BreadBoard/Prototype
• “pre-breadboard” the structure built with offthe-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 IPRR, during the Phase B1 (in the PLATO 1.0
context) , obtained from the breadboard,
replacing the L1 and L2 lenses.

Phase B1: SRR Objectives 1/2
• 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.
Catania, 11 June 2014
TOU Meeting
Phase B1: SRR Objectives 2/2
• 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.

TOUs during PLATO 2.0
Phase B2 goal
• 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

When Industrial Prime Contractor?
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.
