Techniques and trends in sensor data processing: NASA experiences with Earth observing satellites

摘要

NASA's Earth Science Mission Operations and Systems (ESMOS) Project is responsible for developing and operating sensor data capture, processing and delivery systems on behalf of NASA's Earth Science Enterprise (ESE). As the volume of sensor data being collected by the next generation of Earth observing satellites continues to dramatically increase, the demand for timely data delivery has correspondingly increased. The ESMOS Project has utilized a variety of techniques and methodologies to provide sensor data to the end user, and has collected a series of lessons learned with regard to the most efficient implementations based on the needs of the end user. This paper discusses the successes achieved and the pitfalls encountered by NASA, NOAA and ESA and makes recommendations for changes and enhancements to maximize future mission sensor data processing.
