Usage Of GPS Machine Control Files For Earthmoving

By Mayra Pierce


GPS or Global Positioning System has now been included in the earthmoving industries. Heavy equipment manufacturers are now applying this technology in their procedures. These are for land grading, roads, causeways, railway beds, levees, dams, berms, and canals.

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.

A lot of heavy equipment corporations have been dominating this market sector and has been advancing this technology for quite a while already since the late 1990s. The system for machine control simply compared the position of the blade with the current location of the equipment. It can indicate the difference or can make adjustments automatically. This is where the role of the GPS takes place.

Various 2D and 3D software are being developed for this procedure. The model for this will then be visualized into either 2D or 3D to allow the operator to study the area further. A lot of companies have been developing their own software and upgrading them for further development and added accuracy.

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.

In order to get higher accuracy for the topography of the area, it should be as detailed as possible. These files can be taken from the hired engineering firm and would then be utilized by the GPS display. Guidance systems can also define and make changes with the angle and elevations of the grades in the area.

Examples of heavy equipment that can be installed with a guidance system are Motor Graders, Hydraulic Excavators, Scrapers, and Compactors. It would help greatly for these machines in accuracy, efficiency, time, and cost effectivity. It also provides less on site manual management by field workers.

The cost for one machine would start about a hundred million dollars. And when this is used at its full potential, it can give about thirty percent above the efficiency and productivity rate compared to traditional methods. Because of high accuracy, there is not much cost on materials and resources. This is the reason why a lot of construction projects are using the aid of GPS as a requirement for them to cut expenses.

Although it has limitations to its effectivity due to the environment since it utilizes signals to work. So this should be taken into consideration in the project site where it is located and what are some obstructions that are nearby. Roofs of buildings or any structure close to the site may create a dead zone for the satellite. Although overall Global Position System used in Earthmoving has been the most efficient and productive method and can be also developed even further.
