NMEA Checksum Calculator

UNIMAX NCC-22 NMEA Checksum Calculator

NMEA Checksum Calculator, calculates the checksum of NMEA sentences not including checksums and sends them to the output. In some older marine navigation devices, NMEA data is sent without calculating the checksum. New devices do not accept data without checksum.
