Tips and questions relating to the GPS modules from SFE
By jjwhite
Anyone know how to get the Copernicus to output NEMA sentences faster than 1 second? I'm not finding a way to set that in the manual.

Unless overtly specified, most GPS units proved a once a second solution. This one appears to be your average 1 solution per second and hence one NEMA string per second.

It is just barely possible that if you switched to TSPI mode you might be able to request position data faster. But my guess is that your requests in the same second will yield the same results.
