Rb Frequence Standard or a GPS disciplined for the home lab? Both is better

I found them somewhere, but now a quick search doesn't find them anywhere! :-// I must have dug them out of the Wayback Machine.
Here they are.

P.S. Datum created the LPRO. Later, Datum was bought up by Symmetricom.

Great, thanks, these I didn't find.

2nd Intermediate update:
GPS Antenna is on the roof - excellent receiving (min 5 sattelites, most the time 7 or 8).
Reworked the 24V DC power supply for the RB Reference - changed it from a linear to a DC/DC Buck Converter (XL4015 module).
System runs now a longterm test.
Next (and last) step is to 3D print a nice front plate.

3rd intermediate update:
After 1000 hrs non stop operation I change back from the DC/DC converter to the linear power supply.
The received need ~4x cycles to get the GPS looked. Also the lock is lost time to time, when number of visible sattelites is 5 ony.
Print 1st version of a front plate in white PLA. Not all holes fit perfectly (needd some manual correction).
My plan is to print a 2nd version in gray ABS.
