[time-nuts] GPS for Nixie Clock

[John Swenson]

I take it the "T" is a time specific version, I see there is also a NEO 
M8T, I presume this include the position hold etc?

This:

Seems like an interesting board with a NEO-M8T, a UF.L antenna 
connector. The little breakout board gives a direct USB interface as 
well as timing signals. With the USB it looks like it should work with 
the U-center software for evaluation and configuration which would 
probably make it easier to get going.

Does this seem like a reasonable board to get?

Thanks,

John S.

If you do have problems getting a signal it can be very difficult to add an external antenna.   You might want to try moving one around the house and seeing how well it works.   It usually takes an indoor GPS a while to acquire lock to the GPS satellites.

Normally an LEA-6T GPS receiver is over $100...   But to get the full benefit of a GPS timing receiver requires quite a bit of configuration and setup.

Mine is currently tracking 25 satellites (GPS/GLONASS/SBAS) with an indoor antenna.  It cost around $25 and came with a removable antenna.  It has two programmable PPS outputs (only one is brought out to the connector)... you can set one to 10 KHz.
