The autonomous self-healing (eDNA) hardware platform is a reconfigurable field-programmable gate-array (FPGA)-type platform developed by Technical University of Denmark (patent: WO/2010/060923). It is capable of autonomously reconfiguring itself in case a fault is detected...

GPS receivers must compensate for the delay a GPS signal experiences as it passes through the ionosphere in order to accurately determine the position of the receiver. Receivers limited to terrestrial operation may utilize the Klobuchar parameters transmitted by...

Wafer-level integration was employed to mount the microshutter array for the James Webb Space Telescope (JWST) and the detector-read-out hybrid for TIRS (Thermal Infrared Sensor). In the case of the JWST substrate, two conductors (polysilicon and aluminum) separated by a silicon oxide...

A concept was developed for a multi-gigabit-rate, radiation-hardened (RH) bus that would support open-system architecture and provide a cost-effective, high-speed interconnect. This concept is based on Advanced Science and Novel Technology Company’s SerDes system, which supports a variety of interfaces, and...

As a result of performing IV&V (Independent Verification and Validation) on Space Station software, a number of interface faults were found during integrated testing or actual software deployment. Faults found at this late phase of the software development lifecycle are very expensive to...

Simple, Scalable, Script-based, Science Processing (S4P) Archive (S4PA) is a disk-based data-archiving system for remote sensing data. It is based on the data-driven framework of S4P. The system is used for new data transfer, data preprocessing, metadata generation, and data archival. The...

The Planetary Data System (PDS) has undertaken an effort to overhaul the PDS data architecture (e.g., data model, data structures, data dictionary, etc.) and deploy a software system (online data services, distributed data catalog, etc.) that fully embraces the PDS federation as an integrated...

ZONE (Zeroing Out Negative Effects) is a method of biofeedback training for optimal athletic performance. ZONE is designed to improve athletes’ responses to stress, anxiety, and loss of concentration during competition. In the training environment, when the user successfully attains an optimal...

In high-integrity systems, a method of assuring integrity called a self-checking pair is employed. A self-checking pair is a logical grouping of two of the same devices performing the same operation and cross-checking each other to ensure correct operation. In this manner, a...

The system and method of reconfigurable Auditory-Visual Display creates a multi-mode communications environment with the express intent of increasing situational awareness for the operator (controller), and for reducing operator fatigue. Situational awareness is increased by a...

Short block codes are in demand by international space agencies for transmission of command and control data to spacecraft in the uplink channel. Codes that outperform currently used binary codes with the same block lengths and code rates are desirable. A design method constructs...

A method has been developed for resolving algebraic loops that occur in closed-loop systems when using MathWorks Simulink modeling and simulation tools. This variable fidelity method improves accuracy and reduces runtime significantly for users of Simulink Coder...

A 3D finite element mathematical model has been developed for representing a behavior of a magnetic mirror and nano antenna subject to polarized incident light. This model represents the fourth generation of magnetic mirror with the goal of suppressing the diffraction.

A high-fidelity numerical simulation software (CRUNCH CFD®) predicts the transient performance of flight valve designs, provides design support by supplementing current empirical rules, and diagnoses system anomalies. Currently, transient analysis of valves is...

In this innovation, a method makes use of a new technique for describing analog information based on the roots of polynomial functions of infinite degree. Monotonic analog signals are transformed into characters that are fused into a two-dimensional composite visualization of the generating signal...

A fast Fourier transform (FFT) was developed as part of the Soil-Moisture Active/Passive (SMAP) project. The FFT was created on 16-bit data arriving at a rate of 48 MHz to run on a resource-constrained, space-grade field programmable gate array (FPGA).

An Integrated Modular Avionics (IMA) architecture provides a common platform for software partitions with shared processing and input/output (I/O) resources. A key feature of the IMA architecture is I/O partitioning. An IMA system will prevent one...

Smart sensors for measuring temperature and pressure have been developed as part of the Advanced Ground Systems Maintenance (AGSM) project. The sensors have flash memory for storing firmware, calibration data, and configuration information....
