COTS implementation of a Sensor Planning Service GetFeasibility operation — Final status

This paper reports on the progress of the design and implementation of a Web-based Sensor Planning Service (SPS) that provides GetCapabilities, DescribeTasking, and GetFeasibility operations for optical and radar Earth imaging satellites. The design is founded on Analytical Graphics COTS capabilities and Standard Object Catalog (SOC). The SOC is a community-driven library of satellites with accurate and thorough descriptions of mission capabilities. Each SOC entry consists of a searchable description and an AGI Systems Tool Kit (STK) object modeling the satellite and its imaging payloads. Aspects of two designs have been prototyped and evaluated. The first design is based on the architecture prescribed by the Open Geospatial Consortium (OGC®) Sensor Web Enablement (SWE) initiative in which the User exchaneges XML documents with the SPS. The second design has the SPS providing its functionality througth a web-based interface, freeing the User from the XML-document and message exchange paradigm.
