Summary: | The invention relates to an apparatus and method for augmenting the 3 dimensional position information obtained from the NAVSTAR satellite-based global positioning system ("GPS") system. Such systems can be impacted by physical obstacles that prevent the receipt of the satellite signals or as a result of sun spot activity that introduces noise into the signals thus causing them to become intermittently unavailable and/or making them less accurate in the course ofnormal operation. Therefore, an improved positioning solution that can operate under such poor GPS operational conditions is needed. The apparatus and method of the invention augments GPS with dead reckoning techniques when GPS signals are unavailable or inaccurate. The apparatus and method of the invention demonstrates highest value when applied to blasthole drill positioning applications in open-pit mines. |
