Hi,

It's not totally clear from your description which 'Copernicus' GPS module you are using, so I took a look at the datasheets for a number of these modules sold by SparkFun. The 'PPS' output signal on all the Copernicus GPS modules is very short at about 5uS (microseconds). It only repeated once per second, so I'd say that it's probably there, and you're just missing it!

What kind of scope are you using? Is it a 'traditional' oscilloscope, or one the 'Nano' pocket-size units?
