Sentinels PDGS Demodulator and Front End Processor

Technical Assessment and Market Survey
The technical feasibility assessment has shown that a common procurement is feasible across Sentinels: RF level – commonality confirmed. Data level (commonality based on standards, e.g., CCSDS) Downlink Channel Management – Commonality issue found. Sentinel 3 only: inter-channel downstream dependency (implies extra development and more stringent ground performances) – Function allocation still TBC. Other differences are mainly at configuration level. The market survey indicates the presence of some equipment closed to Sentinel needs (not extensive development phase expected).

Sentinels PDGS Mission Planning

On-board recording resource management (packet store management)
Procurement Scope Instrument Planning On-board recording resource management (packet store management) Downlink Planning Handling of multi-satellite constellation as single resource Support to local Stations Support to EDRS X-Band conflict handling to be solved outside mission planning by operational agreements

FOS interface: customized from Earth Explorer missions interface
Mission Planning Interfaces FOS interface: customized from Earth Explorer missions interface Mission Management Interface for ingestion of systematic observation requirements from GMES Service Providers User Service interfaces to be based on current multi-mission ICDs with possible customizations Station Interface to be based on multi-mission station interface with possible customizations

Mission Planning: S-1 variable on-board compression make location of actual downlink difficult to predict ==> mission planning probabilistic packet store management algorithm requires capability of stations and assembly centres to handle non-nominal scenarios MP was incorporated into the PDGS contract => "best practise" approach Output: fully operational system integrated in PDGS and support to commissioning phase

Variable Compression Algorithm
Mission Planning System will need to rely on an external library that evaluates the expected compressed size of each data take size evaluation has to be provided with a probabilistic approach (i.e. with 95% of probability the size will be smaller than ...) library to be provided as part of PDGS development ==> expert knowledge required

separate MP system will be procured as separate competitive tender
Mission Planning: S-2 separate MP system will be procured as separate competitive tender Output: fully operational system support to integrate the system into the PDGS support to commissioning phase

systematic planning, no conflict management due to user requests
Mission Planning: S-3 systematic planning, no conflict management due to user requests procurement as separate tender by Eumetsat

Sentinels PDGS: Best Practices for the Selection of Subcontractors
Luc Govaert RES-POE

1. Best Practices Code of Best Practices, Definition and Governing Principles/Purpose of Best Practices ESA has a Code of Best Practices, approved by the Industrial Policy Committee as industrial policy ruling. Definition of Best Practices: Basically, a mechanism through which a Prime selects subcontractors for a given element within an ESA programme prior or subsequent to his own selection by ESA. The principle and purpose of Best Practices is to achieve fairness of competition at all levels (Prime and subcontractors) and to guarantee fair, impartial and equal treatment of non-primes.

PDGS Best Practices: Origin and Extent
Statement in the ESA Procurement Plan approved by IPC: “The ESA Best Practices may be followed for some elements within the PDGS Core Procurement.” The bulk of the Sentinels PDGS procurement will be placed further to ESA ITTs, only a limited part through Best Practices (up to 40%). ESA will decide which elements of a given procurement will be awarded through Best Practices.

Implementation and Guarantees to ensure Fairness of Competition (I)
3. Best Practices Implementation and Guarantees to ensure Fairness of Competition (I) ESA shall have full visibility on the ITT preparation by the Prime (ITT package to be approved by the Agency), on the evaluation and on the selection (Prime’s recommendation will be submitted to ESA; ESA will either endorse the recommendation or request to submit the recommendation for decision to a Joint ESA/Industry Procurement Board), with the right to audit the full process. The Prime shall have to state his acceptance of the Best Practices principles and of his obligation to organize Best Practices.

Implementation and Guarantees to ensure Fairness of Competition (II)
3. Best Practices Implementation and Guarantees to ensure Fairness of Competition (II) To guarantee impartiality, the Prime shall be required to accept and cooperate with the Agency’s Industrial Ombudsman. The Prime shall have to implement a SIMPLIFIED Best Practices selection procedure drafted by ESA and based on the principles of fair and open competition (procedure will be included in the ESA ITT package). IITT and ITT to be approved by the Agency and issued on EMITS (EXTERNAL ENTITIES) and CORDIS.

Implementation and Guarantees to ensure Fairness of Competition (III)
3. Best Practices Implementation and Guarantees to ensure Fairness of Competition (III) Conflict of interest: If the Prime and/or any subcontractor wish to bid for any element, the Prime/subcontractor shall be excluded from the evaluation of the proposals, this in the interest of impartiality and the Agency shall run the TEB. Same applies in case of companies belonging to the same industrial and/or legal organisation, or affiliated companies, meaning any form of association giving a company a vested interest in the outcome of the evaluation. However, the Prime’s responsibility vis-à-vis selected subcontractor is left untouched.

Implementation and Guarantees to ensure Fairness of Competition (IV)
3. Best Practices Implementation and Guarantees to ensure Fairness of Competition (IV) ESA Staff may be involved in the Tender Evaluation Board set up by the Prime (one Technical Representative, ESA CO at his discretion). Notwithstanding this, the Agency at any moment reserves the right to initiate a parallel evaluation performed by its Staff in accordance with the ESA tender evaluation process. Confidentiality of proposals submitted will have to be guaranteed by the Prime. The SoW/technical requirements, to be written by the Prime and to be reviewed and approved by the Agency, shall not be ambiguous or company tailored. The selection criteria shall be defined and made available to all potential bidders.
