• The return value is a 4-byte wide value that stores latitude similarly to NMEA text format “ddMM.mmmm,N|S” (NMEA requires 11 bytes). WGS84 geodetic datum is expected.
[0ddd.dddd.s1MM.MMMM.00mm.mmmm.mmmm.mmmm]
bit: 0…13 Decimal fraction part of minutes.
bit: 14…15 00.
bit: 16…21 Integer part of minutes.
bit: 22 1.
bit: 23 Sign bit. 1 specifies South, 0 specifies North.
bit: 24…30 Degrees.
bit: 31 0.
Example: N 50°25.6760' = 50.427933° = NMEA “5025.6760,N” is 0x32591A68.
Value 0xFF?????? specifies a sensor error. Conversion to the decimal degrees is d + M.m / 60.
• FRC 4-byte: FRC return value equals unmodified return value.
