HMA target Architecture<br />
For <strong>Spot</strong> Image context, the mission ground segment and commercial entity are<br />
operated by a single entity.<br />
• The User Management service is integrated with the different technical services.<br />
SPOT & <strong>Pleiades</strong> services compliant with HMA published services<br />
GSCB<br />
June 2007 – Slide 3
SPOT/PLEIADES strategy and<br />
assumptions<br />
<strong>Spot</strong> Image Ground Segment will offer different services compliant with the ICD’s<br />
defined in the study phase of HMA Project.<br />
• These services allow an homogeneous and standardized access to SPOT and <strong>Pleiades</strong><br />
servers : Service Discovery, Catalog, Programming, Ordering, On line Data Access, User<br />
Management.<br />
• The maturity of different components of SISA IT involved in this Implementation Plan is very<br />
variable : SPOT system under exploitation since 1986, <strong>Pleiades</strong> launch scheduled in 2009.<br />
CNES / SPOT IMAGE overall strategy<br />
• Step by step implementation<br />
• Step 1 – SPOT services implementation on existing SISA IT infrastructure<br />
• Step 2 – SPOT services integration with DAIL (end to end tests)<br />
• Step 3 – Benchmarking of the overall process<br />
• Step 4 – PLEIADES services upgrade<br />
• Step 5 – PLEIADES services integration with DAIL<br />
• Step 6 – SSALTO altimetric data Ground segment (Topex/poseidon, Jason 1, Jason 2, …)<br />
services integration with DAIL<br />
Moreover many other <strong>Spot</strong> Image IT components are also concerned by HMA services<br />
and have to be taken into account in the overall strategy<br />
• Production Workflow management,<br />
• Business Workflow management (including : request for quotation, pricing and billing).<br />

<strong>Spot</strong> Image Ground Segment<br />
implementation : Ordering example<br />
SPOT/<strong>Pleiades</strong> ordering services have not been<br />
developed in consistency with HMA ICD’s<br />
• Front End shall be developed to communicate with the HMA<br />
protocol.<br />
The getQuotation Service shall be implemented in consistency with<br />
business Workflow (GESD2P/gescom from SISA IT)<br />
So the implementation phase requires the development of dedicated<br />
façade<br />

SLA key issues<br />
A Service Level Agreement will be prepared for each of the services relevant to HMA<br />
implementation (could be different between SPOT and PLEIADES)<br />
• catalogue and discovery services for SPOT and PLEIADES<br />
• programming services for SPOT and PLEIADES<br />
• ordering services for SPOT and PLEIADES<br />
• user management services for SPOT and PLEIADES<br />
• on-line data access services for SPOT and PLEIADES<br />
SLA will include (preliminary figures provided inside IP draft)<br />
• definition of the service<br />
• category of users that are authorised to access to the service<br />
• rights granted to the users<br />
• procedure to access to the service<br />
• performances of the service (volume, response times, availability, etc)<br />
Commitments on SLA are difficult because<br />
• priority assigned to a user is generally depending on its financial commitment with the ground segment<br />
operator. The higher price the user will pay, the higher level of service he will obtain. It is therefore difficult to<br />
estimate the performances of the services without any knowledge of the financial component of the DAA<br />
• performances figures that are included in the Service Level Agreements are the current performances of the<br />
ground segments (existing performances for SPOT, specified performances for PLEIADES) without any HMA<br />
interface or DAIL.<br />

<strong>Spot</strong> Image Ground Segment<br />
implementation : Critical items<br />
The compliance with SLA requirements (performance, availability) should be<br />
a critical point.<br />
<strong>Spot</strong> Image IT architecture and global software architecture : façade layers,<br />
legacy database are imposed and mandate a two-step implementation plan<br />
• First step: functional SPOT services implementation based on existing IT<br />
infrastructure ;<br />
calibration/evaluation/benchmarking of performances reached by infrastructure (global<br />
infrastructure including ESA portal and DAIL layers)<br />
set up diagnostics of benchmarking phase : identify bottlenecks, performances<br />
problems, time consuming layers…propose update IT architecture<br />
• Second step: Implement update IT architecture for SPOT services<br />
