Given the availability of the Ublox GPS-RTK chips, I'm thinking of replacing my GPS subsystem connected to Teensy 3.2 and 3.5 devices. Do you think your library will hold up? I doubt you thought about position corrections data input back in '16. But, hey, you never know.

Sparkfun has an Arduino library to work with their boards, and I'll test that with the Teensy's. There likely will be one or two issues. But would love your thoughts, if you have any.
