Customer are pushing for new products that evolve rapidly

For some years, synergies between information society and spatial technologies have become tangible, generating new standards for customer demands:

“I want to communicate with everyone at any time” (mobile telephony and Internet)

“I want to know where I am and where I’m going to” (Personal Navigation Devices market)

“I want to see everything at any time” (geolocalisation services e.g.: Google Earth, e-Globe…)

1 meter, Full Earth in a 1 week time or less with e-CORCE1 meter, Full Earth in a 1 week time or less with e-CORCE

Can we imagine one may create a self-sustainable satellite system able to photograph the whole of our planet with one-meter resolution on a one-day time?

e-CORCE stand for "e-Continuous Observing system Relayed by Cellular processing Environment"

"e-" since aiming at feeding geocoded information to Internet based mass market operators

"Continuous Observing" since aiming at providing a continuously refreshed view of our full planet

"Relayed by Cellular processing Environment" since based on the intimate compound of 3 cellular layers Space,Telecom,Grid

The one-meter, one-day, one-Earth nightmare The one-meter, one-day, one-Earth nightmare

Some few figures extracted from current state of the art :

5x10 +14 pixels/day = more than 10 000 000 000 000 000 bits

Overall satellite system raw throughout around 7000 Gigabits/s

According to present sensor technologies (20 000 pixels CCDs)means 125 satellites @67 Gb/s !!!20 receiving centre with 700 Gb/s dump speed !!!How to break the information wall?

We need to COMPRESS & DISTRIBUTE the information flow

COMPRESS: Psycho-visual image compression

DISTRIBUTE: Receive and treat the information in a fully decentralised fashion without having centric facilities (WAG)

13 satellites, 28 km swath, 250 kgs, 80Mb/s, 50 receiving/processing nodes No end user distribution and no central facility, no full mosaic creation, end

product is logically distributed but never “physically” available Internet IP virtual products (eg: I-tune, I-tube or emule functionning)

Psycho-visual image compression (gain=50)

Psycho-visual data compression features (geared up for internet users):

No need for cloud cover handling

No need for sea surfaces on/off

Automatic bit budget

Compression over clouds / seas >100

Compression over Towns <15

Average compression all over the world >50

Nearly no visual degradation for 1m resolution images

Quality for 10 meters or more data anyhow excellent thanks to statistical surface averaging

Nodes are receiving systems and computers

=> Unified Satellite resources

Wide Area Grid (WAG) :Satellite GRID= Networked Nodes & Middleware

Reception of compressed payload data

Uplink of TM/TC commands (Space IP flow/protocol emulation)

Image decompression (adaptative JPEG2000)

Image correction

Local Mosaic creation

Interaction with other Node under WAG supervision

Resulting data set seen as data stream serveur , WAG IP streaming protocol

Distribution by peer to peer mechanism creating a full virtual metric Earth

Overall computerized capacity brought by 5000 PCs (1000 in 2012) 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 the WAG node will make use of 20 PCs to create its local mosaic.

Overall power close to the full CERN capability !

Is one meter a good choice ?

- Technical optimum for micro-sat techno- Well fitted to market usage- Good for visual navigation - Acceptable bandwidh and information sizing

Where is the stadium ?

Here it is !

“Getting weekly metric colour high resolution pictures of any place all over the world is becoming affordable to every-one and as straightforward as being plugged on Internet”

e-CORCE, “the easy way” for thematic users

Without need for sfecific programming :

Déforestation

Drought

Pollution

Roads

Harvest evaluation

Mineral and oil serach

Urban monitoring

Some revolutionary consequences on space Earth Observation utilization and business potential

The whole of the Earth is continuously accessible

No programming, no competition on satellite access

Any country will be covered the same way (poor and rich )

e-CORCE, the system for development aid and monitoring

Psycho-visual quality trimmed to maximize utilisation while cutting costs

e-CORCE, the Earth Observation « MP3 »

The whole planet is constructed as a virtual globe complete, fresh and homogeneous

No more catalogues

The full data set is « on line »

Oversimplified distribution at minimum cost trough Internet: ”Imagery On Demand” (IOD) 

Fully automated process from satellite to users :

Commercialization platform , the « Amazon » way with small or large deliver of pictures from any place all over the Earth !

And finally :

Imagery at much reduced cost by a factor of 4 at least inducing new markets opportunities and value added activities

Blue Planet objectives are to:

Involve European industry in the development and the operation of e-CORCE constellation

Operate and sale the worldwide metric images updated every week

Blue Planet will be a space imagery “wholesaler” supplying all users (Mass, Thematic, New)

Blue Planet ambition is to build an European dominant position thanks to its performance, its low cost and ease of access

Blue Planet, a new European space operator
