GPS Reference Manual Stake Points 6WDNHRXW 6WDNH 3RLQWV The Stake Points screen in used to locate and stake out points in the field from coordinates in the job file. The first two screens of this routine 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.
Stakeout Menu Rover is greater than 3 m (10 ft) from the design point. Rover is between 0.3 and 3 m (1 and 10 ft), from the design point. Rover is within 0.3 m (1 ft) of the design point. Go EAST / WEST: displays the distance the rover must move in an east or west direction to reach the design point. CUT / FILL: displays the required cut or fill between the current elevation and the design point. 5 Hz Mode: switches the receiver from One Hz to Five Hz mode.
GPS Reference Manual 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 'RQH . The occupation is not stored in the Survey Pro .RAW file if you toggle back to ROVING.
Stakeout Menu Stake to Line – Screen Two The second screen is where measurements take place and the staking directions are displayed. The graphic and display direct you to points on line via the shortest route, a perpendicular offset from the rover to the line. The graphic display will change depending on how close you are to the specified line. The chart below illustrates each screen type. Rover is greater than 3 m (10 ft) from the line. Rover is between 0.3 and 3 m (1 and 10 ft) from the line.
GPS Reference Manual 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. 2&&83<,1* / 529,1* : switches from ROVING to OCCUPYING mode.
Stakeout Menu 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 Although the graphic portion of the screen is continuously updated, the numeric values are not updated until the 6KRW button is tapped. The correct procedure for slope staking in GPS mode is to use the graphic portion of the screen to locate the catch point as closely as possible and press 6KRW . Once the position is satisfactory, you can determine if the rover needs to be moved again.
Stakeout Menu Note: The Vertical Map will show an X at the location of each previous shot. This can be useful in determining if the current terrain will never intersect the slope (no catch point). • • + 0DS : displays an overhead view of the job. 1 ( = : displays the coordinates computed from the last shot. 2FFXS\« : switches the receiver dynamics to static (depending on settings) and opens the Occupy Data Points screen (Page R-36) where data can be collected for the current point.
GPS Reference Manual VD to HP: is the vertical distance from the rod to the hinge point. HD to CL: is the horizontal distance from the rod to the centerline. VD to CL: is the vertical distance from the rod to the centerline.
Stakeout Menu 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.
GPS Reference Manual 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.
Stakeout Menu 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 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.
