Hi sorry for a possibly OT post.
Has anyone had practical experience with small commercially available time
servers / ntp servers suitable for mobile use in a vehicle.
The use case is I am in need of an accurate (ie. within 100 ms) time source
for several pc's in moving vehicle. Being able to run directly off a 13.8
or 28 VDC source would be a major plus but AC power is also available.
Hold over if there are gaps in GPS coverage is also a major plus.
We already have a GPS with a 1 pps output, but an integrated box with it's
own GPS would be best.
Yes I am aware I could feed a 1 pps signal into a laptop and use that as a
time server and I may end up going that route.
There is a small Ethernet LAN in the vehicle. The pc's currently get their
time via a wireless connection to various NTP servers. I need to be able
to ensure accurate time on the PC's if there is no wireless coverage.
This is for a one off project so piecing together various parts is an option
but a single box COTS solution would be nice. I've found a few candidates
via web searches but would welcome any feed back.
Thanks in advance
Mark Spencer
