Usage Of GPS Machine Control Files For Earthmoving

By Mayra Pierce


Global Positioning System or GPS has been included in earthmoving industries for a certain time already. The heavy equipment manufacturers applied this technology on various procedures. These procedures are land grading, causeways, roads, levees, railway beds, canals, and berms.

Due to demands for cost effective production in most industries, a lot of the production has developed advances and innovation in order to meet these demands. GPS machine control files is being utilized in the earthmoving industry in order to spend less for resources. It would also make work easier and faster.

By the end of the 1990s, leading heavy equipment corporations have been applying this innovation and dominated the market sector for this technology while advancing it even further. The system works by simply comparing the position of the current location with the blade of the graders. It indicates the difference while being able to adjust them automatically. The GPS then comes into place for this procedure.

3D and 2D software are now being utilized, developed, and being upgraded even further to help with this sort of procedure. The topography map of the area is imported to these software for it to let the operator have a better visualization for the whole area. Leading companies are actually making their own software and constantly making revisions and upgrades to give higher accuracy in the process.

There are two types of systems that are being used in earthmoving for the heavy equipment industry. They are simply categorized as Indicate Only and Fully Automatic. These two systems can use one or also two of the receivers. Having only one would limit the guidance system in the orientation of the position of the machine. Having two would allow two points of the position which gives also the angle of the machine in relation to the site plan.

Having an accurate topographic map and design would fully utilize the GPS capabilities and give accurate results. These files are most likely from an engineering firm and then can be converted to the display for GPS. A few guidance systems has the capability to define the elevation and angle of the grade, too.

The heavy equipment that can be installed with guidance systems are as follows. Motor Graders, Scrapers, Hydraulic Excavators, and Compactors. Having that installed would make the machines more efficient and productive in terms of accuracy and cost effectiveness. Having this can give less manpower or on site workers.

A machine installed with this system can cost to around one hundred million dollars. When used to the full potential, it can give back to more or less thirty percent of the productivity compared to that from traditional methods. Because of its high accuracy, a lot of projects are requiring the use of GPS in order for them to have lesser expenses.

The limitation is only due to obstructions of the signals and including the surrounding environment as well. Considering the location and environment of the production site should be done in order to have the guidance system to work at its best. Nearby buildings and their roofs can obstruct the signals from the satellite and can make dead zones. Even so, Global Positioning System is still used in advanced Earthmoving due to its advantages and efficiency.
