Off-the-Shelf Real-Time Monitoring of Satellite Constallations in a visual 3-D Environment Ursula Schwuttke NASA/JPL Co-authors: Robert Angelino robert@puente.jpl.nasa.gov Anthony Mactutis Alan Quan NASA/JPL Abstract: The Multimission Spacecraft Analysis System (MSAS) Data Monitor is a generic software product that represents the next-generation in real-time data monitoring and analysis tools. It goes beyond conventional text-based displays by representing data in a unique graphical form, conveying system status through the shape, color, motion, and position of graphical objects floating in a three-dimensional cyberspace environment. It is ideal for monitoring high volumes of data, for viewing results in easily configurable displays, and for providing both high-level and detailed views into a constellation of monitored satellites. The Data Monitor offers a great improvement over conventional graphic and text-based displays, not only because it dramatically increases the amount of data that a single person can absorb in limited time, but also because it can be completely installed and configured without any software development by the end-user. The system also provides innovation in alarm detection, reporting of both traditional limit-based alarms and alarms triggered by automated analysis of data.
