Government Resource for Algorithm Verification, Independent Test, and Evaluation (GRAVITE) system is a National Oceanic and Atmospheric Administration (NOAA) system, developed and deployed by Joint Polar Satellite System (JPSS) Ground Project to support Calibration and Validation (Cal/Val), Data Quality Monitoring, and Algorithm Investigation, Tuning and Integration. GRAVITE enables novice and expert users to discover and obtain data easily by using standard protocols. GRAVITE version 3.0 (GV3.0) distribution system is a major upgrade to the GRAVITE version 2.0 (GV2.0) distribution tools. GV2.0 enabled users to easily define dynamic searches, which unfortunately resulted in slowing down the operational database, as no back-end validation was performed.
The Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) is an Earth imaging radar that flies on a Gulf-Stream Jet. Its mission is to collect data for NASA scientists who are using Synthetic Aperture Radar to develop methods for monitoring changes in the Earth’s surface. As with many other technologies, there is always the possibility of technological or human errors. Since smartphones are mobile, common, and powerful devices, they can be used to reduce the possibility of operator error when the radar is being configured for flight.
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.
Worldview is a software tool designed for interactively browsing and downloading imagery from NASA’s Earth observing satellites. Building upon a set of open source mapping and user interface libraries, it provides an environment to visually discover interesting phenomena as observed by NASA satellites, then download the data for further analysis. It was originally designed to address the needs of the near-real-time applications community to provide relevant information for time-critical scenarios such as wildfire and flood management. As such, satellite imagery is available to be viewed in Worldview within four hours of observation; the imagery can be viewed in its highest, or native, resolution, and the imagery can be panned and zoomed rapidly through space and time to find the most relevant/cloud-free information available.
Several software application development tools exist that enable the rapid development of Web applications. Among other things, Web applications greatly enhance the human-computer interaction (HCI) required by many systems, while simplifying the problem of deploying applications to customers. Capitalizing on the new features provided by these tools could prove to be a boon to mission and project teams.
SW DONKI is a comprehensive Web application for space weather forecasters, scientists, and the general space weather community. It serves as an archive for space weather activities including solar flares, coronal mass ejections (CMEs), solar energetic particles, and geomagnetic storms. An innovative feature of the system is the ability to generate, modify, and store complex linkages between space weather events — creating a comprehensive network of relationships between activities, and identifying potential cause-and-effect paradigms for each space weather event. SW DONKI also provides public access to all human-generated event analysis and notifications produced by the Space Weather Research Center (SWRC) forecasting team at CCMC (Community Coordinated Modeling Center).
A series of scripts stitch together existing open-source Python modules for the purpose of displaying, cleaning, and measuring photometric properties within public Kepler data. The intent of these tools is to provide convenience to the Kepler science community, and to increase cost efficiency for the project. With 500+ users in the community, an open-source development provides the best resource for sharing tools, while minimizing cost and duplicated effort.
The Automated Evaluation Software Web application was created using Java Enterprise technologies, which provided capabilities for dynamic report generation and Microsoft output. The Tomcat Application server makes the application robust, fast, and reliable. HTML 4.0 was used to create the user interface, making it compatible with both Internet Explorer and Firefox. The application takes advantage of the Jakarta Struts framework, making a proper Model View Controller design. The Struts framework provides the ability to change the navigation and presentation without changing the underlying data model, and vice versa.
In the not too distant “Internet of Things” reality, sensors could be embedded in everyday objects to help monitor and track everything from the safety of bridges to the health of your heart. But what’s holding this new reality back is having a way to inexpensively power and connect these devices to the Internet, say engineers at the University of Washington, Seattle.
