Program Determines When MRO Observations Span More Than One Spacecraft Sequencing Period

NASA’s Jet Propulsion Laboratory, Pasadena, California Previously, the Mars Reconnaissance Orbiter (MRO) did not allow observations to go beyond the end of a planning period. However, opportunities for observing the Mars Science Laboratory (MSL) rover occur close enough to these boundaries to require the observations that support the rover to cross these boundaries. This requires the observation to be included in two planning cycles.

Integrated Ground Supported Systems Equation Processor

Goddard Space Flight Center, Greenbelt, Maryland The Integrated Science Instrument Module (ISIM) Ground Support System (IGSS) Equation Processor (IEP) allows for the general production of “derived” telemetry products in the Raytheon Eclipse ground system used to support the James Webb Space Telescope (JWST) project. The IEP works alongside the Raytheon-provided equation-processing system but provides for support of string data types that the existing equation processing does not support. The string data type production is required to support the manipulation of JWST string telemetry data types, and for the production of string data types to produce readable time conversions from a binary value to year, day, hour, minute, second format that can be directly viewed on real-time telemetry display pages. The user writes equation scripts using the Tool Command Language (TCL) and specifies as part of the definition how the equation is triggered and what the results should look like. The TCL scripting language provides for a fully featured programming language to manipulate the string data in any form imaginable.

Perilog

Ames Research Center, Moffett Field, California Perilog measures the degree of contextual association of large numbers of term pairs in text to produce network models that capture the structure of the text and, by virtue of Perilog’s validated theory of iconicity, the structure of the domains, situations, and concerns expressed by the author of the text. Given alphanumeric representations of any other sequences in which context is meaningful — such as music or generic sequences — Perilog can derive their contextual structure.

Build, Assemble, Test (BAT) Planning and Execution Resources Application

NASA’s Jet Propulsion Laboratory, Pasadena, California 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 in an engineering drawing or a test procedure. It includes a list of parts and tools, along with specific steps required for building and assembling a piece of hardware.

Symbolic Techniques for Model Code Optimization: FMI Applications

Since its inception, the FMI standard has become the primary method for model transfer and co-simulation, providing a smooth, error-free technique for design engineers to deliver their work without manual integration or resorting to other proprietary tools. At the same time, advanced symbolic technologies have emerged that provide extremely fast auto-generated code for the implementation of dynamic system models and enable advanced analysis applications. This paper describes symbolic techniques employed under the hood for dynamic system model formulation and optimized code generation. One application where the FMI standard has been used is for generating a functional mockup of an automatic transmission from MapleSim, and implementing it in dSPACE's SCALEXIO to perform a full-vehicle, real-time simulation.
