TRANSMITTED NMEA 0183 SENTENCES
The subsequent paragraphs define the sentences that can be transmitted on COM 1 by the GPS sensor.
3.2.1 Sentence Transmission Rate
The GPS sensor will transmit each sentence (except where noted in particular transmitted sentence
descriptions) at a one-second rate. The GPS sensor will transmit the following sentences contiguously. The
contiguous transmission starts at a GPS second boundary. The information transmitted by the GPS sensor
is referenced to the GPS second boundary immediately preceding the GPRMC sentence.

The maximum number of fields allowed in a single sentence is 82 characters including delimiters. Values
in the table include the sentence start delimiter character “$” and the termination delimiter <CR><LF>.
The factory set defaults will result in a once per second transmission at the NMEA 0183 specification
transmission rate of 4800 baud.
