At least 20 years for the imagery mission and 15.5 years for the sounding mission will be secured through operations of the MTG satellites.
Three in-orbit satellites are needed to deliver the full complement of services. This includes a prime 0 degree MTG-I satellite, a second MTG-I satellite (acting as in-orbit hot backup for the prime MTG-I satellite and supporting the RSS services) and an MTG-S satellite.
To span the operational life time of the programme there will be four satellites dedicated to support the imagery missions (MTG-I), and two satellites to support the sounding missions (MTG-S).
Each satellite is specified for a nominal lifetime (including commissioning) of around 8.5 years, carrying the payload complements or meteorological sensors according to the following split:
- MTG-I: FCI, LI, DCS and SAR
- MTG-S: IRS + UVN (GMES S-4)
Progressive deployment of MTG services
For service continuity an overlap between the MSG satellites delivering the heritage operational services and MTG is planned.
During the comissioning phase the new MTG services will be implemented in parallel to the heritage services provided by the MSG satellites. During the initial MTG operations phase, the heritage services on MSG satellites will be provided in parallel. The full operational capability will see the MTG satellites providing all planned services.

Meteosat services in the MTG era
Once in operations, MTG will gradually replace the MSG services.
