WV3 Satellite Statement of Work_ Doc Number 10329656

1.0 Introduction

This Statement of Work defines those tasks to be performed by BATC, the Space Segment Integrator, in defining; designing, producing, testing, verifying, and preparing for launch; the DigitalGlobe WorldView 3 Satellite. BATC has the overall responsibility for Satellite performance, as defined in the WV3 Satellite Specification, provided the DG-furnished Instrument meets its interfaces and specifications as defined in Paragraph 2.2. Within this role, BATC has the responsibility to work with DigitalGlobe to define requirements, allocate budgets, analyze performance, execute trade studies, interact with other vendors, define configurations(s), conform to existing Instrument interfaces, assess and mitigate risks, prepare various programmatic documentation, and interact with all participating organizations via meetings, teleconferences, and reviews as defined herein.

BATC shall provide integrating services as defined herein and the hardware and software, exclusive of Customer Furnished Equipment, that comprise the WV3 Satellite.

This document also defines the scope of work required from DigitalGlobe and associated subcontractors in order for BATC to execute this contract successfully.

Associate contractors under contract to DigitalGlobe shall provide the Instrument and Launch services. However, BATC shall fully support defining, documenting, and verifying Satellite(s) to LV and MGB interfaces and integration procedures. BATC shall insure that the Satellite will withstand all launch environments.

1.1 Definitions

Agreement: Satellite Purchase Agreement #60150 by and between DigitalGlobe, Inc. and Ball Aerospace and Technologies Corp., dated August 27, 2010, as amended.

Authorization to Proceed (ATP): Effective date of work commencement per the Agreement.

Satellite: The complete space-borne infrastructure required to perform the mission of providing radiometrically and geometrically correct imagery of the Earth. The Satellite consists of the Instrument and the Spacecraft Bus.

[**Redacted**]

Instrument: The Instrument is that part of the Satellite that collects light photons using appropriate mirrors and structure, [**Redacted**]. It also may be designated the Electro-Optical Assembly (EOA). The instrument includes its own thermal control system. However, the instrument focus mechanism depends upon drive electronics to be provided by BATC per this Statement of Work. Also, the instrument stimulation lamp depends upon drive electronics to be provided by BATC per this Statement of Work.

Telescope: That part of the Instrument that collects and focuses light onto a focal plane. [**Redacted**] It also may be designated the Optical Telescope Unit (OTU).

Sensor Subsystem (SSS): That part of the Instrument that converts photons to analog voltage signals, [**Redacted**], and digitizes [**Redacted**] those signals.

[**Redacted**]

Solid State Recorder: The subsystem that accepts digital data from the SSS and Ancillary Data from the spacecraft bus, provides storage, [**Redacted**] and outputs that data to the wideband transmitter(s).

Spacecraft Bus: The Bus is that part of the Satellite that provides the support infrastructure so the Instrument can function.

[**Redacted**]

MGB: “MGB” is a meaningless three letter designation for an additional subsystem being installed on the WV3 satellite. The MGB subsystem consists of three components. The first is a Sensor Unit (SU) which will attach to the aperture end of the OBA. The second is the Interface Adaptor Unit (IAU) which will mount to the spacecraft bus. The third is an inter-connect cable which connects the first two units.

Initial Acceptance: Occurs upon successful completion of the Satellite Pre-Ship Review as defined in paragraph 4.5.3.2.e

Final Acceptance: Occurs following satellite fueling operations and completion of the Satellite Launch Readiness Review as defined in paragraph 4.5.3.2.f

WV3 Satellite Statement of Work_ Doc Number 10329656

Transfer of Title: Occurs as defined in the Satellite Purchase Agreement paragraph 8.

1.2 Program Overview

Under this Scope of Work, DigitalGlobe will procure one satellite to support the EnhancedView program and future commercial operations. DigitalGlobe shall provide the Instrument as Customer Furnished Equipment via a procurement contract with ITT. DigitalGlobe shall provide the “MGB” subsystem. As on the WV2 program, BATC shall deliver a WorldView 2 like stimulation lamp that will be incorporated into the ITT provided instrument. BATC shall also incorporate into the Bus, an instrument focus mechanism electronics capability.

DigitalGlobe shall provide the Launch Services via a procurement contract with Lockheed Martin-Commercial Launch Services. Lockheed Martin-Commercial Launch Services has in-turn subcontracted with United Launch Alliance to provide the Atlas V launch vehicle and associated launch services. BATC can assume an Atlas V launch vehicle and a launch from Vandenberg Air Force Base. BATC shall assume satellite processing at Vandenberg AFB will occur in either the Astrotech Payload Processing facility or the Spaceport Systems International Processing Facility.

