Re: [AFMUG] GPS'd NTP

2017-09-07 Thread George Skorup 
Yes, their eNB has an on-board GPS and the kit includes an external 
active antenna. 1588v2 is also supported. We've had some issues with the 
GPS on a couple. Could be weird reflection/multipath issues or the 
receiver going stupid. Haven't figured it out yet. Sometimes a reboot 
will cure it if they lose lock. Got one that's a consistent pain in the 
ass. We'll probably end up swapping that one to rule out a receiver issue.

A GPS+GLONASS SBJ basic and USB kit would be pretty cool. Could
the USB interface also power the box, up to say 20-25 feet? The
other thing is, all of the machines I'm working with have a serial
port. So maybe just skip the USB altogether?

I was thinking, maybe take the daisy-chain output from a
SyncInjector/PowerInjector/RackInjector since those switch the
pipe/box to NMEA anyway, but I don't think I'd want a path from
the tower-mounted gear to server(s). And other funky stuff like
noise making it into the timing for the radios would be ungood.

Re: [AFMUG] GPS'd NTP

2017-09-06 Thread Forrest Christian (List Account) 
My rough draft here is a USB-serial interface with an isolated DC-DC
converter and a isolated usb-serial interface, so you are at least mostly
electrically and opto isolated from the SBJ.   Plug into a USB and then
power the SBJT.   So USB to a small box, then cat5 to the SBJ.  This is a
small enough and fun project that it will probably just happen and fairly
quickly - I need a few of these after the nightmare of the rackinjector
(think of it as a working vacation).

I've also had on the todo a NTP all in one appliance, probably in the SBJ
or SB12 box.   That same code would make it into the rackinjector and any
followon similar products.   There are quite a few things ahead of it on
the roadmap though...

As matter of fact I picked up a raspberrypi + gps receiver last week to start 
building a strat-1 ntp server for my network. My plan is to build 1-2 of these 
and use them to feed a couple of traditional servers that the rest of the 
equipment poll's.

This is what I ordered:

https://smile.amazon.com/gp/product/B010Q57SEE
https://smile.amazon.com/gp/product/B00I6LZW4O

Haven't had the time to actually put it together yet though, but there are 
plenty of resources available online on how to get it working.

I just have a Mikrotik as NTP server and have it use time.apple.com or
time.google.com as a parent.

If you have an old canopy CMM it has a GPS receiver and can act as NTP server.

Subject: [AFMUG] GPS'd NTP

I've got a few CentOS machines running around the network doing various
tasks, one being NTP for radios, routers, switches, etc. I've been
having some issues with us.pool.ntp.org lately. I switched to
time-(a,b,c,d).nist.gov. Apparently those are pretty busy.

So is anyone else using GPS to feed NTPd? From what I've been reading, I
guess I need a 1PPS capable receiver. Does that exist in a simple USB
package? That would be ideal, preferably with an SMA female for an
external antenna where needed. Looks like none of the cheap shit I'm
finding on Amazon has PPS output.

I'm pretty sure the one I looked at used the GPS receiver in the cell modem to 
supply the time vs. CDMA.

Well, yeah, you can do CDMA for clock sync, too. 

I've seen Arduino and Pi add-on cards that contain a GPS receiver and you 
basically feed the 1PPS via GPIO or something like that. I don't really want to 
go there. 

I'll keep looking around and see what I can find for standard-ish PC hardware.

I could tell you how to wire a syncbox junior up to a usb port if you'd
like.  Requires a TTL level usb to serial cable.

I'd you wait a month or so until the gps+glonass version is out it well
even speak nmea.  Heck,  now I think about this it might make a good
product  syncbox basic plus a USB dongle.

Pretty sure you're thinking of LMG CTMs that would lock up due to NTP 
request overload. I think they found it was counterfeit RAM causing most 
of those problems...?

I'm not sure about the modern CMMx

I have installed several GPS repeaters for some manufacturing plants that
use them to test GPS enabled avionic devices but side benefits have
improved cellular routers with GPS and LTE devices.
