Machine Control can be put into several different categories. A few are:

  • Indicate or Automatic
  • Laser, Sonic, GPS, LPS (robotic) or mmGPS

Each of these categories is independent of each other. For example, you could have an “Indicate GPS System” or an “Automatic Laser System”. The choice of technology utilized by the contractor would take in various needs and budgets. Some of the factors that would be considered to make a decision could be:

  • Vertical accuracy requirements/grading tolerance
  • Budget
  • Type of project. Do you primarily build a flat surface like a pad or runway versus a more complicated surface such as a road, parking lot or pond?
  • Working environment. Do you have an open view to the sky?
  • Type of machine used for grading.
  • Is your organization comfortable with computers and data?

There are many more considerations that must be addressed before determining which machine control technology, if any, is best suited for your job or your company. A GeoShack Machine Control Specialist has the experience, training, and qualifications to advise you in making the best decision for your organization.
