Hi It's not the best thing to use. Since the 10 KHz jumps once a second, it's not really very useful. The GPS it's self is not as well optimized for timing applications as a UT or a LEA-(any number) T. At auction prices, the GPS isn't going to be the major cost item in your GPSDO. Better to

Hi Bill, I have a number of these modules purchased from the particular eBay source you gave a link for. They work well but I never found a way to keep their data output as NMEA as they seem to revert to Binary on power down. However if it is just the 10KHz output you want from them or

If you ned the 10KHz, Jupiter is one that has been used. I think a 10KHz GPS will make your GPSDO converge quickly but for long term use a 1Hz GPS works as well and will be easier t replace years from now. Also a 1HZ GPS with about equivalent performance is MUCH less expensive (see ebay
