EUMETCast bandwidth evolution - past

EUMETCast bandwidth evolution - future


16/21



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


17/21



DVB-S2 Migration

Benefits of DVB-S2

most effective and most flexible usage of a transponders

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


18/21



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.


19/21



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