1. SCOPE

1.1 Purpose

This document describes the requirements for design and implementation of the DigitalGlobe WorldView-3 Satellite, being constructed to support DigitalGlobe commercial imaging operations.

1.2 System Overview

Ball Aerospace & Technology Corporation (BATC) is providing the integrated WorldView-3 imaging satellite to DigitalGlobe, Inc. As the Space Segment Integrator (SSI), BATC is manufacturing a Spacecraft Bus that can accommodate the panchromatic + multi-spectral WorldView-3 Instrument [**Redacted**]. This will be the same Bus design as used for predecessor WorldView Satellites. The [**Redacted**] is being supplied by ITT Industries Space Systems Division (ITT) to DigitalGlobe, with miscellaneous support units / functions provided by BATC. All ITT equipment will be provided as Customer Furnished Equipment (CFE) to BATC for Satellite integration. [**Redacted**] As the SSI, BATC will then perform Satellite level testing, prepare the Satellite for launch, and support on-orbit checkout of the Satellite.

The Satellite will be in a sun-synchronous orbit at an altitude between 450 and 830 km with a descending equator crossing time between 10:00 AM and 2:00 PM. [**Redacted**] Image data is recorded by the Spacecraft Bus and is normally downlinked to DigitalGlobe ground stations. However, direct downlink to user sites may also be performed in certain circumstances. Direct downlink is via the normal wideband downlink.

A key feature of the WordView-3 Satellite is Direct Tasking, where imaging and downlink parameters are directly uplinked from a customer’s ground station to the satellite, and image data is directly downlinked to a customer’s ground station, on the same and/or successive passes. Direct Tasking supports an expanded customer base and fulfills these customers’ desires to compress the overall planning-tasking-collection-downlink timeline and to not expose their task list to outside parties (including DigitalGlobe) prior to image collection. Full command authority is maintained by DigitalGlobe, with key commands needed to initiate the image and downlink operations uploaded from DigitalGlobe ground stations.

1.3 Document Overview

This document specifies functional, performance and interface requirements for the integrated Satellite and the Spacecraft Bus, including external Satellite interfaces, Instrument-Bus interfaces and Instrument integration, Bus and Satellite test, launch, and operational requirements. Separate Interface Control Documents (ICDs) detail the specifics of the Instrument-Bus interfaces and Integration and Test processes. Satisfaction of the Satellite-level requirements contained in this specification assume the Instrument provided as CFE meets its requirements, which are documented separately. As the SSI, BATC will refer to the separate Instrument Specifications as necessary to maintain the Spacecraft Bus to Instrument ICDs and develop an integration and test plan sufficient to ensure the integrated Satellite meets its system-level functional and performance requirements.

This specification may contain requirements that have not been fully defined. These open requirements are indicated by a TBR, and/or TBD:

TBR – To Be Resolved: Indicates parameters that exist, but may change after discussions with Contractor and others (e.g.: DigitalGlobe).

TBD – To Be Determined: Indicates parameters that have not yet been determined.

2. APPLICABLE DOCUMENTS

This document is the Satellite Specification. This specification defines the technical requirements called out in the Contract and a Statement of Work (SOW). The Contract and SOW define schedule requirements, deliverable items and programmatics. However, in the event of a conflict between a specific requirement herein and documents, then the Contract, the Statement of Work, this document, and Applicable documents shall govern in this order. If the revision is not specifically noted, the latest revision of each document applies.

At contract signing, the Environmental Design and Test Specification and Interface Control Documents from predecessor DigitalGlobe WorldView satellite programs listed below shall be considered the baseline release for WV-3. It is anticipated that the WV-3 versions of these documents will require few modifications from the predecessor baselines, with changes focused in a few key areas as driven by WV-3 unique requirements (for example enhanced Instrument thermal control and updated power values). The first release of the WV-3 version of each document shall supersede the predecessor version, which shall no longer be considered an Applicable Document.

WorldView-3 Satellite Specification Doc’t # 10329655 Rev 8.0: 2 Nov 2011

Although the Satellite Integrating Contractor physically maintains many of these ICDs, their development is inherently a cooperative process. Accordingly, the latest released ICD revision shall always apply, where release is predicated on mutual agreement between all involved parties; for example the Instrument to Spacecraft ICD requires consensus between the Satellite Integrating Contractor, the Instrument Contractor, and DigitalGlobe.
