The agency schedules delivery of the four spacecraft for 2031, with launches afterwards. This is an order, not additional satellites already in orbit. ESA says the first spacecraft of the new generation are due for integration and flight testing in 2027 before an initial launch planned for 2028.

Announced equipment includes digital navigation payloads, improved antennas, inter-satellite links and an advanced atomic clock configuration. These are intended to strengthen positioning, navigation and timing services.

Thales Alenia Space says its two additional spacecraft will be integrated and tested in Rome. The timetable remains an announced programme schedule, with neither delivery nor launch confirmed at this stage.
