EUM/OPS/VWG/13/705404ET-SUP 7 12 Data Dissemination & IGDDS 12

Charter Data & Product Dissemination

Charter data generated by the Charter Data Providers in support of the call will be disseminated via EUMETCast’s Disaster Channel;

These data will be available to Charter Project Managers to allow them to generate value added products in support of a call.

Products generated by the PM in support of the call would be transferred to the EUMETCast Disaster Channel for use by the Authorised or End user.

These products would be maps/imagery and other value added products for use by the disaster management agencies.

Overview

EUMETCast Evolution & DVB-S2


EUMETCast bandwidth evolution - past


EUMETCast bandwidth evolution - future


DVB-S2 Migration

Need for DVB-S2 migration

• Current transponder is more than 50% used by EUMETCast• Max for DVB-S is 29 Mbps net rate• Continuing DVB-S beyond 1 transponder is inefficient due to

• lack of free transponders• Price

• Migration schedule is driven by bandwidth needs and the status of the service contracts that underpin EUMETCast

DVB-S2 Migration


DVB-S2 Migration

Benefits of DVB-S2

• most effective and most flexible usage of a transponder´s resources, close to the known physical limits

• the provision of high throughput • the ability to shape the transponder usage depending on service

characteristics• due to flexibility in throughput the most cost effective usage of

transponder resources• secure the readiness of EUMETCast for upcoming missions


The future EUMETCast DVB-S2 based service

Two virtual services EUMETCast-Europe in the future:

• The Basic Service catering broadly for Nowcasting needs, addressing most Users, with focus on cheap commercial-of-the-shelf equipment and small antenna sizes;

Basic service: 8PSK 3/5, 44 Mbit/s net rate, 80 cm dish (footprint core)

• The High Volume Service catering for the NWP needs and broadly speaking for specialised users with focus on maximum volume dissemination;

High Volume service: 8PSK 9/10, 66 Mbit/s net rate, 1.8 m dish (footprint core)

• Both services can coexist on one transponder in any ratio. A scenario with a 50%-50% ratio was successfully tested for its technical feasibility with a full transponder in Feb. 2011. The link margin was higher than expected.


Transition to the EUMETCast DVB-S2 Service

Transition from current to new service• Parallel phase starting July 2014• Reuse of existing antennas will be possible• New DVB reception device needed (mandatory)

Following items are only known after selection of the new service providers:

• If different satellite is chosen, re-point reception antennas• Footprint changes are possible, some regions might require larger

antennas

High Volume service will be introduced at a later stage
