Technical Session II: Advanced Operations Concepts
Abstract
The Java-based spacecraft web interface to telemetry and command handling, Jswitch, is a prototype, platform-independent user interface to a spacecraft command and control system that uses Java technology, readily available security software, standard World Wide Web protocols, and commercial off-the-shelf (COTS) products. The Java-based science analysis and trending tool, Jsat, is a major element in Jswitch. Jsat is an inexpensive, Web-based, information-on-demand science data trend analysis tool. Both Jswitch and Jsat were developed in Java for NASA's Goddard Space Flight Center (GSFC). Jsat provides Web interface user access to science data from different satellites. Historically, satellite science data trend analysis has been an additional time-consuming operational consideration in which logistics of the science analytical parameter requests/responses are cumbersome and restrictive. Jsat removes this middle layer of access by sending the processed science satellite data (userspecified graphics, tables, and reports) as Java applets via the Web to the user upon request. Jsat reduces ground science data processing costs and decreases processing time by eliminating the need for special operations personnel assigned to process science data requests, run trend analysis software, and collect and distribute results. Jswitch reduces operational costs by providing access to spacecraft telemetry and command from any standard web browser.
