Breadboard/

Prototype

TOU Meeting

• “pre-breadboard” the structure built with off-the-shelf lenses used to test GSE and procedures to be used with the breadboard.

• “breadboard” the structure built to test alignment in warm and cold environment before the I-PRR

• “prototype” the structure built after the I-PRR, during the Phase B1 (in the PLATO 1.0 context) , obtained from the breadboard, replacing the L1 and L2 lenses.

PLATO 2.0 timeline – Phase B2C/D/E1Q1 2016-Q1 2024

Catania, 11 June 2014

Premises

TOU Meeting

• PLATO Phase B1 objective is the adoption of the PLATO mission by SPC in Feb-March 2016.

• The PLATO System Requirements Review (SRR) to be completed by January 2016 is a major input to PLATO mission adoption.

• The SRR is a formal review (category 1 i.e organized by ESA inspector general, D/SRE is the chairman).

• The primary objective of the SRR is to review in detail:– The final payload and spacecraft system specifications,– The payload and spacecraft design definition,– The payload and spacecraft development and verification program,– Mission programmatic and cost.

Phase B1: SRR Objectives 1/2

Catania, 11 June 2014

Premises

TOU Meeting

• The camera development schedule is critical, and is actually defining the schedule critical path for the spacecraft. Hence:– The camera detailed design activities (including AIV plans and Ground

System Equipment design) shall be completed before the SRR,– The critical bread-boarding activities (e.g. electronics Demonstration

Models, optics) shall be initiated during phase B1,– Consortium input to the SRR shall demonstrate that the camera

Engineering Model - which is fully representative of the flight model except for some electronics parts - will be completed by early 2017,

– A detailed development plan of the payload shall demonstrate by SRR that:

• serial production phase will start by mid-2017,• the first batch of 8 cameras will be delivered in November 2020,• the last batch of cameras will be delivered by November 2021.

Phase B1: SRR Objectives 2/2

Catania, 11 June 2014

Premises

??

Our proposal: deliver all ready but undelivered documents:

• Design:– Consolidated TOU Design Report (Optical Design, Mechanical Design,

Thermal Analysis, Stray-light Analysis, Optical Material Analysis and Coating Design, ..)

• Breadboard:– Consolidated BreadBoard AIV report

• NEW: including a critical review of results and assessment of some open issues

• CaF2 tests

• AIV Design:– Consolidated TOU MAIT and Management Plan – Consolidated AlBeMet® Mechanical Structure Procurement

Assessment Study– NEW: F-TOU Filters Design Procurement Assessment Study

TOUs during PLATO 2.0Phase B1 goal

TOU Meeting

• Design:– Engineering of TOU Design (Optical Design, Mechanical Design,

Thermal Analysis, Stray-light Analysis, Optical Material Analysis and Coating Design, ..)

• Breadboard Prototype– Lens set like the FM one (change of 2 lenses and replacement of

one lens previously accepted with no conformance issue because short in time

– optical quality test (in term of PSF shape and dimension) on the whole FoV.

• AIV Design:– Finalized TOU MAIT and Management Plan – Finalized AlBeMet® Mechanical Structure Procurement Study– Consolidated: F-TOU Filters Design Procurement Assessment Study

TOUs during PLATO 2.0Phase B2 goal

Catania, 11 June 2014

TOU Meeting

Our proposal:• During Phase B1, industry will deliver consult

and services.• We’ll work to have ASI delivers a ITT for

Phase B2/C contract, not later than March 2015.

• Goal:– TOU Prime Contractor at work at beginning of

Phase B2, but clearly identified before the SRR.

When Industrial Prime Contractor?
