One way time transfer via Meteosat capable of 30 (ns accuracy

The METEOSAT ranging signal's available every 3 hours for about 1.5 minutes, its phase is measured against the second pulses of the station clocks. A system study shows that the accuracy obtainable could be in the order of 30 ns. The receiver unit consists of a 2 m diameter fixed antenna, a low noise broadband receiver, and a phase tracker and demodulator. The overall costs will be less than $20.000 US.
