NOAA Transition to New Direct Readout Systems for JPSS Presented to CGMS-44 Working Group 1, agenda item 3.2

Getting Ready for JPSS

Introduction & Key Points This presentation provides to the CGMS community an overview of the JPSS support of Direct Readout Systems. JPSS shall provide the DR community with software, documentation, and periodic updates to enable them to produce data products from JPSS, using their own hardware to receive the JPSS HRD broadcasts. The JPSS Ground Project also supports the University of Wisconsin Cooperative Institute for Meteorological Satellite Studies (CIMSS) and the NASA GSFC Direct Readout Laboratory (DRL integrators) to provide enhanced services via user-friendly software packages. JPSS-1 launch – Spring 2017

Satellite Communication Links Direct Broadcast components indicated in green TDRS SMD Antenna DB Antenna S-Band Antenna Direct Broadcast High Rate Data (HRD) Downlink 8.2125 GHz 300 Mbps TDRSS Ground Link 7.812 GHz 15 Mbps TDRSS White Sands Station Ground Station Svalbard, McMurdo, Fairbanks, Troll Direct Readout User Terminal

Field Terminal Support (FTS) Level 1 Requirements JPSS Level 1 Requirements Document (JPSS L1RD) provides the fundamental requirements and scope of JPSS Field Terminal JPSS-1 and JPSS-2 will provide High Rate Direct Readout (HRD) broadcast X-band, ~15 Mbps downlink JPSS shall provide the DR community with software, documentation, and periodic updates to enable them to produce data products from JPSS, using their own hardware to receive the JPSS HRD broadcasts The JPSS Program is not responsible for developing, testing, or deploying any JPSS capable field terminal JPSS will not perform encryption of the direct broadcast

Key Functions of FTS (1 of 2) Provide the following functionality: Hardware Specifications Suggested field terminal configurations DFCB and RF-ICD Containing specifics on direct broadcast data format Software to produce RDRs from packets Provide and maintain RT-STPS Algorithms & Software Used to create data products from direct broadcast Updated algorithms & software Notification when updates are available Mission Support Data Ancillary/auxiliary data

Key Functions of FTS (2 of 2) Provide the following functionality (cont’d): Maintain list of registered users Condition for NTIA Frequency allocation approval Mission status Users are provided status of the JPSS direct broadcast HRD Link status Users are provided post-pass performance information On-orbit checkout and special tests Gather feedback from FTS community User community prioritization of the HRD link Provide feedback to the Program Promote the use of the JPSS data products from HRD link

Remote Polar Orbiting Data Processing User-friendly software processing systems have been developed that enable the Direct Broadcast community to easily integrate the algorithms into their remote terminals. CIMSS: Community Satellite Processing Package (CSPP) https://cimss.ssec.wisc.edu/cspp/ DRL: International Polar-Orbiter Processing Package (IPOPP) https://directreadout.sci.gsfc.nasa.gov/?id=dspContent&cid=68 The software integrators interact with and serve the DB community with web portals that they have independently established.

Summary There is a paradigm shift in the FTS implementation The JPSS Ground Project is no longer providing data processing framework FTS is providing the necessary building blocks (software, documentation, and mission support data) on the web portal The proposed FTS implementation plan leverages ongoing activities to support needs of DB community and meets all the FTS requirements The proposed FTS implementation will ensure to meet NASA and NOAA Standards, Software Engineering Requirements (NPR 7150.2A), IT Security, and Safety Mission Assurance The JPSS Program is supporting the development and maintenance of software package to demonstrate the ability to produce ready-to-use products from the SNPP/JPSS HRD link The JPSS Ground Project supports the University of Wisconsin Cooperative Institute for Meteorological Satellite Studies (CIMSS) and the NASA GSFC Direct Readout Laboratory (DRL) to provide enhanced services to the user community. FTS will leverage existing annual workshops to provide a forum for the DB community to present, discuss, learn, and provide feedback to the JPSS Program
