Index

• Progress Meeting Technical presentation
• Introduction to Smog project (General view)
• Technical Presentation
• Project achievements
• Goals met in PAS,PGS,FEP,DDS and MAN.
• Advantages of the actual system
• Scalability of the system
• Full system distribution

3
Introduction

• The main objectives of the SMOG project are
• To define a generic architecture, applicable to
  the Ground Segment of Earth Observation Small
  Missions.
• To define an Advanced Ground Facility, AGF, as a
  basic node of the future ground segment.
• To define and to construct an AGF Prototype for
  the validation of the major concepts applicable
  to AGF.

4
AGF Prototype functions

• Acquisition of telemetry data from MODIS and ERS
  satellites
• Transformation of the telemetry into Computer
  Compatible Format
• Generation of EO products MODIS and ERS products
• Storage, archive and catalogue the EO products
• Dissemination of products to the EO data users

5
AGF Design concepts

• What were we facing at?
• Prototype with 5 Main subsystems
• 1 Manager controling the system
• Smart Communication design to cope with modular
  architecture
• Databases
• Product Procesors Integration reuse
• Reusability, Distribution etc...

6
AGF Design concepts II

• What do we have to show?
• 5 Subsystems
• Manager
• PAS. Product Archive S/S
• PGS. Product Generation S/S
• DDS. Data Dissemination S/S
• FEP. Front End Processor
• JMS communications.
• Scalability,distribution, portability and
  reuseability.

7
AGF Design concepts III

• AGF management framework based on a hierarchical
  architecture composed by two layer
• MAN
• PGS, PAS, DDS and FEP with their own local
  manager, task manager, responsible for managing
  its resources and internal activities.

8
AGF SW architecture S/S

• 1.- Initial Stage

Commands/response (JMS)

• 2.- Intermediate Stage

DB access (JDBC)

• 3.- Final Stage

9
AGF Protocols

• Control flow orders from AGF_MAN to S/S
• Using JMS Communication middleware (software bus)
• Data flow horizontal among S/S
• Using FTP
• Transferences granted by AGF_MAN to each S/S
• S/S perform FTP transferences (pull mechanism)

10
AGF SW architecture GUI S/S
11
AGF SW architecture COTS used

• Programming languages.
• Java 1.4.2 .
• JSP.
• Javascript.
• OS scripting.
• HTML.
• Database
• Oracle 9i
• Operative Systems
• Linux
• Windows XP
• FTP server
• Log4j
• OpenJms
• EPSI-ERS 1.2.6 SLC processor and Viewer
• MODIS IMAPP 1.5
• MODIS Scanview

AGF Performances

• Facts
• Orbit period time 100 minutes.
• IAGD process time for MODIS is 56 minutes.
• Conclusion
• Processing product within 60 minutes lt orbit
  period using low cost HW.

20
AGF Achievements (I)

• Demonstrate the feasibility of developing a
  low-cost system able to generate automatically EO
  products.
• Distributed system 4 platforms.
• Most of generic part of system coded in JAVA
  MAN, PAS, PGS, DDS -gt portable to other systems
• Specific components, that is processors, coded in
  C.
• FEP reconfigurable
• Simple use, complexity is resolved by background
  running S/S AGF MAN, PAS, PGS, DDS, FEP.

21
AGF Achievements (II)

• Puzzle of SW components
• Three operating system running
• Red hat Linux AGF S/S
• FEP and IQ Suse Linux
• Windows Client
• Processors
• MODIS downloaded from SSEC
• ERS reused EPSIE SLC processor from INDRA
• Quick-Look Viewers
• MODIS scan view
• Reused INDRA EPSIE component
• Several open source components used (JMS, Log4)
  used for implementation
• Web access
