GPS Synchronized NTP Server Design (Stratum 1) with an Orange-Pi and a dedicated RTC Chip

Today will will take a look of the Design of a Stratum 1 GPS Synchronized NTP Server, I made a while ago for a Friend's Company, following Specs I received from The Customer:

a) 2 Ethernet Interfaces + Optional WiFi Port
b) Additional Battery Backed RTC Clock onboard
c) 5 Pcs Appliances Needed
d) GPS GNSS only Needed
e) Low Budget and fast Availability..
f) Integrated (Office Grade) Appliance no external parts except Antenna and Psu
g) Base Working Linux NTP System to be Adapted by the Software Department of the Customer

The Above Specs Determined the Design Decisions I explain in the Video for using a Orange Pi instead of a Raspberry Pi and PCB's a Front/Back panels instead of CNC Machined and Printed Aluminum ones..

Gerbers, Design Files and OS-System Image are Available on Demand.
Please bear in mind though, that due to the Higher HW Flexibility and OS Openness of my Design, my Build is more demanding in means of Electronics and Linux System know how.
