Statement of Work Task: JPSS Flight Dynamics Analysis Task Order: 116 Task Modification: 5

I. Summary of Changes in this Task Modification

This task modification will extend the period of performance through the next task year.

Support for NOAA’s NEON program was added.

II. Summary of Work NOAA’s Near-Earth Orbit Network (NEON) Program will develop future low-Earth orbit (LEO) environmental satellites. Low and medium Earth observations are critical for weather forecasting, environmental observation, climate monitoring and public safety.

NEON sets the stage for NOAA to manage future polar and other low Earth and medium Earth orbit satellite observations as loosely coupled projects.

The Joint Polar Satellite System (JPSS) is the National Oceanic and Atmospheric Administration (NOAA) current operational low-Earth orbiting environmental observation program, which acquires and makes available global environmental data, primarily from multiple polar-orbiting satellites. The JPSS plays a critical role in NOAA’s continuing mission to understand and predict changes in weather, climate, oceans and coasts, which support the Nation’s economy and protect lives and property.

JPSS consists of a series of operational satellites – S-NPP, NOAA-20, and NOAA-21 (formerly JPSS-1 and JPSS-2), already in orbit, and JPSS-3 & -4 in development. All satellites fly in the same polar sun-synchronous mission orbit constellation. These satellites will share a common set of polar ground and space-based communications assets in order to downlink environmental data each orbit for subsequent data product generation and availability to the global user community. The next JPSS satellite launch is expected in 2027.

The JPSS and NEON Programs (Code 470) and Flight Project (Code 472) require flight dynamics-based modeling, analyses and technical support for conceptual mission analysis/design and mission requirement development/formulation.

III. Period of Performance The period of performance for this task will be from 11/01/2023 through 10/31/2024.

IV. Task Description This task order defines the tasks required to perform mission design analysis for mission concepts of operations in support of the JPSS program. This technical support effort is coordinated by the JPSS Program Systems Engineering (PSE) organization and is primarily in support of the JPSS Mission Orbit Analysis Working Group (MOAWG). An overview of the tasks are as follows:

Meeting & Review Support

This task provides support to various JPSS and NEON program and Flight Project reviews and working groups. The effort described includes consultation and expertise support in all areas of flight dynamics support including mission analysis, orbit determination, and launch vehicle support.

Specific reviews and working groups may include the following:

• Monthly technical meeting with the Task Monitor report assessing technical, staffing, and budget statuses

• Support the bi-weekly Mission Orbit Analysis Working Group (MOAWG) meetings

• Ground System TIMs and Working Groups – as needed

• Other mission TIMs and meetings - as needed

• Review Project Service Level Agreement (PSLA) and Network Requirements

Document (NRD)– as needed

• Review of ops products – as requested

• Mission Readiness Status Meetings

• Major mission review support (e.g., MOR)

Analysis Support

The following analysis items are anticipated for the next task year.

• Validate any information from the launch support entity identified in NEON mission contracts. The task will validate the information by making sure the desired orbit requirements have been met.

• Continue to provide ground station contact in views analysis and development of station loading models for JPSS and NEON managed and supported missions in the north and south hemisphere to support ground station utilization and loading studies.

Maintain current visibility models to ensure use of current station masks for Svalbard, Fairbanks, McMurdo and Troll stations. Develop and maintain constellation orbit models for SNPP, NOAA-20, NOAA-21, EUMETSAT Second Generation satellites, and notional NEON, Air Force, and DoD assets as necessary to generate the multi mission in view data to be used as inputs for both Flight Dynamics Support loading model development and validation of PSE loading analysis efforts.

• Provide any needed analysis of S-NPP and options for the post-JPSS-2 launch time period. This can include drift analysis of the MLTAN (Mean Local Time of the Ascending Node), a current fuel budget analysis, and de-orbit of S-NPP at its end of life.

• Provide analyses supporting the repositioning of satellites (S-NPP, NOAA-20, NOAA- 21, etc.) in the constellation.

• Provide lifetime projections for NOAA-20 & -21 as requested

• Provide analysis support of NEON, which includes QuickSounder. Analysis can include evaluation of various orbit/constellation analyses that also includes communication contacts. Orbit/constellation analyses could include optimizing the constellations for best coverage/contacts to analyzing individual maneuvers (from LV injection to ascent sequence/phasing sequence). These studies are new ventures being managed by JPSS PSE and are in the early phases of development. Details will be provided as they become available.
