JPSS replaces the current Polar-orbiting Operational Environmental Satellites (POES) managed by NOAA in the 1330 local time of ascending node (LTAN) orbit. The Defense Meteorological Satellite Program (DMSP) managed by the DoD is operating in the 1730 LTAN orbit. The DoD is developing a follow-on system for DMSP which will continue in the 1730 orbit.
The Suomi National Polar-orbiting Partnership (NPP) satellite serves as a pathfinder for and provides continuity for the NASA Earth Observation System and the POES with its launch on 28 October 2011. NPP and the follow-on JPSS satellites will operate in the 1330 LTAN orbit and are being developed by NASA. JPSS-1 is scheduled to launch in late 2016. NASA is developing the Common Ground System to process both the JPSS and the DoD follow-on constellations.
This poster will provide a top level status update of the program, as well as an overview of the JPSS system architecture. The space segment carries a suite of sensors that collect meteorological, oceanographic, and climatological observations of the earth and atmosphere. The system design allows centralized mission management and delivers high quality environmental products to military, civil and scientific users through a Command, Control, and Communication Segment (C3S). The data processing for NPP/JPSS is accomplished through an Interface Data Processing Segment (IDPS)/Field Terminal Segment (FTS) that processes NPP/JPSS satellite data to provide environmental data products to NOAA and DoD processing centers as well as remote terminal users. The IDPS will also serve the DMSP follow-on program as the Common Ground System, providing the ground processing for the JPSS and DoD Satellites in the future.
