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).

RES-POE
Sentinels PDGS Industry Information Day,
5 May 2009, pg. 92
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.
Sentinels PDGS Industry Information Day,
5 May 2009, pg. 93
2. Best Practices
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.
Sentinels PDGS Industry Information Day,
5 May 2009, pg. 94
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

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.
