We're looking for a good GPS receiver clock that has:
- an RS-232 output
- a 1 pulse-per-second output
- can output GPS time (similar to UTC but no leap seconds)
additional nice features would be:
- an ovenized internal oscillator (in case our antenna is struck by
lightning)
- as few controls as possible (less to get screwed up by button-pushers)
- rack mount

So far the best bet appears to be a $4000 model from Datum, the 9390-5200.
It seems to do everything we want and has no front panel controls at all!

We have also looked at offerings from Odetics and TrueTime. The Odetics
clocks would be the best bet, but they cannot output GPS time. TrueTime has
quite a variety of clocks, but at present no cheap simple clocks (though
some are due out shortly--not rack-mount).

So...has anyone used a clock from Datum, Inc.? Did you like it? Any
comments on TrueTime or other alternative companies? Note: I have already
read the excellent file pub/ntp/doc/clocks.txt from louie.udel.edu.

I will summarize any e-mail responses. Any help or advice would be most
appreciated.
