In my case, a GPS disciplined oscillator. There are a number of these floating around on eBay. The one I selected is the Trimble Thunderbolt, because I know one of the firmware engineers that worked on it. There is also a FB program called, "Lady Heather's Disciplined Oscillator Control Program" which allows you to monitor the Thunderbolt's operation. Trimble also has a program posted on their website, used for Thunderbolt configuration/set up, and status monitoring.
