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

2. Getting Ready for JPSS

3. 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

5. 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

6. 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

7. 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

9. 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)
DRL: International Polar-Orbiter Processing Package (IPOPP)
The software integrators interact with and serve the DB community with web portals that they have independently established.

11. International Polar Orbiter Processing Package

12. 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 A), 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
