Instrument Interface Document (UIID)

1 Scope

The purpose of this Unique Instrument Interface Document (UIID) is two-fold. The first is to allocate GeoXO series spacecraft resources to the Ocean Color Instrument (OCX). The second is to serve as a core building block on which the OCX-spacecraft interface can be designed. The spacecraft integrating contractor and the OCX contractor will meet each of their respective interface requirements as defined in this document.

This UIID will govern the development of an Interface Control Document (ICD) which will be a joint activity of the OCX and spacecraft contractors.

The OCX ICD establishes the details of the electrical, communications, mechanical, thermal, integration and test, and command and data handling (C&DH) interfaces between the OCX instrument and the GeoXO spacecraft. After the ICD is signed and approved by all parties, the spacecraft contractor will maintain the ICD.

The OCX is a hyperspectral imager in geostationary, or GEO, orbit. Hyperspectral imaging collects and processes information from across the electromagnetic spectrum including visible light, near-infrared and ultraviolet frequencies to create a highly detailed view of physical and biological conditions in coastal waters. The instruments will collect data on a three-axis body-stabilized satellite in geosynchronous orbit.

Data availability, radiometric quality, simultaneous data collection, coverage rates, scan flexibility, and minimizing data loss due to the sun are prime requirements of the system. The instrument requires primary power, and command input data from the spacecraft. Instrument output data to the spacecraft contains instrument information, instrument telemetry and ancillary data.

The sensor units contain the optical system, scanner, detectors and their cooling/heating systems and directly related electronics. The electronics unit contains the power supply module, command, control, and data processing circuitry.

If required, an auxiliary electronics unit may be used for active detector temperature regulation.

1.1 Document Overview

Together, the General Interface Requirements Document (GIRD) and the OCX UIID establish the OCX-spacecraft interface requirements. The GIRD applies to all GeoXO instruments while the OCX UIID is specific to the OCX. Section 1 explains the use of this document. Section 2 lists reference documents. Section 3 allocates spacecraft resources, such as mass, power, and data rate, to the OCX instrument. Section 4 contains government-accepted operation constraints. Section 5 contains government-accepted deviations from the GIRD. Section 6 contains Design Verification Requirements. Section 7 contains a list of acronyms used within this document.

1.2 Requirements Terminology

The following requirements terminology is used throughout this document:

The use of “shall” designates a requirement that must be met. (CCR-X00052)

Instrument Interface Document (UIID)

The term “should” designates a desired level of performance the government would like the contractor to strive towards achieving and is synonymous with the term “goal.”

The use of “will” designates a statement of fact or intention of the government.

(CCR-X00052)

The term “TBD” means, “to be determined” and is used when no value is available with subsequent study needed to obtain it. (CCR-X00052)

The use of “may” designates that permission has been granted by the government.

(CCR-X00052)

TBD requirement proposals are to be made in coordination with the government and may involve other contractors.

The contractor should request approval from the government before proceeding with its proposed TBD requirement or value.

The term “TBR” means means “to be refined/reviewed” for a value that is subject to review for appropriateness and is subject to revision. The Contractor is liable for compliance with the information marked “TBR” as if the “TBR” notation did not exist.

(CCR-X00052) (CCR-X00206)

TBR requirement proposals will be made in coordination with the government and may involve other contractors.

The contractor should request approval from the government before proceeding with its proposed TBR requirement or value.

The term “TBS” means, “to be supplied.” The government will supply TBS requirements. The government will provide a date or milestone at which each TBS requirement will be supplied.

The orbit reference frame (ORF), and the body reference frame (BRF), will be as defined in the GIRD.

1.3 Order of Precedence

The order of precedence of interface requirements documents is the UIID at the highest level, followed in order by the GIRD, ICD, and Instrument Description Document (IDD).
