-WAG step 1 outcome -WAG step 2 plans -WAG in CNES project -WAG & GRID relations with other WGISS activities WAG Report Current Status and Plans, JP Antikidis, Paul Kopp,WGIS25,Sanya, febr.2008
WAG step 1 -Completed in end 2007 with final retained architecture: - Globus Toolkit - Open issues (Portal interfaces) - Send for comments to initial partner agencies (Ukraine, China)
WAG step 2 Prototype deployement : - Based on WAG step1 architecture (SOA) - Modifications according to partner reactions - Remaining open points be clarified - Architecture update - Sharing of Wide Area Grid functions - Full deployement toward sept.2008
WAG induced experience Not only technical but bringing: - Common appreciation of decentraised work - Demonstration of a distributed system responsibilities - Demonstration of a full decentralised while fully functional system => May induce interesting solutions for meeting GEO/GEOSS objective
WAG in CNES projects -Has been selected as the "ground part" for the e- CORCE programme (presented at GRID symposium ESA, january 2008) - Will be experimented in the frame of science distributed applications (CNRS/CNES Grid institute)
Paul Kopp – WGISS 24 – October, E-CORCE as a multilayer Space-ground GRID for 2015 ! 104 satellites, <10Meuros, 28 km swath,200 kgs, 80Mb/s, 100 Grid Nodes
Paul Kopp – WGISS 24 – October, The one-meter, one-day, one-Earth nightmare ! Some few figures extrated from current state of the art : 5x10 pixels/day= more than bits Overall satellite system raw troughput around 7000 Gigabits/s !! According to present sensor technologies ( pixels CCDs) means 125 Gb/s !!! 20 receiving centre with 700 Gb/s dump speed !!! How to break the information wall !!! ? Grid on the ground: yes,but not enough ! Distributed satellite,transmission, and receiving stations: yes but not enough ! We need : Information society techno and concepts +Grid integrating Space & Ground components in a one Shell
Paul Kopp – WGISS 24 – October, e-CORCE is a Grid-based distributed instrument Three fully integrated technical layers as a unified concept: THE SPACE CELLULAR LAYER: Makes use of a fully automated satellite constellation covering the whole earth in a systematic fashion (Saturation). Full cover is achieved typically in a 1 day time with a a 1 meter ground resolution (100 or more units are contemplated) THE TELECOM CELLULAR LAYER: Satellites are able to send immediatly their highly compressed (jpeg) information to ground centres. Telecom operation will be automated and highly simplified in such a way no station operator is required. Use of IP concept will suppress the need for separate TM/TC channels. THE GROUND CELLULAR LAYER (Wide Area Grid) Owing to the enormous quantity of information to be treated in a one day time, all processes will be fully distributed all over the Earth and allow an acceptable local workload. Grid technology is able to carry this organisation keeping in mind the Earth mosaic will never be centralised leading to a Virtual Earth creatioon (Looksd like e-Tube technology) e-CORCE cannot exist without getting together the full association of three highly distributed technical layers that makes it one and only one instrument spread all other the earth !
Paul Kopp – WGISS 24 – October, The system "brain" (Wide Aera Grid) Virtual Earth distributed 1 meter dayly mosaic Accessible from portals Pro Market Mass Market Thematic Market
Paul Kopp – WGISS 24 – October, Overall computerized capacity brought by 5000 PCs (2008), 1000 PCs (2015) spreaded over 50 to 100 receiving and processing centers may generate on a daily basis the world-mosaic at 1 meter resolution Typically any of he WAG node will make use of 20 PCs(2015) to create its local mosaic. E-CORCE Ground cellular processing requirementsl
WAG & GRID role with respect to upcoming WGISS/GEO issues -We need infrastructure for future for cooperative and automated systems (eg): -- Sensor Web (Web infra-structure) -- Integrated Constellation (LSI constellation) -- Thematic cooperative organisations
Paul Kopp – WGISS 24 – October, IP Satellites are seen by the system as space connected to WAG nodes. Each Node take care of: - data reception over the antenna footprint - Image decompression - calibration and local mosaic creation. Information stay on site and accesible from any client as a contributing IP to the world-wide mosaic IPs E-CORCE seen as a SensorWeb managed by a WAG
Paul Kopp – WGISS 24 – October, To day EO large scale objectives World-wide follow-on ozone World-wide follow-on of sea state (MERCATOR) World-wide follow-on of vegetation index World-wide follow-on of crop and food resources GMES programme GEO endeavour CEOS Constellations Sensor Web concepts.... Can we afford on the long run to pile-up investments as we do today ?
