TS-1 Calibration and Implement Length Verification

In Simulation

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
