Reserved
Bit 6:
Set if the user has entered the command
and the receiver is still in the process of
determining its fixed position.
Bit 7:
2D/3D flag: set in 2D mode (height assumed constant and
not computed).
Error
u1
PVT error code. The following values are defined:
0:
No Error
1:
Not enough measurements
2:
Not enough ephemerides available
3:
DOP too large (larger than 15)
4:
Sum of squared residuals too large
5:
No convergence
6:
Not enough measurements after outlier rejection
7:
Position output prohibited due to export laws
8:
Not enough differential corrections available
9:
Base station coordinates unavailable
10:
Ambiguities not fixed and user requested to only output RTK-
fixed positions
