A computer program facilitates the analysis and design of a radio-communication system for transmitting data from an orbiting spacecraft to ground stations. Input data provided by the user include primarily (1) parameters of the spacecraft orbit (including parameters that specify...

The Space Communications Protocol Standards (SCPS) specify a developmental system of international protocols for data communications between spacecraft and points on Earth. SCPS protocols are intended to make a spacecraft appear, to a terrestrial computer user, as just another node on...

The Knowledge Server Tools (KST) computer program comprises a distributed set of software tools for monitoring remote systems. Part of KST implements a knowledge server for monitoring the status of a remote system (e.g., a computer-controlled instrumentation system, a robot, or a...

The Monocoque Tank Analysis Spreadsheet System (MONTASS) computer program is an integrated software system that incorporates Microsoft Excel worksheet software and Visual BASIC software. MONTASS was developed to enable rapid analysis and preliminary design of structural domes and...

A software system generates sequences of commands for the operation of a robotic vehicle. The system was adapted to control Rocky 7, a semiautonomous instrumented vehicle of the "rover" type used in scientific exploration of Mars. The software system was developed by integrating two software...

Since it was developed in the late 1980s, the Automated Fatigue Calculation Program (FATPLUS) has consistently demonstrated its ability to predict fatigue life, independently validate proprietary fatigue methodologies, identify fatigue-sensitive parts, and train engineers in predicting...

Three innovative computer programs for training and testing personnel at Kennedy Space Center have been developed under the aegis of the Web Interactive Training (WIT) project. The WIT project exploits the capabilities afforded by the Internet and by state-of-the-art multimedia data-presentation...

The Materials Science Division (MSD) at Kennedy Space Center is developing a computer system to maintain a material-science data base coupled with a user-friendly interface on the World Wide Web. The system is designed to eliminate the need for time-consuming and expensive distribution of,...

Never before have secondary schools been able to post-process raw satellite data, and now they can do it in real time. This is credited to advances in technology that have recently made the necessary equipment simple, inexpensive, powerful, and available enough for any school to fit into...

Four computer programs enable the nearly real-time distribution, analysis, and display of data on temperature, relative humidity, and particle fallout measured by sensors in the Orbiter Processing Facility (OPF) and the Launch Pad Payload Changeout Room (PCR) at Kennedy Space Center. The...

A software library has been developed for adaptive refinement of unstructured (that is, irregular) tetrahedral or triangular meshes that define two- or three-dimensional coordinates or volume elements used in parallel (that is, multiprocessor) finite-element or finite-volume computations. This...

A software library has been developed for use in parallel adaptive refinement of unstructured (irregular) meshes and grids in parallel scientific and engineering computing. This library can be used in finite-difference, finite-volume, and finite-element application programs that use...

A report discusses the development of a highly complex system of distributed-computing, multidisciplinary design-optimization software, called "CJOpt," for use in research on model 4 of the High-Speed Civil Transport (HSCT) airplane (HSCT4.0). The emphasis in the report is on the...

The Horizons On-Line Ephemeris and Data System ("Horizons" for short) is a computer program that provides data on the locations, motions, and dynamical parameters of solar-system objects, including the Sun, nine planets, 61 natural satellites, more than 16,000 comets and asteroids, and...

A software system for planning and execution of actions by an autonomous spacecraft engaged in scientific exploration has been developed to satisfy requirements to (1) maintain positive resource margins and avoid short-sighted decisions in order to achieve long-term scientific and...

A computer program provides for automated generation of maps from data acquired via C-band interferometric synthetic-aperture radar (IFSAR). The program reads in height, radar-brightness, and correlation data generated by IFSAR processors and computes a series of image features to be used in classifying...

Millimeter-Wave Optics Design Tool (MOD Tool) is a computer program for analyzing and designing multiple-reflector antenna systems that operate at microwave and millimeter wavelengths. MOD Tool is intended for use in conjunction with a computer-aided-design (CAD) program along with other...

Version 1.4 of the Launch Vehicle Loads Analysis for Preliminary Design (VLOADS 1.4) computer program calculates in-flight launch-vehicle structural loads (that is, spacecraft-launching rockets) for preliminary design. The program can also be used to calculate structural loads in upper stages and...

The Automated Test Monitor computer program provides for continuous monitoring of the operations of a complex system (e.g., a spacecraft). This program implements a rigorous analytic (instead of an ad hoc) technique that prescribes exactly how to express requirements for the operation of...

"Planning and Resource Reasoning" ("PARR") is the name now applied to a scheduling methodology and to computer programs developed to implement the methodology during the years 1985 through 1987. In PARR, one uses heuristics and reactive techniques to build schedules. PARR software is generic enough to be...

A computer-based automated system for scheduling, reporting, and tracking fire inspections at Kennedy Space Center has supplanted a manual system based on paper fire-inspection reports transmitted by mail. The automated system not only minimizes the consumption of paper and other resources but...
