[time-nuts] FS Rb track/hold was [Re: GPS jamming susceptibility]

[Christophe Huygens]

On that subject, I have a Symmetricom chassis for sale with Rb track/hold
(dual PRC inputs I believe, with room for a second holdover card,
dual power supply, and 16 2048Khz outputs - more reduncancy than you
would want).
Can go at time-nut price before it goes on auction.
+ ship from 3000 BE.

Manual included, tested good.

Thanks,
Xtof.

There are simply to many things that can create issues with the signal you are using. That's true of any over the air system, not just GPS. Redundancy would also be nice, the people who design these systems don't seem to ever go that route.
