Calculate Antenna Offset

Antenna Offset Calibration

Note: Survey rover is required to calibrate Hammer Antenna Height. Using a survey rover, place the survey rover on Top/Center on the installed pile. Remove any Rod Height values in the data collection software and set to 0.0. Set survey rover antenna to read from base of receiver. Record the NEZ (Northing, Easting, Elevation) at top/center of pile using the survey rover.

Note: Hammer Antenna is machined to locate directly above the center of the striker plate. Right & Forward Offset should be 0.0 or close to 0.0 if the hammer and mast are parallel with one another. As hammer bushings, pucks, and shims show wear, the Right/Forward offsets may show a slight offset in the calculated values.

  1. Once you have selected offset options to calculate, press NEXT.
  2. If Calculate Height is the only selected option, the software will prompt you to lower Float the hammer on top of the calibration pile.

  3. Select which offsets should be calibrated. Calibration will only apply to selected offsets
  4. Enter the surveyed Northing, Easting, and Elevation of the pile and press Read GPS and Calculate Offsets.

  5. Then press Next.
  6. Offset will be calculated and populated.

  7. Press OK.

Calibration is Complete.

Check Calibration

Check Calibration XYZ (Easting, Northing, and Elevation)

  1. When checking XYZ, survey the center of the pile that will be used to check calibration.
    Check Offsets
    Check Offsets
  2. Enter surveyed N,E,Z from the Center of the pile.
  3. Press Calculate XY Deltas.
  4. The software will prompt you.
  5. position the hammer centered 4"-6" above the pile.
  6. Level Mast to within ±0.1°.
  7. Hammer should NOT be loaded onto the pile when checking XY. If the weight of the hammer is on the pile, this will cause hammer antenna horizontal offset errors during the calibration check.

The deviation between surveyed point and Hammer position will be calculated in the Right and Forward Delta values.

Check Calibration Z (Elevation)

  1. When checking Z, survey the center of the pile that will be used to check calibration.
    Check Z
    Check Z (Elevation)
  2. Enter surveyed Z from the Center of the pile.
  3. Press Calculate Z Delta.
  4. The software will prompt you to lower Float the hammer on top of the calibration pile. Ensure the hammer is loaded onto the pile.
  5. Level Mast to within ±0.1°.
  6. Press OK.

The deviation between surveyed point and Hammer position will be calculated in the Height Delta value.
