184.2 NMEA Transmitted SentencesThe subsequent paragraphs define the sentences which can be transmitted on TXD1 by the GPS 35LPreceivers.4.2.1 Sentence Transmission RateSentences are transmitted with respect to the user selected baud rate.Regardless of the selected baud rate, the information transmitted by the GPS 35LP is referenced to theone-pulse-per-second output pulse immediately preceding the GPRMC sentence.The GPS 35LP will transmit each sentence (except where noted in particular transmitted sentencedescriptions) at a periodic rate based on the user selected baud rate and user selected output sentences.The sensor board will transmit the selected sentences contiguously. The contiguous transmission startsat a GPS second boundary. The length of the transmission can be determined by the following equationand tables:total characters to be transmittedlength = --------------------------------------------characters transmitted per secBaud characters_transmitted_per_sec300 30600 601200 1202400 2404800 4809600 96019200 1920Sentence max_charactersGPGGA 81GPGSA 66GPGSV 210GPRMC 74GPVTG 42PGRMB 26PGRME 35PGRMT 50PGRMV 32PGRMF 82LCGLL 44LCVTG 39The 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.The factory set defaults will result in a once per second transmission at the NMEA specificationtransmission rate of 4800 baud.
