TIGRAS 2.0 is a computer program designed to satisfy a need for improved means for analyzing the tracking demands of interplanetary space-flight missions upon the set of ground antenna resources of the Deep Space Network (DSN) and for allocating those resources. Written in Microsoft Visual C++, TIGRAS 2.0 provides a single rich graphical analysis environment for use by diverse DSN personnel, by connecting to various data sources (relational databases or files) based on the stages of the analyses being performed. Notable among the algorithms implemented by TIGRAS 2.0 are a DSN antenna-load-forecasting algorithm and a conflict-aware DSN schedule-generating algorithm. Computers running TIGRAS 2.0 can also be connected using SOAP/XML to a Web services server that provides analysis services via the World Wide Web. TIGRAS 2.0 supports multiple windows and multiple panes in each window for users to view and use information, all in the same environment, to eliminate repeated switching among various application programs and Web pages. TIGRAS 2.0 enables the use of multiple windows for various requirements, trajectory-based time intervals during which spacecraft are viewable, ground resources, forecasts, and schedules. Each window includes a time navigation pane, a selection pane, a graphical display pane, a list pane, and a statistics pane.

Overview
The document presents an overview of TIGRAS 2.0, a software program developed by NASA's Jet Propulsion Laboratory (JPL) to enhance the analysis and allocation of tracking resources for interplanetary space missions within the Deep Space Network (DSN). As demand for DSN services grows and new tracking requirements emerge, TIGRAS 2.0 addresses the need for improved resource allocation and scheduling tools.
Written in Microsoft Visual C++ and utilizing Microsoft Foundation Classes (MFC), TIGRAS 2.0 offers a rich graphical analysis environment that integrates various user groups, including RAPSO (Resource Allocation and Planning for Space Operations), DSN schedulers, and project teams. The software connects to multiple data sources, such as relational databases and files, facilitating comprehensive analysis based on the specific needs of users.
Key features of TIGRAS 2.0 include its ability to support multiple windows and panes, allowing users to view and manipulate information without the need to switch between different applications. Each window is equipped with a time navigation pane, selection pane, graphical display pane, list pane, and statistics pane. The graphical display can generate various chart types, including Gantt charts, bar charts, XY charts, and circle charts, tailored to the analysis type.
TIGRAS 2.0 incorporates two significant algorithms: a DSN antenna load forecasting algorithm and a conflict-aware schedule generation algorithm. These algorithms work in tandem with the graphical environment to provide users with effective decision support and operational capabilities. The software also supports drag-and-drop functionality for schedule editing within a conflict-aware Gantt chart display, distinguishing it from traditional conflict-free Gantt charts.
Additionally, TIGRAS 2.0 connects to a .NET Web service server via SOAP/XML for selected computational tasks and includes features for offline access to local archive data. It also integrates with Microsoft Excel for reporting purposes, enhancing its utility for users.
The document emphasizes that TIGRAS 2.0 is available for commercial licensing and provides contact information for inquiries. Overall, TIGRAS 2.0 represents a significant advancement in resource management for NASA's DSN, enabling more efficient tracking and scheduling for interplanetary missions.
