Reading GPS MAVLINK output in Mission Planner

I’m trying to feed GPS data received by Mission Planner to a directional antenna for better tracking. I know through Mission Planner’s advanced functions I can get a live stream of data for NMEA and MAVLink messages. I’ve opened a COM port to see the data in real time, but this is what I’m seeing for NMEA.

And MAVLink.

From the character data, I can translate the NMEA script, but the MAVLink message is entirely lost on me. How can I parse the GPS data from MAVLink? How can I translate the NMEA datastream? Any help would be greatly appreciated.
