Direct Broadcast Receive Station -- The antenna tracks the satellite, the signal is down
converted and input to the QPSK receiver/demodulator where the signal is demodulated and
data streams are created. The field terminal software ingests the data and generates data
products. Many HRD users utilize the CSPP software.
For the JPSS mission, the HRD direct broadcast is a continuous downlink of mission environmental
data to users on the ground that are equipped with the resources necessary to capture the
broadcast when the satellite is within view. The objective of the HRD content is to include the
full set of science and calibration data from the mission instruments, as well as the spacecraft
attitude and ephemeris data necessary for data product generation, in order to meet the needs of
the direct broadcast community.
The data rate is 15 Mbps (7812 MHz) for SNPP and NOAA-20. However, the data rate for NOAA-21
(JPSS-2/3/4) and beyond will increase to 25 Mbps.
The science data on the HRD includes data from: Cross-track Infrared Sounder (CrIS), Advanced
Technology Microwave Sounder (ATMS), Visible Infrared Imaging Radiometer Suite (VIIRS),
Ozone Mapping and Profiler Suite (OMPS), Clouds and the Earth's Radiant Energy System (CERES)
(S-NPP and NOAA-20 only).
There are 47 HRD users. Many HRD users utilize the Community Satellite Processing Package
(CCSPP) Low Earth Orbiting (LEO) software to ingest the HRD science data and create data
products (from CrIS, ATMS, and VIIRS).
The JPSS Program posted the Joint Polar Satellite System-2 (JPSS-2) Satellite High-Rate Data
(HRD) to Direct Broadcast Stations (DBS) Radio Frequency (RF) Interface Control Document (ICD)
on the JPSS Website. The ICD applies to JPSS-3 and JPSS-4 as well:

HRD users can join the NOAA-led HRD User Group. The HRD User Group
encourages collaboration among users, facilitates information flow
among NOAA and users, and helps OSPO measure user satisfaction with
the HRD. The Chairman of the HRD User Group updates the number of
HRD stations, current and planned sites, and locations of HRD sites
every three months, if you need additional information, you can
contact
Toby Hutchings.
All Direct Readout (DRO) and Direct Broadcast (DB) users can
complete the
DRO Survey.
