• JPSS Level 1 Requirements Document (JPSS L1RD) provides thefundamental requirements and scope of JPSS FTS– JPSS 1 will provide HRD broadcast
– JPSS 2 will provide HRD broadcast
– JPSS 2 will provide Low Rate Data (LRD) broadcasts
– JPSS shall provide the DR community with software, documentation, andperiodic 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, ordeploying any JPSS capable field terminal
• JPSS will not perform encryption of the direct broadcast
FTS Level 1 Requirements
6
• 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 (1 of 2)
7
• 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

Algorithm Development Library (ADL)Centerpiece of FTS Implementation
• JPSS Science Team members heavily relyupon ADL as part of the Algorithm ChangePackage (ACP)
• ADL provide a means for processing RDRsinto SDRs and EDRs
• IPOPP and CSPP currently use ADL in theirHRD processing system
• Most of the direct broadcast users are notfamiliar with using ADL
• JPSS Program will provide the seed moneyfor the development and maintenance ofIPOPP and CSPP

FTS Data Acquisition and Organization
• FTS acquires and organizes data and documentation relevant to HRD processingfrom JPSS managed satellites
• Data is obtained from the CGS, the CGS support node, GRAVITE and JPSS CM, andstored in the Data Acquisition server
• This data includes processing source code (e.g., ADL, algorithm update packages,RT STPS), documentation, ancillary data, intermediate products and auxiliarydata (PCTs, LUTs, Mission Notices, Schedules)
11
FTS Data Distribution
• The FTS mechanism for data distribution is a web portal. Selecteddata stored on the FTS server is made available for distribution by theFTS Distribution Server
• Customers desiring the system building blocks (e.g., ADL, algorithmsor RT STPS) interact with the FTS Distribution Server to downloadsource code distribution packages for these components
• Mission Support Data, updated regularly from the CGS, is similarlymade available to FTS customers
12
FTS Customer Registration and Reporting
• Customer registration for FTS access is a self service capability enabledthrough interaction with the Distribution Server main page
• Customer provided contact information is available to the FTSoperator for reporting purposes (e.g., to support requests forfrequency usage documentation) and notification purposes (to makeFTS customers aware of changes to in system status)
13
FTS System Status and Health
• The FTS internally monitors FTS component health and status, and logs relevantinformation on the FTS server to support FTS troubleshooting and recovery
• The monitoring approach planned for the FTS leverages existing capabilities usedfor monitoring DPES infrastructure. Expected items to monitor may include:
– Hardware Status,– Disk, CPU and Network Utilization– Server Availability– Process Status
16
FTS Block 2.0 TTO Path Forward
• Block 2.0 Changes for FTS– Inputs from CGS changing with Block 2.0:
• CGS Extranet Web Server • CGS Support Node content with Block 2.0
– Internal changes to FTS:» Checksum calculation differences (from
CRC to SHA 384)» Possible directory changes
– Output:• University of Wisconsin and GSFC Direct
Readout Lab (DRL) using FTS Web Portal instead of NPP External Mission Support Data Server (E-MSDS) for accessing Ancillary and Auxiliary Files

Progress to Date (1 of 2)
• The new FTS implementation plan was accepted by the Ground, PSE, and NJOmanagement, presented at the JPSS Customer Forum (Nov 2013), anddiscussed with key stake holders (Dec 2013)
• Upgraded HRD link receiver provided by the Svalbard Ground Station• Successfully awarded grants to NASA/DRL and Uwisc/CIMSS• Completed FTS Software and Hardware Design
– During the development of the Design Documents, three Peer Reviews were held (Junethrough August 2014) with Stakeholders
– Reviewers included the Integrators, JPSS Security, Mission Assurance and MSE– Comments received were incorporated into the next Draft of the Documents
• Supporting Documentation Developed (Subset)– FTS OpsCon Updated– FTS Level 3 and 4 Requirements Baselined– FTS Interface Definition Document (IDD) Completed– FTS Software Test Plan Completed
19
Progress to Date (2 of 2)
• The FTS SRR/SDR was successfully held on Apr 21, 2014– The IRT concluded that the artifacts clearly demonstrated that the FTS team has a
reasonable OpsCon, a good set of requirements, and a well thought out system
– Some of the key concerns included the scope of the FTS effort and clarification oncertain FTS requirements
– Received 6 RFAs and 4 ADV: All are closed
• The FTS CDR scheduled for Sep 17, 2014– The CDR was highly successful and the IRT was extremely pleased with the
proposed Software and Hardware Design
– The review panel approved the FTS team to proceed for implementation
– Received 5 RFAs and 2 RFIs: All are closed

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(IPOPP/CSPP) to demonstrate the ability to produce ready to use products from theSNPP/JPSS HRD link
• FTS will leverage existing annual workshops to provide a forum for the DB communityto present, discuss, learn, and provide feedback to the JPSS Program
