[time-nuts] UBLOX LEA-5T Programming?

[Daniel Watson]

Hi,

The REF-0 will accept a PPS signal from a non-timing GPS. I use the u-blox NEO-6M for a lot of my testing. That module can be had in the $12 range online. I have also gotten the REF-0 to lock to a Venus GPS and an FE-5680B rubidium standard.

Of course, using a less stable PPS signal will give you less performance out of the REF-0.

I have some information about operating the REF-0 standalone documented on my blog:
