24 + 32*N R8 - cpMes cycles Carrier phase measurement [cycles]. The carrier
phase initial ambiguity is initialized using an
approximate value to make the magnitude of
the phase close to the pseudorange
measurement. Clock resets are applied to both
phase and code measurements in accordance
with the RINEX specification.
32 + 32*N R4 - doMes Hz Doppler measurement (positive sign for
approaching satellites) [Hz]
36 + 32*N U1 - gnssId - GNSS identifier (see Satellite Numbering for a
list of identifiers)
37 + 32*N U1 - svId - Satellite identifier (see Satellite Numbering)
38 + 32*N U1 - sigId - New style signal identifier (see Signal Identifiers).
39 + 32*N U1 - freqId - Only used for GLONASS: This is the frequency
slot + 7 (range from 0 to 13)
40 + 32*N U2 - locktime ms Carrier phase locktime counter (maximum
64500ms)
42 + 32*N U1 - cno dBHz Carrier-to-noise density ratio (signal strength)
[dB-Hz]
