Virtually every GPS USB receiver uses a USB-to-serial-bridge. Virtually
every known one is supported by NetBSD.

So, your software just has to deal with a serial line (/dev/ttyUX).
Plugging the hardware into your system should tell that to you,
given you have configured the required USB stuff into your kernel.

Just use 8N1@4800 baud and read the NMEA data as pure text should
do the trick.
