Calculate a NMEA 0183 checksum for the given sentence NMEA checksums are a simple XOR of all the characters in the sentence between the leading "$" symbol, and the "*" checksum separator. >>> calc_checksum("$GPGGA,142058,5308.6414,N,00300.9257,W,1,04,5.6,1374.6,M,34.5,M,,*6B") 107 >>> calc_checksum("GPGGA,142058,5308.6414,N,00300.9257,W,1,04,5.6,1374.6,M,34.5,M,,*6B") 107 >>> calc_checksum("$GPGGA,142058,5308.6414,N,00300.9257,W,1,04,5.6,1374.6,M,34.5,M,,") 107 >>> calc_checksum("GPGGA,142058,5308.6414,N,00300.9257,W,1,04,5.6,1374.6,M,34.5,M,,") 107

Generate a NMEA-formatted latitude pair >>> nmea_latitude(53.144023333333337) ('5308.6414', 'N')
|
Generate a NMEA-formatted longitude pair >>> nmea_longitude(-3.0154283333333334) ('00300.9257', 'W')
|
Parse a NMEA-formatted latitude pair >>> parse_latitude("5308.6414", "N") 53.144023333333337
|
Parse a NMEA-formatted longitude pair >>> parse_longitude("00300.9257", "W") -3.0154283333333334
