Rover is between 0.3 and 3 m (1 and 10 ft) from the line.
GPS Reference Manual Go EAST / WEST: displays the distance the rover must move in an east or west direction to reach the closest point on the line. 5 Hz Mode: switches the receiver from one Hz to five Hz mode. When this box is checked, the receiver will compute positions five times a second so the display will update in near real time while you are roving to the point. Note: When you switch from ROVING to OCCUPYING, the receiver will be put back in one Hz mode for maximum precision while staking the point.
Stakeout Menu 5HVXOWV / 1 ( = : toggles the display between Results and Current Location. 6WRUH : prompts you for a point name and description and stores a point for the current location. Note: When Store GPS Raw Data on the Job | Settings | Measure Mode card (Page R-8) is set to + BL,CV and/or + Rx. Raw tapping 6WRUH without first switching from ROVING to OCCUPYING will store the point in Survey Pro only; no base line measurement or receiver session will take place.
GPS Reference Manual Slope Staking – Screen Four The graphic portion of the Horizontal Map and Vertical Map is updated continuously. This allows the user at the rover position to watch the movement of the rover in relation to the slope and easily position the rod over the catch point. Note: You can tap in the graphic portion of the screen to open the graphic in a larger window.
Stakeout Menu • )RUFH ),// 6ORSH : forces all computations to be based on a fill slope. The second button selects which information is displayed in the lower corner of the screen from the following options: • 9 0DS : displays a cross-sectional view at the current station. Note: When you tap a map view, an expanded view of the same map will fill the screen. Note: The Vertical Map will show an X at the location of each previous shot.
GPS Reference Manual Toward CL / Away CL: is the computed horizontal distance that the rod must move either toward the centerline or away from it, respectively, before it is positioned at the catch point. Note: The computed horizontal distance is based on the observed terrain computed from the last two shots. If only one shot has been taken, it is assumed that the terrain is level when computing this value.
Stakeout Menu Curve and Offset 6WDNHRXW &XUYH DQG 2IIVHW The instructions for the Curve and Offset routine for GPS are similar to the conventional method, except that the %DFNVLJKW button is replaced with a 6HWXS +5 button to configure rover antenna and the backsight information is replaced with rover antenna height information. See the conventional Reference Manual for details.
GPS Reference Manual Show Station and Offset 6WDNHRXW 6KRZ 6WDWLRQ The Show Station and Offset routine allows you to position the rover anywhere near a polyline, a range of points that define a line, or an alignment to see where the rod is located in relation to the selected line.
Stakeout Menu Note: When Store GPS Raw Data on the Job | Settings | Measure Mode card (Page R-8) is set to + Rx. Raw (and/or +OBN for Ashtech) switching from ROVING to OCCUPYING will start a session in the receiver, so you will be prompted for a point name and description. The receiver session will be completed and the measurement stored when you tap 6WRUH . The occupation is not stored in the Survey Pro .RAW file if you toggle back to ROVING.
GPS Reference Manual Stake DTM 6WDNHRXW 6WDNH '70 The Stake DTM routine allows you to stake an area and get cut / fill and volume information based on a reference DTM or specified elevation datum. The first screen of this routine is similar to the conventional method, except that the %DFNVLJKW button is replaced with a 6HWXS +5 button to configure rover antenna and the backsight information is replaced with rover antenna height information. See the conventional reference manual for details.
Stakeout Menu Note: When Store GPS Raw Data on the Job/ Settings/ Measure Mode card (Page R-8) is set to + Rx. Raw (and / or +OBN for Ashtech) switching from ROVING to OCCUPYING will start a session in the receiver, so you will be prompted for a point name and description. The receiver session will be completed and the measurement stored when you tap 6WRUH . The occupation is not stored in the Survey Pro .RAW file if you toggle back to ROVING.
GPS Reference Manual C.L.: shows the current station and offset information for the rover location relative to the selected centerline. The type of line segment in the polyline at the current station is also displayed. (This card is only available if the With C.L. checkbox was checked in the previous screen.) Note: Tapping anywhere within the map view will open a larger map view, which provides zoom controls.
