Re: SBC hardware for stratum 0

[Frank Nicholas]

U-Blox is a manufacturer of the current most popular (I think) GPS chipsets...  
They are are inexpensive, generally available from many sources, but are 
some-what proprietary with their specs/protocol (but they do support NEMA 
standard, semi, based on the standard/version with proper configuration of the 
board/chip).  GPSd supports them generally very well, but with their 
proprietary nature & ever-changing specs, sometimes it makes it a challenge for 
open source projects to keep up or completely interpret/support them in their 
proprietary binary config (binary generally being better than NEMA) vs. NEMA, 
especially with various version/firmwares.

Others may have additional opinions or information.  The is my personal 
understanding & observations from following this list & personal research.

Thanks,
Frank
