block to receive raw serial NMEA sentences from the GPS shield.Serial Receive

block is now configured to read raw NMEA sentences from the shield every 0.03 milliseconds. When the block receives 32 bytes of data from the GPS shield, the Status port outputs 1
, which in turn enables the $GPGGA_$GPRMC_Parser
subsystem. The $GPGGA_$GPRMC_Parser
subsystem contains the GPS Parser
block and the decoding algorithm.GPS Parser
block. This block is a custom block created using MATLAB System.Serial Receive
block using a decoding algorithm. The block outputs fields, such as status, time, latitude, longitude, and speed, from NMEA sentences.Outport

subsystem is enabled. If the subsystem is disabled, the block outputs 0
