Data Acquisition Software

HBM, Marlborough, MA, has released Version 6.60 of its Perception software for high-speed data acquisition applications. The software is designed for processing large amounts of data — 100 GB within 10 seconds. The software’s “eDrive” application lets users make measurements on electric inverters and drive systems, and visualize torque and rotational speed as live curves. Users can create individual “workbenches” that can be defined with distinct restrictions, test functions, and capabilities. For Free Info Visit http://info.hotims.com/61059-104

Vehicle Communication Simulation

With Release 2015-B, dSPACE, Wixom, MI, has launched the V2X Solution through a dedicated blockset directly within the Simulink® environment. The V2X solution gives users access to Vehicle-to-X (V2X) WLAN ad-hoc communication during model-in-the-loop (MIL), software- in-the-loop (SIL), and hardware- in-the-loop (HIL) simulation. A map instrument displays a vehicle’s position, velocity, driving direction, and classification of individual traffic participants as well as other V2X-specific information.

Full-Wave Matching Circuit Optimization Shortens Design Iterations

Full-wave matching circuit optimization (FW-MCO) is a new technology introduced by Remcom, which combines full wave 3D EM simulation and circuit optimization to solve an age-old RF problem:determining which component values provide the desired match for a given matching network layout.

Advanced Numerical Integration Techniques for High-Fidelity SDE Spacecraft Simulation

Goddard Space Flight Center, Greenbelt, Maryland Simulation study is an integral part of the validation of navigation algorithms for spacecraft. While it is possible to come up with an estimate of a navigation algorithm’s performance with a low-fidelity system model, the mathematical analysis is intractable for higher-fidelity models that include fuel slosh, flexible booms, sensor saturation, etc. Thus simulation study is a vital step in validating navigation algorithms before an actual satellite is launched.

Launch Environment Water Flow Simulations Using Smoothed Particle Hydrodynamics

This method has been used in applications involving ocean modeling, volcanic lava, sloshing, and fuel pumps. John F. Kennedy Space Center, Florida One of the crucial ground structures employed at the launch pad during the Space Shuttle program is the rainbird nozzle system, whose primary objective is to suppress acoustic energy generated by the launch vehicle during pad abort and nominal operations. It is important that the rainbird water flow does not impinge on the rocket nozzles and other sensitive ground support elements. For the new Space Launch System (SLS) vehicle, the operation is similar, regardless of the new mobile launcher and new engine configurations. The goal of the rainbird nozzle system remains sound suppression (SS), and the rocket engines still cannot get wet. However, the rearrangement of the rainbird water system for the SLS mobile launcher locates the rainbirds closer to the first-stage rocket engines, which are positioned above the exhaust hole. The close proximity of the rainbird nozzle system could potentially cause vehicle wetting during liftoff.

Seismometer Simulation Software

NASA’s Jet Propulsion Laboratory, Pasadena, California Seismometer Simulation Software (SEISim) is written to provide a simulation for the seismometer instrument in the Insight (Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport) mission so that flight software developers can use it to develop and test their software applications. It can generate science data packets, generate housekeeping data packets, and simulate certain instrument behaviors such as leveling, re-centering, and calibration. It has fault injection capabilities that allow flight software developers to inject faults through SEISim to test their software in various scenarios. It also allows users to run multiple instances of SEISim for batch and overnight testing.
