New EUMETCast Africa Service

The EUMETCast Africa Service will move from EUTELSAT 5 West to EUTELSAT 8 West. Parallel Broadcasts will run from May 2018 until July 2018.

The current satellite is approaching its end of life and a C-band service will no longer be available from the 5° location. The follow-on service will be provided from EUTELSAT 8 West starting in May 2018.

The purpose of this announcement is to provide details of the upcoming changes to allow a smooth transition of users to the new EUMETCast Africa Service.

The new service will be based on DVB-S2 to take advantage of the better spectral efficiency of the broadcast.

What hardware changes are needed to support the second transponder?

The new EUMETCast Africa Service will transmit using circular polarisation in C-band. Therefore, the existing feed and LNB can be used. The exact details will be provided soon.

It is strongly recommended that users point existing antennas following the latest EUMETCast, Satellite Antenna Pointing Guide (PDF, 774 KB)

The new service will use the DVB-S2 Transmission Standard — all users should check if their existing device is compatible with DVB-S2.

If your device is compatible with DVB-S2 and you are successfully receiving the current service, then it will also work under DVB-S2.

If the existing device supports only DVB-S then it must be upgraded. The devices compatible with the EUMETCast Europe service will also be compatible with EUMETCast Africa and are listed on the Reception Station Set-up web page.

What software changes are needed to support the new EUMETCast Africa Service?

Although the existing working version will continue to work, it is strongly recommended you use the latest Tellicast versions available from EUMETSAT. These versions are distributed via EUMETCast twice per day. Upgraded EUMETCast packages are also available as DVDs:

  • V2.14.1 rpm or debian or tar.gz for Linux
  • V 2.14.2_5 installer for Windows

The configuration changes will be described in the Tellicast installation guides, updated for the new C-Band service.

What PC hardware change is needed to support the new EUMETCast Africa Service?

No PC hardware changes are necessary to continue receiving the current selection of products on the new service. Users who want to receive new services might want to upgrade their hardware to keep up with the growing data rates.
