Decoding NIST WWVB signals with LabVIEW

Message contains a hyperlink

Hi All,

 

I was wondering if anyone had code for decoding the NIST WWVB signal from CO.  Wikipedia: http://en.wikipedia.org/wiki/WWVB

 

Sometimes this is incorrectly referred to as the atomic clock.

 

Since this is fairly old I figured there would be something on the forums but to my surprise nothing I could find.

 

This is for a specific application where I need a very low cost timing signal outside.  I have a receiver outputting the signal shown in the Wikipedia link above and access to LabVIEW I/O input DAQ, CRIO, sbRIO etc.

 

Regards,

 

-SS

Hi Simon,

 

I've been doing some digging, and was fairly surprised when I also came up empty-handed.  That being said, I think the simplest way to implement this would be to call a DLL using the call library function node.  If you do end up building this in LabVIEW, I'm sure that it would be well received on the developer community.

Interesting project!

 

I looks like a few people have tackled decoding the data (both WWV and WWVB) using reciever modules that create a digital signal stream and Arduinos to decode the data.

 

How about GPS based time? Here is reciever/decoder module that provides a decoded serial data stream:
