I’ve now updated the scripts to support:
* Receiving GGA/HDT sentences from UDP or serial and send to Underwater GPS to use as reference system (nmeainput.py). Eg: using a high quality GPS/Heading source to improve position accuracy.
* Sending the underwater position / Locator position as GGA sentences over UDP or serial (nmeaoutput.py). Eg: using the Underwater GPS position in a chartplotter.
