Planck

15th May 2009 Planck received at virtually the same az/el as Herschel, even with local tree clutter. Downlink frequency was 8468.454MHz, the FFT below shows the tail end of a coherent locking cycle. The distance to the probe is only ~170,000 Miles. The FFT's below are from the IF frequency, add 8GHz to get the receive frequency.
