# GNSS survey status

When the controller is connected to a receiver, the status line displays the current GNSS survey mode:

No Survey

The receiver is connected but a survey has not been started.

RTK+IMU

The current survey type is RTK and IMU tilt compensation is enabled.

RTK:Fixed

The current RTK survey is initialized, and the solution type is L1 fixed‑centimeter‑level.

RTK:Float

The current RTK survey is not initialized, and the solution type is L1 float.

RTK:Check

The current RTK survey is verifying the initialization.

RTK:Auton

The radio link is down in the current RTK survey, and the solution is an autonomous position.

RTK:SBAS

The radio link is down in the current RTK survey, and the solution is an SBAS position.

xFill

Radio signals are no longer being received. xFill or xFill‑RTX is enabling RTK to continue.

RTX+IMU

The current survey type is RTX and IMU tilt compensation is enabled.

RTX

The current survey type is RTX.

OmniSTAR HP

The current survey type is OmniSTAR HP (high‑precision).

OmniSTAR VBS

The current survey type is OmniSTAR VBS (differentially corrected).

SBAS

The current survey type is differential, and using signals from an SBAS.

FastStatic

The current survey type is FastStatic.

PPK:Initialized

The current postprocessed kinematic survey is initialized. When postprocessed, it should yield a centimeter‑level solution.

PPK:Not initialized

The current postprocessed kinematic survey is not initialized. When postprocessed, it may not yield a centimeter‑level solution.

Infill:Initialized

The current postprocessed kinematic infill survey is initialized. When postprocessed, it should yield a centimeter‑level solution.

Infill:Not initialized

The current postprocessed kinematic infill survey is not initialized. When postprocessed, it may not yield a centimeter‑level solution.

Infill

The current survey type is differential, and you are doing an infill session.

If the controller is connected to a receiver equipped with HD‑GNSS technology:

in the status line indicates the precision tolerances have been met.
