I see that Mark Sims examined this Navicom GPSDO in March 2019 (EEVblog).

Surplus Navicom RCGD-M units have recently appeared on eBay,
https://www.ebay.com/itm/312306372323
from reseller ?EYT_GPS? (Shenzhen, China).  Lady Heather (used by reseller) identifies Navicom GPS receiver as Motorola (looks like Oncore footprint).
A bit of a mystery to the reseller, outputs/inputs to the FGPA on boards.
Tight, stacked assembly.

He has another unit, (cheaper) that uses the Furuno GT-8031F  GPS receiver module and an unknown OCXO.
