Unsigned char 1
Warning flag
Bit1, Bit2:
0,0: Code and/or carrier phase measured but measure-
ment was not used to compute position.
1,0: Code and/or carrier phase measured, navigation
message was obtained and measurement was used to
compute position but position wasn’t finally computed.
0,1: Code and/or carrier phase measured, navigation
message was obtained, measurement was used to
compute position and position was computed success-
fully.
Bit3: Carrier phase questionable
Bit4: Code phase (range) questionable
Bit5: Range not precise (code phase loop not settled)
Bit6: Z tracking mode
Bit7: Possible cycle slip
Bit8: Loss of lock since last epoch
Unsigned char 1
Indicates quality of the position measurement (good/
bad)
0: Measurement not available and no additional data will
be sent.
23: Code and/or carrier phase measured, navigation
message was obtained and measurement was used to
compute position but position wasn’t finally computed.
24: Code and/or carrier phase measured, navigation
message was obtained, measurement was used to
compute position and position was computed success-
fully.
Other state: measurement was not used to compute
position.
Unsigned char 1
Polarity of the phase tracking
0: Polarity unknown
5: Polarity known
Unsigned char 1 Signal-to-noise ratio for satellite observation (db.Hz)
Unsigned char 1 Always 0. Not used.
Double 8 Full carrier phase measurements in cycles
Double 8
Raw range to SV (in seconds),
i.e. receive time - raw range = transit time
See NOTE 1 below.
Long 4 Doppler (10-4 Hz)
Long 4
Smoothing
Bits 0-22: magnitude of smooth correction in centime-
ters
Bit 23: sign of smooth correction
Bits 24-31: smooth count, unsigned, as follows:
0=unsmoothed
1=least smoothed
255=most smoothed
