AIT Deliverables - E-14

Describe all the deliverables associated with the product to be integrated by the customer

A. Scope

The purpose of this document is to help to identify "Assembly, Integration, Test deliverables" (AIT deliverables), i.e. hardware and software supplies and documents associated with the delivery of flight equipment, with regards to it being taken into account by the entity responsible for AIT at a higher level (e.g. payload or satellite level for a scientific space instrument).

It should be noted that the list provided below is as exhaustive as possible, but that CNES may accompany the preparation of deliverables, documents in particular, in order to achieve just what is needed, depending on the complexity of the flight instrument delivered for example.

B. Fundamentals

The list of AIT deliverables is issued by the authority which receives delivery of the integrated and qualified product (e.g. a scientific instrument). The content of this supply is validated under a contractual form or under a partnership framework agreement.

This list is identified in the Assembly, Integration and Test Plan (AITP) and/or in the Integration Quality Assurance Plan (IQAP) which covers a product's AIT activity.

The product AIT Manager (RAIT) is responsible for the supply of "AIT deliverables".

C. Typical content

1. Scope

This chapter must contain the general information that defines the content of the "AIT deliverables" supply covered by the document.

2. Deliverable AIT documentation

The deliverable documentation must enable the high-level AIT Manager to trace all details concerning the configuration of the product and equipment delivered, concerning their operation and their performance, risks induced by this equipment, the major stages in the life cycle (anomalies, test results, qualification status) and the validation test requirements at a higher level.

We assume that some "Product assurance" type documents are generally delivered before the higher-level AIT phase.

These include, in particular:

  • the list of materials and processes used
  • the list of EEE components

 

Deliverable documents accompanying the supply of the flight model are principally:

  • the design document ;
  • the mechanical, thermal, electrical, software, TMTC (telemetry/telecommand) Interface Control Document (ICD) ;
  • the User Manual (UM) or Implementation Manual (IM), specifying:
    • how to operate and test the product (TMT C plans and TMTC formats), in which configuration, with which ground facilities,
    • the cleanliness, safety and critical parameter monitoring threshold directives/requirements,
    • the procedures conducted (AS-RUN) (at least available for consultation),
    • integration reports (at least available for consultation),
    • the handling, storage/removal from storage and transportation procedure.
  • The End-Item Data Package (EIDP), which incorporates:
    • Cover page,
    • Revisions table,
    • Contents,
    • Certificate of compliance,
    • Status of modifications,
    • Status of incorporation of modifications,
    • Status of anomalies and waivers,
    • Status of open tasks,
    • Observations,
    • Inspection reports.
  • The Log Book (LB), which clearly indicates the phases of the product's service life, from the time it is assembled to its delivery (retrofits, tests, transportation, number of critical mechanism activations, etc.) and incorporates:
    • Cover page,
    • Revisions table,
    • Contents,
    • Component parts lists,
    • List of limited-life items,
    • List of usage limits and parameters to be monitored,
    • List of procedures delivered
    • List of Ground Support Equipment (GSE)
    • Record of configuration changes,
    • Record of operating time,
    • Record of connector connections/disconnections,
    • Record of protection items,
    • Record of anomalies/waivers,
    • Record of tests/inspections,
    • Record of events.

 

The Test Requirements Document (STBE) or Test Request (TR) at higher level, which describes the verification tests to be performed with regards to the product when the latter is integrated into the system (e.g. tests to be performed on a scientific instrument during satellite thermal vacuum test).

3. Deliverable flight hardware and software

These are flight model products (e.g. nominal instruments and spare part instruments), equipped with their flight software if necessary, which are the main subject of the delivery, and which will be taken into account in the highest level AIT activity.

The following accessories are generally associated with these flight models:

  • interface connector savers (in particular for specific type connectors),
  • if necessary harness connectors opposite instrument connectors (in particular for specific type connectors),
  • non-flight protection covers, generally painted red (e.g. protection cover for an optical device, to be removed during shooting tests, and before flight), connectors protection ground plugs.

 

4. Deliverable Ground Support Equipments (GSE)

These are peripheral facilities required on ground to perform the AIT of the product delivered at higher level (e.g. assembly and tests of an instrument on a satellite):

The ground support equipments are described in the document ref. I-10 Assembly, Integration and Test Plan.

This involves supplying specific ground facilities with delivered flight models to assist with their implementation. At least the following documentation will also be supplied (User Manual, calibration tables). The supply may include (non-exhaustive list):

  • handling tool yoke,
  • transportation and protection cover,
  • nitrogen ventilation system,
  • transport container,
  • stimuli, as collimator,
  • break-out boxes corresponding to the various instrument connectors,
  • test bench,
  • instrument test sequences and database (to be incorporated at system level),
  • etc.
