NPOESS: Converging Civil and Defense Satellite Capabilities

This document discusses the capabilities and requirements of the National Polar-orbiting Operational Environmental Satellite System (NPOESS), which aims to improve global coverage and long-term continuity of observations at a lower cost. It provides information on existing polar-orbiting systems, future plans for NPOESS, and the payloads and instruments involved. The document also highlights the importance of international cooperation and enhancements in the Argos instrument.
