To navigate to a point during stakeout
When navigating to a point during stakeout, the information shown depends on whether you are performing a Conventional or GNSS survey, and the options you have configured in the Stakeout options screen. To configure these options, see To configure the stakeout navigation display.
Conventional survey
To navigate using direction and distance
-
Hold the display screen in front of you as you walk forwards in the direction that the arrow is pointing. The arrow points in the direction of the point that you intend to measure (the "target").
The navigation deltas appear at the bottom of the screen, and indicate the distance to and direction of the target. To change the displayed deltas, tap Options.
- When you get to within 3 meters (10 feet) of the point, the arrow disappears, and the in/out and left/right directions appear, with the instrument as a reference point. To navigate in this mode, see To navigate using in/out and left/right.
When navigating to the position, a grid appears as you near the target. The grid changes scale as you move closer to the target.
To navigate using in/out and left/right
- The first display shows which way the instrument should be turned, the angle that the instrument should display and the distance from the last point staked to the point currently being staked.
- Turn the instrument (two outline arrows will appear when it is on line), and direct the rod person on line.
- If the instrument is not in TRK mode, tap Measure to take a distance measurement.
- The display shows how far the person holding the rod should move towards or away from the instrument.
- Direct the person holding the rod, and take another distance measurement.
- Repeat steps 2–5 until the point has been located (when four outline arrows are displayed), then mark the point.
- If a measurement to the target is within the angular and distance tolerances, tap Store at any time to accept the current measurement.
If you are using a servo instrument, and the Servo auto turn field in the survey style is set to HA & VA, or HA only the instrument automatically turns to the point. If you are working robotically, or when the Servo auto turn field in the survey style is set to Off, the instrument does not turn automatically.
If the instrument is in TRK mode and you require a higher precision distance measurement, tap Measure to take an STD measurement and then tap Store. To discard the STD measurement and return the instrument to TRK mode, tap Esc.
If you are operating a robotic instrument remotely from the target:
- the instrument automatically tracks the prism as it moves
- the instrument continuously updates the graphical display
- the graphical display is reversed and the arrows are shown from the target (prism) to the instrument
GNSS survey
-
Hold the display screen in front of you as you walk forwards in the direction that the large navigation arrow is pointing. The arrow points in the direction of the point that you intend to measure (the "target").
If the Display orientation is set to Direction of travel, the large navigation arrow assumes that you are moving forward at all times.
To change the reference point used by the small orientation arrow, tap the North/Sun softkey.
The navigation deltas appear at the bottom of the screen, and indicate the distance to and direction of the target. To change the displayed deltas, tap Options.
- When you get to within 10 feet (3 meters) of the point, the arrow disappears and a bull's‑eye target appears.
Keep facing in the same direction and only move forwards, backwards, left or right. Do not change your orientation.
When staking a point, line, arc, or alignment a grid appears as you near the target. The grid changes scale as you move closer to the target.
- Continue moving forwards until the cross, representing your current position, covers the bull's‑eye target, representing the point.
- Mark the point.
