Yes, super-duper accurate timing. A nanosecond of timing error means your focal point moves by an angle equal to 1 foot divided by the distance between dishes.

Yes, super-duper accurate timing. A nanosecond of timing error means your focal point moves by an angle equal to 1 foot divided by the distance between dishes. You can calibrate out static timing errors, like due to different lengths of wire. But if the delay is varying for any reason your focal point will be slewing all over the heavens.
