1. INTRODUCTION

The National Oceanic and Atmospheric Administration (NOAA) operates a constellation of geostationary environmental satellites to protect life and property across the United States.

The Geostationary Extended Observations (GeoXO) Program is the follow-on to the Geostationary Operational Environmental Satellites (GOES-R) Program. The GeoXO satellites will improve upon the imagery provided by the GOES-R series and introduce new technologies including sounding, ocean color and atmospheric composition instruments.

These advances will improve the nation’s ability to monitor and forecast weather and environmental phenomena. GeoXO is a collaborative development and acquisition effort between NOAA and the National Aeronautics and Space Administration (NASA).

The GeoXO Program is a series of six satellites, operated in a constellation of three satellites operating in geostationary orbit providing coverage of the eastern United States and most of the Atlantic Ocean, the western United States and Pacific Ocean basin, and the central United States including coverage of the coastlines. The satellites in the East and West locations of the United States (called GeoI satellites) will accommodate the Imager, Lightning Mapper, and Ocean Color instruments. The satellite in the Central locations of the United States (called GeoS satellites) will accommodate the hyperspectral radiometric Sounder, Atmospheric Composition, and Partner Instruments. The GeoXO satellites will provide critical atmospheric, oceanic, and climatic weather products supporting weather forecasting and warnings, climatologic analysis and prediction, ecosystems management, and safe and efficient commercial and private air and marine transportation.

This Statement of Work (SOW) specifies the Contractor requirements for performing Mission Formulation (Phase A) work to generate Spacecraft concept designs along with the necessary documentation for the potential future development of the GeoXO Spacecraft. This SOW is to prepare for the potential future release of a development contract for up to six (6) GeoXO Satellites (4 GeoI and 2 GeoS) and related services for the NOAA GeoXO program series of geostationary satellites. Each GeoXO Spacecraft will need to accommodate three

(3) earth viewing instruments.

Operationally, the GeoXO program will provide a satellite in the East (~75°W), Central (~105°W), and West (~137°W) along with a replacement satellite. To satisfy this operational strategy, the GeoXO satellite series includes of two East (GeoI), two West (GeoI), and two Central (GeoS) satellites for a total of six (6) Spacecraft. These satellites will replace the GOES East and GOES West series of Spacecraft along with adding the new GeoS (Central) Spacecraft:

1. GeoI1: replaces either GOES East or West Satellite

2. GeoI2: replaces either GOES East or West Satellite

3. GeoS1: inserted to view the Central part of the US

4. GeoI3: replaces either GOES East or West Satellite

5. GeoS2: inserted to view the Central part of the US

6. GeoI4: replaces either GOES East or West Satellite

Appendix D: Contractor Work Breakdown Structure (CWBS) and CWBS Dictionary

1. DESCRIPTION / PURPOSE

The CWBS establishes a product-oriented framework for reporting program cost, schedule, and technical performance and provides a basis for uniform planning, reporting status, program visibility, and assignment of responsibilities. Additionally, the CWBS provides a product-oriented logical subdivision of hardware, software, services, facilities, etc., that contribute to and/or make up the total project scope of effort and work. The CWBS dictionary provides a narrative description of the work tasks and effort to be performed in each CWBS element.

2. PREPARATION INFORMATION

2.1 Contents:

The CWBS and CWBS dictionary are two distinct project documents used for defining the approved project scope of work. The contents of each document are detailed in the following paragraphs:

CWBS – A logical, hierarchical display of the subdivision of all project work to be completed. The CWBS shall include the approved element title and element number.

CWBS dictionary – The CWBS dictionary shall briefly describe and document the work content of every CWBS element and relevant efforts associated with each element (e.g., design, development, and manufacturing).

The CWBS levels shall be governed by the following. The actual letter and number designations can be adapted to meet the needs of the Contractor’s system:

Level 1 - Total contract effort

Level 2 - Definitions: Major contract activity.

A. Non-Recurring Activities - All effort to plan and manage the design of a GeoXO spacecraft including detailed design activities, design reviews, risk reduction (engineering models, etc), software development, GSE development, verification planning, etc.

B. Flight Model (FM) -1

C. FM-2

D. FM-3

E. FM-4

F. FM-5

G. FM-6

H. Spares
