4 – 7
Pseudorange iono correction:
0 – unknown or default Klobuchar model;
1 – Klobuchar Broadcast;

3 – Multi-frequency Computed;
4 – DGPS (pseudorange differential correction);
5 – NovAtel Blended Iono Value.
Table C.5 GNSS_info2 – information about GNSS data
Bit
Value and Description
0 – 1
Solution status:
0 – GNSS solution is computed;
1 – insufficient observations;
2 – not yet converged from cold start;
3 – other reason of absent solution.
2 – 3
GPS reference time status:
0 – time validity is unknown;
1 – time is coarse set and is being steered;
2 – position is lost and the range bias cannot be calculated;
3 – time is fine set and is being steered.
4
1 – GPS GNSS signal is used
5
1 – GLONASS GNSS signal is used
6
1 – Galileo GNSS signal is used
7
1 – BeidDou GNSS signal is used
Table C.6 New_GPS indicator of new update of GNSS data
Bit
Value and Description
0
1 – GNSS position data update
1
1 – GNSS velocity data update
2
1 – GNSS heading data update
3
1 – valid 1PPS signal received
4
1 – GNSS BESTXYZ log update
5
1 – GNSS PSRDOP log update
Note: INS onboard GNSS receiver generates 1PPS signal all the
time, but the New_GPS indicator sets bit #3 to 1 only if GPS
reference time status is fine (see also Table C.5).
