Set Level String
Match Elevation
Antenna Measurements (using GPS)
Compare GPS measured distance to the physical measured distance to adjust Main/Aux Antenna position
RTK Solution (Single point localization )

Rover with Pocket 3D
Verifying Main Antenna to Boom Length
Position the machine directly North
Mark bucket location and record Northing value
Rotate 180o
Position the machine directly North
Mark bucket location and record Northing value
Verifying Main Antenna to Boom Length
Subtract the two Northing values to get a GPS distance•15.50’
Using a tape or Rover measure the actual distance•15.30’
Subtract the two values and divide by 2•(15.50-15.30 = .20)/2 = .10
If the GPS measured(Northing) value is larger shorten the length in 3D-MCIf the tape measured value is larger lengthen the length in 3D-MC

Verifying Aux Antenna to Boom Length
Rotational Heading
Verifying Aux Antenna to Boom Length
Position the machine directly North
Curl the bucket in and record:•3DMC Easting of a bucket corner (position screen)•Easting with Rover and Pocket 3D
Extend the bucket to its fullest and record:•3DMC Easting of the same corner (position screen)•Easting with Rover and Pocket 3D
Verifying Aux Antenna to Boom Length
Curled bucket Easting:•3DMC 520.35•Rover 520.38
Extended bucket Easting:•3DMC 520.36•Rover 520.51
The difference in curled position•520.38 - 520.35 = .03
The difference in extended position•520.51 – 520.36 = .15
Measured distance from curled to extended•20’
Verifying Aux Antenna to Boom Length
Determine the Aux antenna correction amount using this formula:
A(Distance Between Antennas) C(Ext Easting – D (Curl Easting) X B (Curl To Ext Distance)
=
7.5 .15 - .03 X 20
= X=.045
Rover Easting's larger (decrease)3DMC Easting’s larger (Increase)
Curled bucket Easting:•3DMC 520.35•Rover 520.38
Extended bucket Easting:•3DMC 520.36•Rover 520.51
Excel Verifying Aux Antenna to Boom Length
Verifying Main Antenna Offset
Position the machine directly North
Curl the bucket in and record:•3DMC Easting of a bucket corner (position screen)•Easting with Rover and Pocket 3D
Extend the bucket to its fullest and record:•3DMC Easting of the same bucket corner (position screen)•Easting with Rover and Pocket 3D
Verifying Main Antenna Offset
Curled bucket Easting:•3DMC 520.35•Rover 520.38
Extended bucket Easting:•3DMC 520.48•Rover 520.51
The difference in curled position•520.38 - 520.35 = .03
The difference in extended position•520.51 – 520.48 = .03
If Rover Easting's are larger (increase)
If 3DMC Easting’s are larger (decrease)
Excel Verifying Main Antenna Offset
Verifying Main Antenna Height
•If 3DMC elevations are higher than the rover increase the antenna height•If 3DMC elevations are lower than the rover decrease the antenna height.
Record several 3DMC bucket elevations and corresponding survey rover elevations
Subtract the elevations and find the average

Testing Machine Sensors for Accuracy
Elevation/Position Errors
Wedge errors or Inconsistent elevation errorsPerform Elevation Accuracy Verification to check machine and sensor calibration
Overall bias between machine and roverPerform Main Antenna Height Verification
Northing Errors:Perform Main Antenna to Boom Length Verification
Rotational Errors: (curled to extended)Perform Aux Antenna to Boom Length Verification
Easting Errors:Perform Main Antenna Offset Verification
