Satellite Programme: Joint Polar Satellite System
Programme details
Programme description
Four-satellite programme following a precursor (SNPP), resulting from restructuring the National Polar-orbiting Operational Environmental Satellite System (NPOESS). NPOESS was being defined as a dual-use civilian-military undertaking of NOAA and DoD. In 2010, it was split into a civilian component (JPSS) and a post-DMSP programme formerly named DWSS (Defence Weather Satellite System).
Part of the instrumentation is flown as free-flyers, called SIDAR (Solar Irradiance, Data and Rescue).
USA programme. Responsible agency: NOAA, with initial developmental role of NASA.
3-axis stabilised platform.
The design life time of the satellites is 7 years (5 years for SNPP).
The satellites exploit a sunsynchronous orbit around 13:30 to provide continuity to the last flight units of the POES series.
The replacement policy is based on launching satellites at roughly 5-year intervals.

Data circulation
CDA (Command & Data Acquisition station) to acquire Stored Mission Data (SMD). Main locations: Svalbard (Norway) and Fairbanks (Alaska).
HRD (High Rate Data) for real-time broadcasting of full-resolution data.
LRD (Low Rate Data) for real-time broadcasting of selected data (starting with JPSS-2).
