GEO-NETCastWhat is it?

GEO-NETCast is a near real-time data dissemination system -- in support of the GEO societal benefit areas -- by which environmental in situ, airborne, and space-based observations, products, and services are transmitted to users through satellites.

Why?

To provide environmental data to users who would not otherwise have access to it.

When?

Target is to complete the global demonstration by the end of 2007

Overall Concept

• A global broadcast system for the delivery of data, products, and services contributed to GEOSS

B Data from in-situ and space-based observing systems in standard formats

B Supporting all nine GEO societal benefit areas

B Built on existing dissemination systems with data collection hubs around the globe

• Transmitted to affordable ground receiving stations through satellitesB Situated to provide global coverage

B Use of standard, multicast, dissemination protocols, such as Digital Video Broadcast (DVB), to encapsulate products of any format

• Dissemination is full and open, respecting existing data policies

- Data is divided into channels that user can select based on need

• The cost of satellite communications for each sector of the globe would be funded by one or more partners in GEO-NETCast, and the day to day management of each sector would be under their responsibility

Interface to GEO

• GEO, in December 2005, adopted the concept in principle of a GEO-NETCast, as presented by NOAA and EUMETSAT

• GEO-NETCast identified as key GEO Work Plan task for 2006

• GEO Architecture and Data Committee has oversight– Must coordinate also with Capacity Building and User Interface Committees

• GEO-NETCast Implementation Group (US/NOAA, EUMETSAT, WMO) leads and manages the initiative– Could include involvement of other infrastructure providers when identified

GEO-NETCast Implementation Group

• NOAA – Richard Fulton

• EUMETSAT – Michael Williams

• WMO – Donald Hinsman

• Other infrastructure contributors from around the world

Work for 2006• NOAA, EUMETSAT and WMO to refine initial technical details relating to late

spring demo of GEO-NETCast (as built upon EUMETCast), including the identification and provision by NOAA of data sets to be added to EUMETCast data. The first version of a demo product list is now available.

• Refine concept, including an assessment of current data transfer and dissemination systems, a discussion of options, and a recommended way forward, building on identified user requirements.

• Identify other GEO-NETCast providers to develop a global dissemination capability and all associated technical tasks.

• Work with the GEO User Interface and Capacity Building Committees and others to identify additional data, products, services, and reception requirements to address the needs of all nine societal benefit areas under GEO.

• Develop full master schedule through GEO-III timeframe.

• Report status and proposed way forward to GEO’s Architecture and Data Committee, Executive Committee, and Plenary.

Participants Meeting: July 19, 2006 Objectives with Outcomes

Objective: Ensure that there is a consensus understanding of the initiative;

Outcome:

– Scope of GEO-NETCast in context of GEOSS architecture

– Phased development, progressing to operational

– Global coverage

– Serving all nine societal benefit areas

– Involvement of developing countries

Objective: Identify those partners that might be able to provide other components, both infrastructure and data or products, contributing to a global dissemination capability;

Outcome:

- Prospective global coverage by late 2007:

- EUMETSAT currently covering Europe, Africa, much of Americas

- US/NOAA intending to provide coverage of the Americas and much of Pacific

- China offering to provide coverage of East Asia, Australia, and western Pacific

- Expanding data and products to serve all nine SBAs will require additional resources, both in-kind and actual (e.g., for additional bandwidth)

Prospective Chinese Contribution• China proposing its FengYunCast data dissemination

system to be an integrated component of GEO-NETCast– Moving from narrower Ku-band coverage to broader C-band

coverage (AsiaSat-4 at 122E)– 110 DVB-S user stations currently– Expanding number of stations this year to Bangladesh, Indonesia,

Iran, Mongolia, Pakistan, and Thailand– Currently focused mostly on transmission of meteorological satellite

data and products (FY-1, FY-2C, MTSAT, NOAA/POES, MODIS), but willing to expand to other types of data for all nine GEO societal benefit areas

• Russia testing MITRA satellite data dissemination system– They expect to propose it for GEO-NETCast

Participants Meeting: July 19, 2006 Objectives with Outcomes (continued)

Objective: Work with those participating as users to identify additional data, products, services, and reception requirements to meet the needs of all nine societal benefit areas under GEO;

Outcome: Importance of ongoing dialogue with User Interface Committee and Capacity Building Committee

Objective: Discuss the future framework of the 2007-2009 GEO Work Plan and any desired GEO-NETCast input;

Live GEO-NETCast Demonstration:Two Objectives:

• End User demo:– Demonstrate the real-time reception of GEO-NETCast demo

products using the 1.2m satellite dish here at the Boeing facility and our portable receiver station

• Data provider demo:– Demonstrate the ad-hoc transmission using internet FTP of a sample

product from Seattle to the satellite uplink facility in Germany, through 3 commercial satellites for broadcast and reception back here by our receive station

GEONETCast Demonstration Updates forGEO Meetings in Seattle

• A Ku-band, United States footprint from the AMC-3 satellite was set up by NOAA for the GEO Seattle meetings

• The purpose was to make the GEONETCast demo available in Seattle• A standard ‘DVB turnaround’ was implemented at the Americom

teleport in Alexandria, Virginia• This demonstrates:

– Implementation of a turnaround to extend the geographic coverage of GEONETCast;

– Data exchange by overlapping footprints (EUMETCast America feeds the AMC-3 retransmission).

2006-2007 U.S./NOAA Activities• Refine NOAA’s vision and concept for a GEO-NETCast in

the Americas– A draft NOAA document has been written and is being distributed for review

• Develop and approve NOAA’s Level 1 Requirements specifications and cost estimates

• Identify user product requirements• Engage other potential data providers regarding their

data/product size, frequency, etc.• Begin development of a data collection and dissemination

hub• Evaluate communication satellite provider services and
