4 SBF Reference
Misc
u1 Bit field containing miscellaneous flags:
Bit 0:
In DGNSS or RTK mode, set if the baseline points to the base
station ARP. Unset if it points to the antenna phase center, or if
unknown.
Bit 1: Set if the phase center offset is compensated for at the rover,
unset if not or unknown.
Bit 2: Proprietary.
Bit 3: Proprietary.
Bits 4-5: Proprietary.
Bits 6-7: Flag indicating whether the marker position reported in this
block is also the ARP position (i.e. whether the ARP-to-marker
offset provided with the
setAntennaOffset
command is zero
or not)
0: Unknown
1: The ARP-to-marker offset is zero
2: The ARP-to-marker offset is not zero
Reserved
u1 Reserved for future use.
AlertFlag
u1
0
Bit field indicating integrity related information:
Bits 0-1: RAIM integrity flag:
0: RAIM not active (integrity not monitored)
1: RAIM integrity test successful
2: RAIM integrity test failed
3: Reserved
Bit 2: set if integrity has failed as per Galileo HPCA (HMI Probability
Computation Algorithm)
Bit 3: set if Galileo ionospheric storm flag is active
Bit 4: Reserved
Bits 5-7: Reserved
Datum
u1
255
This field defines in which datum the coordinates are expressed:
0: WGS84/ITRS
19: Datum equal to that used by the DGNSS/RTK base station
30: ETRS89 (ETRF2000 realization)
31: NAD83(2011), North American Datum (2011)
32: NAD83(PA11), North American Datum, Pacific plate (2011)
33: NAD83(MA11), North American Datum, Marianas plate (2011)
34: GDA94(2010), Geocentric Datum of Australia (2010)
35: GDA2020, Geocentric Datum of Australia 2020
36: JGD2011, Japanese Geodetic Datum 2011
250: First user-defined datum
251: Second user-defined datum
NrSV
u1
255
Total number of satellites used in the PVT computation.
WACorrInfo
u1
0
Bit field providing information about which wide area corrections have
been applied:
Bit 0:
set if orbit and satellite clock correction information is used
Bit 1: set if range correction information is used
Bit 2: set if ionospheric information is used
Bit 3: set if orbit accuracy information is used (UERE/SISA)
Bit 4: set if DO229 Precision Approach mode is active
Bits 5-7: Reserved
ReferenceId
u2
65535
This field indicates the reference ID of the differential information used.
In case of DGPS or RTK operation, this field is to be interpreted as the
base station identifier. In SBAS operation, this field is to be interpreted as
the PRN of the geostationary satellite used (from 120 to 158). If multiple
base stations or multiple geostationary satellites are used the value is
set to 65534.
MeanCorrAge
u2
0.01
s
65535
In case of DGPS or RTK, this field is the mean age of the differential cor-
rections.
In case of SBAS operation, this field is the mean age of the ’fast correc-
tions’ provided by the SBAS satellites.
In case of PPP, this is the age of the last received clock or orbit correction
message.
