Abstract

A machine control and guidance system for an earthmoving machine, includes one or more sensors and a portable digital media device mounted on the earthmoving machine. The portable digital media device may comprise an iPhone, an iTouch, or other similar device. Each of the sensors senses the position or orientation of a portion of the earthmoving machine and provides a wireless output signal indicating the position or orientation. The portable digital media device is in wireless communication with each of the sensors. The device has an associated display and a memory in which is stored an application program which permits the device to determine the position of one or more portions of the earthmoving machine and to display the position of one or more portions of the earthmoving machine on the display.
