NMEA output more Data than just GPS

Currently mission planner can only output NMEA GPS data but what would be very useful would be the ability for it to output other NMEA type sensors like:

Rangefinder/depth sounder
Temperature
Water speed
Wind speed and direction
AIS
it would let mission planner interface with marine equipment much easier, All of this is available in mission planner so it would just need converted to NMEA.

Start by locating Mission Planner’s existing NMEA GPS output path and comparing it with the sensor data already available in Mission Planner. Review the linked discussion for marine-use context, then define the supported NMEA mappings for rangefinder, temperature, water speed, wind, and AIS and identify how each output can be verified.
