Transponder parameters

(Latest information as of 17 March 2021, this supersedes the information given in TD 15.)

In case of an unrecoverable failure of EUTELSAT 10A the EUMETCast Services will be continued on EUTELSAT HB13 in the 13° East orbital position. The downlink parameters are listed in Table 2. Should the downlink parameters be changed (e.g. for a different transponder) the changes will be reflected here.

Use of the backup satellite

The backup satellite will be used only in a case of emergency, i.e. when the prime satellite E10A cannot provide the service due to a permanent failure. In this case, EUMETSAT will inform the users (via our User Notification Service: https://uns.eumetsat.int/) that EUMETCast Europe is provided by HB13 and users will then need to reconfigure their antennas and receivers for the transponders 6 and 8 on HB13.

It is recommended that users prepare their reception systems for the backup satellite and transponders, in order to keep the interruption to a minimum, should the backup satellite be activated. There are two choices available for the out-door equipment:

  1. Set up a separate reception chain for HB13. Follow the satellite dish alignment section to point the antenna.

  2. Set up a multi-feed solution according to the Ku-band dual feed guide.

Spare DVB receivers can also be prepared:

  • Configure the first receiver for E10A, transponder 1 (C4)

  • Change Downlink frequency, or L-band frequency to the value for 13C 6 (see Table 2)

  • Change Polarisation to vertical

  • Configure the second receiver for E10A, transponder 2 (C10)

  • Change Polarisation to vertical

  • Change Downlink frequency, or L-band frequency to the value for 13C 8 (see Table 2)

The spare receivers can be left in cold standby (off), warm standby (on, but disconnected), or even hot standby (traffic connected to the operational network). If in hot standby, reception will automatically start in case of a backup activation.

  • All other users will have to adjust their existing antennas once they are informed that HB13 is activated:

  • Change Downlink (or L-band) frequency for transponder 1 to the value for 13C 6 (see Table 2)

  • Change Polarisation to vertical

  • Change Downlink (or L-band) frequency for transponder 2 to the value for 13C 8 (see Table 2)

  • Change Polarisation to vertical

  • Repoint the existing antenna to HB13 (azimuth first)

  • Optimise pointing by maximising link margin, EsNo or C/N
