ION is a system of ground support software for the ion and neutral mass spectrometer (INMS) instrument aboard the Cassini spacecraft. By incorporating commercial off-the-shelf database, Web server, and Java application components, ION offers considerably more ground-support-service capability than was available previously. A member of the team that operates the INMS or a scientist who uses the data collected by the INMS can gain access to most of the services provided by ION via a standard point-and click hyperlink interface generated by almost any Web-browser program running in almost any operating system on almost any computer. Data are stored in one central location in a relational database in a non-proprietary format, are accessible in many combinations and formats, and can be combined with data from other instruments and space-craft. The use of the Java programming language as a system-interface language offers numerous capabilities for object-oriented programming and for making the database accessible to participants using a variety of computer hard-ware and software.

Overview
The document outlines the development and functionalities of ground support software for spaceborne applications, specifically focusing on systems used in NASA's missions, such as the Cassini Plasma Spectrometer (CAPS) and the Ion and Neutral Mass Spectrometer (INMS). It emphasizes the integration of web-based technologies, Java programming, and relational databases to enhance project efficiency, cost-effectiveness, and scientific return.
One of the key systems discussed is the Electronic Cassini Activity Request System (eCARS), which assists science planners in analyzing and ranking science opportunities for the CAPS instrument. This tool streamlines the planning process by allowing scientists to assess various parameters systematically.
The document also details the ION system, which supports science planning through a combination of online coordination, planning, and reference functions. It includes features such as a messaging system for tracking planning issues, a reference area for meeting minutes and schedules, and tools for generating simulated instrument data sets. The Uplink section of ION facilitates the creation of command sets for the instrument, while the Downlink section manages telemetry data, allowing for real-time monitoring and historical review.
Additionally, the analysis section of ION provides scientists with quick-look analysis capabilities, enabling them to index, sort, and filter data sets, as well as generate customized charts and graphs. The state management section automates functions like memory dump comparisons and state predictions, reducing the operational workload and allowing more focus on scientific analysis.
The document highlights the extensive help system integrated into ION, which includes a comprehensive data dictionary, context-sensitive help pages, and a messaging system for user feedback. This support structure enhances user experience and facilitates efficient navigation through the system.
Overall, the document illustrates the collaborative efforts of various individuals and organizations in developing these advanced software systems, showcasing their potential to improve the planning, execution, and analysis of scientific missions in space. The integration of modern technologies not only enhances operational capabilities but also maximizes the scientific return from space missions, paving the way for future advancements in aerospace technology.
