Time Server
-
I have been asked to locate a device to be our corporate time server. We want a device that preferably does not require an exterior antenna and that can be rack mounted. We do not want a build your own, such as a Pi and GPS receiver. The device must work in the US, Europe and Asia.
For internal reasons we do not want to get time from the internet.

@AndyRH we have used these in corp setups before

You are going to need an external antenna.
There are a number of devices that will work world-wide. FWIW, my favorites are the LeoNTP units, which are quite good and relatively in-expensive.
The current model, the LeoNTP LBE-1200, is usually within 100ns, with a standard deviation of <25ns. Very stable. It isn't large enough to require rack mounting, however there is a rack mount kit available for it. They are PoE or USB powered, so worldwide operation is not an issue.

The no antenna part is a hope or a dream. It would make installation easier.
Have you tried using it with the antenna inside a building? I checked the GPS quality on my phone it is better than I expected. I am sure the phone's antenna is not of good quality. -

Yes. The puck antennas generally work okay depending on construction and surrounding buildings, but you'll have to test each location. A roof mounted antenna is highly preferable if you can, especially in dense urban areas.
Edit: Btw, a big advantage of a PoE unit is that you can position it closer to good reception.

@dennypage PoE is definitely on our feature list.
