Multi-Spacecraft Attitude and Trajectory Simulation (42)GSC-14817-1Written in ANSI C to maximize portability and customization capacity, “42” provides a simulation of theattitude and translational dynamics of multiple spacecraft that could be operating anywhere in the solarsystem. Attitude dynamics feature high-fidelity models of spacecraft composed of up to three connectedrigid bodies, each with up to four embedded momentum wheels. Translational dynamics use Encke’smethod of orbit perturbation and are formulated to preserve the numerical accuracy required for precisionmulti-spacecraft formations.U.S. Government Purpose ReleaseNavigation Accuracy Guidelines for Orbital Formation FlyingGSC-15096-1Based on the accuracy of determining a satellite formation’s semi-major axis differences, these simpleguidelines could be useful in the preliminary design process and are valid for any elliptical orbit regardlessof eccentricity.U.S. Government Purpose ReleaseOrbit-Determination ToolboxGSC-15728-1Based on MATLAB and Java, the flexible Orbit-Determination Toolbox is intended primarily for the advancedmission analysis that might be performed in the concept exploration, proposal, and early design phases.Visit the following URL for more information: Open SourceParallel Dantzig-Wolfe DecompositionARC-16432-1This implementation of the Dantzig-Wolfe decomposition is built upon the GNU Linear Programming Kit.The technology provides a command-line tool for solving properly decomposed linear programs.

AeronauticsStochastic Terminal Area Scheduling Simulation (STASS)ARC-17079-1STASS simulates air traffic in the terminal area and ground traffic on the terminal surface. The technologyuses time-based queues at various locations along an aircraft’s trajectory to model traffic. For arrivals,queue locations include the freeze horizon, metering fixes, and runways. For departures, queues are positionedat airport gates, runways, and metering fixes. Flight time uncertainty is modeled using probabilitydistributions around queue arrival times.U.S. Government Purpose Release152NASA Technology Transfer Program Software Catalog 2014
