Hi A number of us have Trimble TBolt’s that have been running for over 10 years. The early HP’s (Z3801 … ) seem to have a weakness in the power supply section. So far mine have come back to life after simple repairs. That puts the into the 20+ year range. The “Nortel” GPSDO’s seem to just keep on running and running.
That’s just looking at the devices that have been out there long enough / in big enough quantities to look at “longevity”. It is by no means trying to say those parts are any more reliable than others. Simple answer is that a GPSDO is a pretty simple beast. You have a GPS module of some sort. They seem to last a long time. You also have an OCXO, 20+ years is a reasonable expectation on a modern part. There nothing like the Cs tube to “wear out”.
