The National Polar-orbiting Operational Environmental Satellite System future US operational Earth observation system

摘要

Over the last nine years the Integrated Program Office has been developing the National Polar-orbiting Operational Environmental Satellite System (NPOESS). NPOESS spacecraft will be launched into three orbital planes beginning later this decade to provide significantly improved operational capabilities and benefits to satisfy the critical civil and national security requirements for space-based, remotely sensed environmental data.
