Re: [Discuss-gnuradio] radio astronomy fast radio burst help requested

What would it take to get phase coherency, say at 1 GHz, on a global scale;
short of running cables? I assume with a moderate priced GPSDO one can get
10E-12 stability, so that would be 0.01 Hz frequency stability at 1 GHz.
Does that mean you can integrate for 10 seconds and stay within 0.1 radian
phase drift?
