The Suomi National Polar-orbiting Partnership (S-NPP) and Joint Polar Satellite System (JPSS) satellites include a High-Rate Data (HRD) antenna that continuously downlinks sensed data as it is collected. Such a downlink is often referred to as a Direct Broadcast (DB). The JPSS Ground Project Field Terminal Support (FTS) node has been developed and implemented, providing FTS fundamental processing “building blocks” (software components, data and documentation) using a public web portal. This includes Mission Support Data (including ancillary data, auxiliary data and Mission Notices) and the necessary hardware and software specifications needed for processing the broadcasts. Orbital data is also provided on the FTS web portal, to assist the DB community in locating the satellites of interest. With their own equipment (a local antenna and a remote terminal) and the above provided information, the DB community can capture and process the HRD content and generate data products, such as Raw Data Records (RDRs), Sensor Data Records (SDRs) and a subset of Environmental Data Records (EDRs). The JPSS Ground System maintains equipment at the Svalbard Ground Station, which monitors the quality of the direct broadcast link and generates an HRD Link Monitoring (HLM) report. This report is also available on the FTS web portal.
The FTS Portal is now operational. Access to the FTS web portal is through a self-registration process and all customers around the world will be granted access. To access the FTS web portal please go to: https://fts.jpss.noaa.gov.
The JPSS Program also supports the NASA GSFC Direct Readout Laboratory (DRL) and the University of Wisconsin Cooperative Institute for Meteorological Satellite Studies (CIMSS) (hereafter referred to as the algorithm Integrators). The Integrators have developed user-friendly software processing systems (DRL: the International Polar-Orbiter Processing Package (IPOPP), and CIMSS: the Community Satellite Processing Package (CSPP)) that enable the DB community to easily integrate the algorithms into their remote terminals. The Integrators have antennas to acquire and process the downlink data to ensure the quality of the fundamental processing building blocks and their developed software processing packages.
Each of the Integrators have web-portals to interact with and to serve the DB community.
