OCXO with ADEV of 1E-13 on Pluto Mission

[Mr Smiley]

From the 'time-nuts' mailing list

*********************

Here is an interesting link to the New Horizons Mission to Pluto radio
system design.
Note last section describes an OCXO with ADEV = 1E-13 at 1s, and aging rate
of <1E-11 per day.

I wonder if their spares will show up on eBay?

The link below is an updated version of the same paper:

http://www.boulder.swri.edu/~tcase/NH%20RF%20Telecom%20Sys%20ID1369%20FINAL_Deboy.pdf

It has considerably more detail on the RF components as well as the
USO module for which there is an entire page of additional information
and a block diagram.

Whatever happened to the spare components probably happened a decade
ago at any rate. Not that they wouldn't eventually wind their way to
ebay anyway!
