RAFS clocks In recent months, a total of three RAFS clocks unexpectedly failed on Galileo satellites — all on Full Operational Capability (FOC) satellites, the latest Galileo model. These failures all ...

Orolia’s atomic clock solutions have been selected for the Galileo Global Navigation Satellite System (GNSS) under contracts totaling 26 million euros for an additional 12 Galileo satellites. This ...

Orolia’s RAFS is an ultra-stable rubidium atomic clock able to deliver a frequency stability of about 2 x 10 -14 over averaging intervals of 10,000 seconds. The Leonardo PHM, with its excellent ...

Each orbiter needs one working clock for the satellite navigation to work, with the other three clocks being spares. As of mid-January, 10 Galileo atomic clocks, the key element in a navigation ...

The onboard atomic clocks that drive the satellite-navigation signals on Europe's Galileo network have been failing at an alarming rate. Across the 18 satellites now in orbit, nine clocks have ...

Galileo sensor stations, reversing the way satellite navigation usually operates, work together to pinpoint a Galileo satellite’s orbital position, its clock rate and signal health.

Orolia, a resilient positioning, navigation and timing solutions company in France, has secured €70 million in atomic clock contracts that will help keep the Galileo Second Generation system ...

The European Union Agency for the Space Programme (EUSPA) has officially declared its Galileo Open Service Navigation Message ...

Still operational Each Galileo satellite carries two rubidium and two hydrogen maser clocks. The multiple installation enables a satellite to keep working after an initial failure.
