Using Single GNSS for Guidance

If you have selected a single GNSS position source, then the selected design (or depth and slope surface) and any associated 3D data will be visible in the work screen. Guidance is given to the selected design or surface when the center of rotation (COR) is known.

When using single GNSS for guidance, the system will lose COR whenever you move the undercarriage. To regain COR, you need to rotate the machine's cab.

Limited guidance can continue when COR is lost, using the position of the GNSS receiver. The distance to avoidance zones is larger and is derived from the GNSS receiver and not the machine boundary when COR is lost.

NOTE –The cross–section and profile guidance views are not available when COR is lost.

Single GNSS on Cat Next Gen excavators allows reduced swing to regain the machine position and COR. You will be able to regain the COR with a single swing, however for best accuracy you should swing and return to your digging position.

TIP –

  • For best performance with single GNSS on Cat Next Gen excavators, use a MS9x5 or MS9x6 GNSS receiver. A MS9x2 receiver can also be used but with lower performance.

  • For best accuracy with single GNSS, ask your technician to perform a Mast Measure‑up in the Web Interface using the Total Station method.
