The Orbit Determination Toolbox (ODTBX) 2012a (v5.0) is an advanced mission simulation and analysis tool used for concept exploration, proposal, early design phase, or rapid design center environments: the emphasis is on flexibility, but it has enough fidelity to produce credible results. ODTBX v5.0 includes...

This project investigated advanced navigation strategies required to approach, perform proximity operations, and return a sample from an asteroid or comet. An optimized navigation strategy for a notional mission to a near-Earth asteroid was developed to serve as...

A report describes a self-stabilizing distributed clock synchronization protocol in the absence of faults in the system. It is focused on the distributed clock synchronization of an arbitrary, non-partitioned digraph ranging from fully connected to 1-connected...

Outlier or anomaly detection refers to the task of identifying abnormal or inconsistent patterns from a dataset. While they may seem to be undesirable entities, identifying them has many potential applications in fraud and intrusion detection, medical research, and safety-critical...

Simple RunTime eXecutive (SRTX) software provides scheduling and publish/subscribe data transfer services. The scheduler allows dynamic allocation of real-time periodic and asynchronous tasks across homogeneous multi core/multiprocessor systems. Most real-time systems assign tasks to specific cores on an a priori...

CODE is a framework for control and observation in distributed environments. The framework enables the observation of resources (computer systems, storage systems, networks, and so on), services (database servers, application execution, servers, file transfer servers,...

Geometry Manipulation Protocol (GMP) is a library that serializes data types between XML and ANSI C data structures to support computational fluid dynamics (CFD) applications. This library currently provides a description of geometric configurations, general moving-body scenarios (prescribed...

The NASA Space Telecommunications Radio System (STRS) specification cites a plan for an application repository, similar to an “app store,” but with a wide variety of licensing restrictions on access to different applications, and even different parts of...

The spherical empirical mode decomposition algorithm is an adaptation in the spherical space of the 2D empirical mode decomposition in Euclidian space. This algorithm is a signal analysis method for any spherical data, such as orbital measurements. The two primary advantages of this innovation are the absence...

The Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) is an Earth imaging radar that flies on a Gulf-Stream Jet. Its mission is to collect data for NASA scientists who are using Synthetic Aperture Radar to develop methods for monitoring changes in the Earth’s surface. As with many...

The analysis and simulation of gases expanding from sources such as rocket nozzles into vacuum, or the effects plumes from these sources create when they interact with solid surfaces, present a considerable challenge to the scientific and engineering communities. As a...

Model-Based System Engineering is becoming widely adopted at JPL and in industry because model-centric systems introduce improved methods of system engineering. As systems with ever-increasing complexity are developed at JPL, model-centric engineering be comes essential for design,...

SIVO-PyD gathers and automatically installs (in various computing platforms) a collection of Python-related packages for scientific computing and visualization. All of the packages in distribution are accessible within the Python framework. The distribution is self-contained and...

One of the highly desired enhancements to the Mars Exploration Rover (MER) and Phoenix flight missions was the centralized coordinate transform database maintained onboard. Without the database, there are quite a few operations that require cumbersome, error-prone manual calculations on the ground such as...

A software framework on top of Hadoop Streaming enables both the processing of binary data in the cloud, and the freedom for the developer to implement his or her mapper and reducer programs in any language, rather than re-implementing existing solutions in Java, or...

Success in mission operations relies on achieving consensus amongst a wide variety of personnel with diverse backgrounds and education. Previously, NASA missions relied on disparate tools with a variety of inconsistent interfaces. These tools greatly influence how members of the mission communicate with each other, increasing confusion and...

Using advanced computers and a computational technique to simulate physical processes at the atomic level, researchers at Brown University have predicted that a material made from hafnium, nitrogen, and carbon would have the highest known melting point: 4,400 kelvins (7,460 degrees...

Originating as the Aerodynamics Division Software Library of the 1980s and -90s, this software is a collection of more than 100 software applications, many of them for manipulating the grids and flow solutions associated with computational fluid dynamics (CFD). Underlying these applications are about 30 libraries...

FIAT v3 simulates one-dimensional thermal energy transport through a multilayer stack of thermal protection materials, bonding materials, metallic or composite structures, air gaps, and/or insulations. The outer surface encounters aerothermal heating from hypersonic flow, and...

An integrated ground support equipment (GSE) tracking and management tool is designed for tracking and managing GSE data used in support of KSC/Ground Systems Development and Operations (GSDO) planning and launch campaigns. This software (the Ground Hardware Management Tool, GHMT) will be fully...

BAT is a Web-based application used for the assembly and inspection of critical flight and associated ground support hardware for JPL missions that are developed in-house. It is used to capture and communicate data that is unique to a part or assembly that cannot be captured...
