARD)

http://sourceforge.net/projects/visbard/

ViSBARD (Visual System for Browsing, Analysis, and Retrieval of Data) is an interactive visualization and analysis tool for space physics data. It provides an integrated 3-D/2-D environment to analyze measurements across many spacecraft and MHD models.

Ground and space radar volume matching and comparison software

http://opensource.gsfc.nasa.gov/projects/GSRadar/

This software enables easy comparison of ground- and space-based radar observations. The software was initially designed to compare ground radar reflectivity from operational, ground-based, S- and C-band meteorological radars with comparable measurements from the Tropical Rainfall Measuring Mission satellite’s Precipitation Radar instrument. The software is also applicable to other ground-based and space-based radars. The software […]

Orbit Determination Toolbox

http://opensource.gsfc.nasa.gov/projects/ODTBX

ODTBX is an orbit determination analysis tool based on Matlab and Java that provides a flexible way to do early mission analysis, especially for formation flying and exploration systems. ODTBX is composed of both Matlab and Java code.

International Polar Orbiter Processing Package (IPOPP)

http://directreadout.sci.gsfc.nasa.gov/index.cfm?section=downloads&page=technology

The International Polar Orbiter Processing Package (IPOPP) is the primary processing package that will enable the Direct Readout community to process, visualize, and evaluate National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) Sensor and Environmental Data Records, which is a necessity for the Direct Readout community during the transition from the Earth Observing […]

Global Precipitation Radar (GPM) space and ground radar comparison software

http://opensource.gsfc.nasa.gov/projects/GPM/

NASA’s Global Precipitation Missions (GPM) is designed as a constellation of satellites to measure precipitation with a 3-hour average revisit time over 80% of the globe, and the data will be available to users within 3 hours of observation time. A Ground Validation System (GVS) is an integral part of GPM.

GEOS-5 GCM Modeling Software

http://opensource.gsfc.nasa.gov/projects/GEOS-5/

The Global Modeling and Assimilation Office (GMAO) has delivered the next generation general circulation model, GEOS-5. This system represents a new paradigm for systems development, in that GEOS-5 has been developed with the Earth System Modeling Framework (ESMF) for its internal architecture using the MAPL software toolkit developed for GEOS-5.

General Mission Analysis Tool

http://gmat.gsfc.nasa.gov/

The General Mission Analysis Tool (GMAT) is an open-source space mission analysis and design tool being developed by a team made up of NASA, private industry, and a range of academic, public, and private contributors. GMAT is intended both for real-world engineering design studies and as a tool for education and public engagement in the […]
