Baud Rate 4800 Parity None Data Bits 8 Stop Bits 1 Handshake None

The document describes the serial configuration and data formats for two common NMEA-0183 data sentences: 1) The GGA sentence specifies the time, position, and fix related data with fields for latitude, longitude, GPS quality indicator, number of satellites, and more. 2) The RMC sentence contains recommended minimum specific navigation information with fields like status, latitude, longitude, speed over ground, track made good, date, and magnetic variation. The configuration is set to 4800 baud rate, no parity, 8 data bits, and 1 stop bit with no hardware handshake.
