The United States National Polar-orbiting Operational Environmental Satellite System (NPOESS) will provide Earth
observations in both X-band and L-band direct broadcasts (DB) to the global direct readout (DRO) community.
NPOESS capabilities provide the Oceanic regions of the world with the ability to assess their regional environments
from space in near-real time by providing DRO capabilities for 41 HRD environmental data records (EDRs) to include
imagery, and relays from ARGOS Advanced Data Collection System
(A-DCS) sensor. Additionally, NPOESS provides
within the direct broadcast links dynamic mission support data (MSD) which updates more quickly than can be
accommodated through thrice annual software releases. MSD included within the links include weather forecast model
parameters and algorithm processing coefficients. The NPOESS data processing software will be made available free of
charge2 to the global community. Thus the NPOESS DRO mission will allow regional oceanic communities to compile
knowledge of their local environments by having an up to date understanding of developing weather systems for disaster
monitoring, an understanding of land and ocean environmental trends, and in-situ measurement retrieval from A-DCS
sensors. This information interpreted and understood by experts of the region allows for significant contributions to the
Earth Observation System of Systems (GEOSS) goals and mission that are not otherwise possible within the large
oceanic community with limited communication resources.
Preparing for the next generation polar orbiting environmental satellite system, the NPOESS system is currently undergoing the design phase of the Program. The NPOESS Direct Readout Mission will service users in the field providing regional environmental coverage with two direct broadcast links, high rate data (HRD) at 20 Mbps and low rate data (LRD) at 3.88 Mbps. Contained within these two links are the suite of sensor data in order to generate 50 HRD and 29 LRD weather products via the NPOESS Field Terminal Segment software being developed for distribution to the weather community or by value added resellers.
