MKR GPS Shield library only works if you call GPS.Available() non-stop

If all it does is pull data, then it should work if you call it once per second as long as the chip has satellites fixed.

It can pull data when data is available.

Thus, if the GPS has data available at the moment you query the GPS unit at once a second, then the GPS unit will provide you with data. If, at the exact moment you query the GPS and it does not have data, then shrug.
