8. BreadBoard/Prototype
“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.

16. Phase B1: SRR Objectives 1/2
Premises
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

17. Phase B1: SRR Objectives 2/2
Premises
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. ??
