5-
Levelling Active
Basic levelling and heading determination; no
navigation output
Nav: Degraded
Navigation active but with loose error model
Nav: Aligned
Navigation with full error model correction
Nav: Full
All user specified accuracies are met
The normal operating condition for POS MV is navigate mode.
IMU Status - this field may display OK, Warning or Failure.
If the Inertial Measurement Unit (IMU) status field shows anything
except OK, check the Fault Detection window described in
Faults and Messages on page 5-11. Contact Applanix for advice
if necessary.
Nav Status - displays the source and quality of the GNSS sensors
and the resulting mode of the navigation solution.
DR (Dead
Reckoning )
No GNSS input is available; navigation is using
only the IMU data
RTCM DGNSS
Navigator is tightly coupled using the primary
GNSS raw observables plus base GNSS
corrections (RTCM 1 or 9)
CODE DGNSS
Navigator is tightly coupled using the primary
GNSS raw observables plus base GNSS
corrections (RTCM 18 and 19, CMR, CMR+)
FLOAT RTK
Navigator is tightly coupled using the primary
GNSS raw observables plus base GNSS
corrections (RTCM 18 and 19, CMR, CMR+)
FIXED RTK
Same as Float RTK but better accuracy
Pri. C/A
Navigator is loosely coupled using the primary
GNSS position data in C/A mode
Pri. DGNSS
Navigator is loosely coupled using the primary
GNSS position data in DGNSS mode
Pri. P Code
Navigator is loosely coupled using the primary
GNSS position data in P-CODE mode
