This exact sentence lack enough details to be not understandable. What
GPS receiver are you talking about? The one inside the FR? It is
already connected via the serial port to the SoC, you can not change
that without hardware hacking. And it supports both NMEA and u-blox
protocols btw. And what is the problem with accessing it? fso-gpsd
uses a well-established interface and is usind ogpsd to gather the
data (ogpsd connects to the serial and does u-blox communication with
the receiver). Etc...
