SCOPE

2.1

Purpose

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

2.2

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. This will be the same Bus design as used for predecessor WorldView Satellites. The Instrument 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. 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.

2.3

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.

3.	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.

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.
