All data (POSITION, BTW, SOG/COG, etc.) is received from one type of NMEA
sentence. If data is placed in different locations, the data will be selected from the
sentence with the highest priority.

Example II: BTW/DTW is priority first with: RMB, BWC and BWR.
The transmission ID (the first two letters after “$”) is ignored by the Server.
