| This is an optional offering. Once deployed, users are responsible for its maintenance and updates. Feel free to ask for feedback in the #peer-support channel on EWC RocketChat. |
EUMETCast is EUMETSAT’s primary dissemination mechanism for the near-real-time delivery of satellite data. EUMETCast serves data through two complementary delivery systems: EUMETCast Satellite and EUMETCast Terrestrial.
Terrestrial services for data distribution, available and supported, include:
Additional terrestrial services for data distribution will be created in the future for various missions. If unsure of which services your credentials grant you access to, please contact the EUMETSAT User Helpdesk (ops@eumetsat.int). |
| Terrestrial Service | Total Bandwidth (Mbps) | Data | Default |
|---|---|---|---|
| ter-1 | 240 | EPS, MSG, Sentinel-3A/B, Sentinel-5P, Third Party data, MTG | yes |
| ter-2 | 168 | Sentinel-6 data | |
| ter-3 | 230 | Sentinel-5P L1B, Sentinel-3A/B OLCI L1 FR, Sentinel-3A/B SLSTR L1B, FY3 HIRAS, FY4 GIIRS, GOSAT, MTG HRFI-FD (4 high-res full-disk bands) |
If provisioning after October of 2025, we recommend deploying based on the community hub, to benefit form upcoming features or fixes. |
Upon completion of the above steps, you should have the following credentials at hand:
| Name | Description |
|---|---|
| username | Tellicast license user identifier, Equivalent to your EUMETSAT User Portal username. |
| userkey | Tellicast license activation key (i.e. the user key you obtained via from EUMETSAT Helpdesk). |
You may create security groups either via Morpheus UI settings OR via Community Hub Item deployment. |
Create a designated security group with a descriptive name (e.g. "eumetcast" ) and add to it the following rules:
| Name | Direction | Rule Type | Protocol | Port Range | Source Type | Source | Destination Type | Destination Port Range |
|---|---|---|---|---|---|---|---|---|
| 2268-udp | ingress | Custom Rule | TCP | 2268 | Network | 0.0.0.0/0 | Instance | |
| 8500-tcp | ingress | Custom Rule | TCP | 8500 | Network | 0.0.0.0/0 | Instance |
A security group for ssh access should exist in your tenancy by default. Simply verify it is available and enforcing the following rules:
| Name | Direction | Rule Type | Protocol | Port Range | Source Type | Source | Destination Type | Destination Port Range |
|---|---|---|---|---|---|---|---|---|
| 22-tcp | ingress | Custom Rule | TCP | 22 | Network | 0.0.0.0/0 | Instance |
Checkout the corresponding Community Hub Item.
This method of deployment is deprecated, and kept in documentation only as reference for EUMETSAT tenancies that relied on it prior to October of 2025. |
2. Use the search bar to find the 'EUMETCAST TERRESTRIAL ON AMT' (type eumetcast or terrestrial for example):
3. Select name for your VM (e.g. eumetcast-client)
4. Use the following specifications for the provisioning of the client:
Resource | Recommendation |
CPU | 8 cores |
RAM | 64 GB |
OS | Ubuntu v 22.04 |
Storage | 1.2TB |
EWC Plan | hm.xlarge |
Note that by default, none of the available VM plans offer you 1.2 TB of storage. In order to reserve said amount of storage, you must attach an additional volume to your VM and specify the desired size:
5. Insert your Tellicast license credentials
6. Select the following security group:
7. Select the floating IP as external
8. Hit Next and Complete to create the VM
9. (Optional) Improve file availability through retransmission by enabling retransmission feedback ( see Morpheus Legacy: How to enable NAKs for EUMETCast Terrestrial on AMT and Morpheus Legacy: How to enable ACKs for EUMETCast Terrestrial on AMT for details)
11. (Optional) Enable ssh access to the VM, by browsing the Morpheus UI to your eumetcast VM → Network → Security Group → Edit Security Group → add ssh.
12. (Optional) Note that all data is deleted 5 minutes after retrieval by default, to prevent the build-up of data on the machine. To learn how you can modify this behavior, checkout EUMETCast Terrestrial on AMT - How to modify the time to live of the data.
Once the service is provisioned, the user will start to receive their subscribed data on their VM (stored by default in /root/data/eumetcast/ but can be changed in the /etc/cast-client-channels_ter-1.ini file).
To access the User Notification Service (UNS), go to uns.eumetsat.int. You can find information on service alerts, scheduled maintenance and service enhancements. You can subscribe to UNS email notifications via the Earth Observation Portal. In addition, users can receive regular updates on scheduled maintenance and service enhancements through our EUMETSAT Users Twitter feed.
Full documentation specific to EUMETCast Terrestrial can be found on the EUMETSAT website.
