Re: GPS Time Reference

For a low cost option have a look at the kits from  https://www.qrp-labs.com/

They have many interesting units for GNSS, clocks and synthetic crystals etc.

Hi Neil

Do you have a Trademe auction number?

I am currently looking down the DIY lab frequency standard rabbit hole and it is looking a lot deeper than $40.

It looks like many of the Aliexpress U-Blox Neo gps modules are probably fake and gps based time has high phase noise.

The cheap fake gps modules would be just fine for running slaves or comparing against a master.

Hi Darren,
                     there is a chap in the SI who makes and sells such a unit on Trademe for $40. It has a GPS receiver and a nice little LCD display showing the GPS lat & Long and the time in HHMMSS all for $40.

Hi

I have been looking at using a GPS receiver to use as reference time for a RF signal generator upgrade.

I have also been working on developing a arduino based controller  that will drive both a Solari Udine Cifra 12 and Synchronome slave clocks from a Synchronome master.

It would not be difficult to add a GPS receiver to the Arduino controller that would either replace the Master or accurately measure the Master error.

My plan was to make just one controller for me but I thought perhaps others might want one.  Is that something anyone else would like to own?
