[time-nuts] Noob question, NTP stratum 1.

[David J Taylor]

From: wildylion via time-nuts

Hello there,

I wanted to ask for advice regarding NTP

Situation 1:
What I currently have is a uBlox M8N GPS puck I'm planning to use with the 
Raspberry PI. Seems like it should work almost out of the box with some 
kernel tuning, but I have a question about short term stability in the event 
of GPS loss - how well will the board hold over if it's lost GPS for, say, 
24 hours?
[]
Maybe BG7TBL's units instead of LeoNTP?
Is that a good idea?
=======================================================

I would not rely on e.g. a Raspberry Pi for good short-term timekeeping!

Different beasts!  The LeoNTP is a complete unit, providing a precise NTP 
source out of the box.  It can be powered over its Ethernet connection as 
well.  No other computer is required.  Holder over is specified as: 
"Typically 1-4ms in 24 hours.  Reverts to Stratum 16 after 24 hours with no 
GPS".

Cheers,
David
