General
| 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) |
Note: Additional terrestrial services will be created in the future for various missions. If unsure of what services you need to enable on your station, please contact the EUMETSAT User Helpdesk (ops@eumetsat.int).
- Update user subscription in EO Portal
- Log into Reception station (e.g. ssh into it)
- Open the file called
tellicast-client.cfg
vi /etc/tellicast-client.cfg
4. Update the following parameter and save the file.
INSTANCE_START_ORDER=ter-1,ter-2
5. Open the file called cast-client_ter-2.ini
vi /etc/cast-client_ter-2.ini
6. Add credentials and tunnel IP to ter-2 configuration file and save the file
user_name=<username> user_key=<password> interface_address=10.0.0.11
7. OPTIONAL: Update storage path for new data, modifying cast-client-channels_ter-2.ini file (See also How to change file storage path)
vi /etc/cast-client-channels_ter-2.ini
8. OPTIONAL: Configure IP for NAKs (if enabled) using the following commands (See also How to enable NAKs)
iptables -t nat -A POSTROUTING --destination 193.17.9.7/32 -j SNAT --to-source <internal-IP of station>
iptables -t nat –L
Ensure the rule persists after reboot by saving the iptables rules:
sudo apt-get install iptables-persistent
iptables-save > /etc/iptables/rules.v4
9. Restart tellicast client software
sudo systemctl restart tellicast-client
Log entries for each terrestrial service can be found in /var/log/tellicast-client/recv_ter-x.log where x indicates the service, i.e. /var/log/tellicast-client/recv_ter-1.log for ter-1 service.
Terrestrial Service Ter 3 (NEW)
EUMETCast Terrestrial will undergo reorganisation on 11 September 2023. This change is intended to optimise the bandwidth usage on the EUMETCast Terrestrial service.
The announcement channel for TER-3 (232.223.224.1:4711, source 193.17.9.4) is now active. Users now launch the new TER-3 instance on their reception station, as specified in the announcement.
A new EUMETCast Terrestrial instance (TER-3) will be created to disseminate data that is exclusively available on EUMETCast Terrestrial and not on EUMETCast Satellite.
For more information you can refer to the official page from EUMETCast team: https://eumetsatspace.atlassian.net/wiki/spaces/DSEC/pages/1989640193/EUMETCast+Terrestrial+Re-organisation
For users using EUMETCast Terrestrial on the EWC prior to the 11 of September
Users in the EWC with existing EUMETCast Terrestrial machines can include the new service in the following ways:
OPTION 1: Add configuration files to existing machine
Add the configuration files for TER-3 as described in the table below:
| configuration file name | configuration file | location in your machine |
|---|---|---|
| cast-client-channels_ter-3 | cast-client-channels_ter-3.ini | /etc |
| cast-client_ter-3 | cast-client_ter-3.ini | /etc |
OPTION 2: Redeploy a new machine from Morpheus
