COTS implementation of a Sensor Planning Service GetFeasibility operation - Interim status

摘要

This paper reports on the progress of the design and implementation of a Web-based Sensor Planning Service (SPS) that discovers sensors, formulates sensor collection tasks, and determines feasibility of collection tasks for optical and radar Earth imaging spacecraft. The design is founded on Commercial off the Shelf (COTS) mission modeling capabilities from Analytical Graphics, Inc. (AGI). An SPS providing a COTS GetFeasibility operation will make it easier for users to discover sensors that fulfill their needs. A COTS common interface will provide the user with one well-known set of operations for the initial discovery of candidate sensors. A final selection of sensors can be carried out using the SPS operations of the individual Data Providers. The first step is a Proof of Concept Sensor-Planning Service (PoC-SPS). It includes the design and implementation of a Standard Object Catalog (SOC) and the design and prototyping of the work flow. The work flow prototyping also supports the design of an interface between system modeling language (SysML) system modeling and AGI mission modeling capabilities. The SOC is a community driven library of spacecraft, facilities and other assets with accurate and thorough descriptions of mission capabilities. The SOC is initially populated with optical and radar Earth imaging spacecraft and sensors.
