- The dish receivers have to maintain coherence - which means
|
|
|
|
phase stability to an equivalent rms of 1 ps over time scales of
|
|
|
|
10-15 mins. This can be done by using go and return signals on
|
|
|
|
optical fibre. In addition time at the dishes and stations need
|
|
|
|
to be known to a few ns. The latter could be done by a network
|
|
|
|
of GPS receivers, NPT or White Rabbit. White Rabbit looks good
|
|
|
|
in terms of cost/performance.
