This could be interesting.
The u-blox does a fantastic job if you ask me.
Does this gps provide better or more stable signal compare to the u-blox modules?
This BCM47755 is the Third-Generation GNSS Broadcom chip and I think if it would interesting for the developers they already would have implement it.
Although it looks cool for many other GPS related projects.
I believe this is the first cheap/mass-market chip that does dual frequencies? So much better multi-path rejection and accuracy.
