Contents
Unsigned short 2
Sequence tag (unit: 50 ms) modulo 30 minutes. See
NOTE 1 below.
Unsigned char 1
Number of remaining structure to be sent for current
epoch
Unsigned char 1
Satellite index number
GPS: 1-32
SBAS: 33-51
GLONASS: 65-88
Unsigned char 1
Satellite elevation angle (degree)
Unsigned char 1
Satellite azimuth angle (2-degree increments)
Unsigned char 1
Channel ID not duplicated for the current epoch
29
C/A code data
block (29 bytes)
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.
