Landfill Waste Compaction
The Industry's Most Accurate Measurement Tool
GeoLogic's Orion™ is the premier landfill GPS tool on the market today, mainly because of its superior abilty to measure waste density.

GCS:Density's compaction features include:
  • Real-time progress map based on deflection - not pass counts
  • Information sharing between compactors
  • Marking special loads, special points and features
  • High visibilty for operators
  • Progress monitoring from the office

GPS: The Future of Landfill Compaction
If you are researching a landfill GPS system, you are likely already aware of the buzz in the landfill industry around GPS-assisted compactors. While some facilities are investing in GPS to augment the capabilities of their existing fleet of compaction equipment, many are choosing to invest in this new technology as a compliment to a new compactor purchase. The reason is simple: the best GPS systems take the guesswork out of machine operation by showing landfill managers and operators what is actually going on beneath the wheels of their expensive new compactor.

Track Performance in Real Time
While bigger and more powerful compactors are capable of increasing the density of your waste, only a GeoLogic Orion™ allows you to measure that performance in real time and justify your investment. Whether you are contemplating a new compactor purchase and looking to get the most "bang for your buck", or investing in a productivity tool for your existing fleet, the GeoLogic Orion™ provides the information your operators need to work more efficiently, maximize waste density and improve your bottom line.

The Best Measurement Tool on the Market
The GeoLogic Orion(TM) system, running the GCS:Density© software, is the most effective compaction system available today. When evaluating your options, you will find that all GPS systems for landfills include software that allows both the compactor operator and management to track compactor positions and view compaction information. The difference with GCS:Density is in how effectively it uses that information. Most systems rely on pass-counting to indicate compaction. GCS:Density's more sophisticated software uses advanced, patented1 deflection information to calculate waste density. As an operator using GCS:Density© works, his map on screen changes to indicate measured surface deflection, instead of counting passes and assuming compaction is taking place.

Improve Waste Density with GPS
Although it has many other functions, the GeoLogic Orion™ is best known for it's ability to increase waste density. Compactor operators use the accurate information provided by GCS:Density© to identify waste that isn't fully compacted and focus more efforts on those locations until they reach the practical point of refusal. This point may vary according to your waste stream, but your deflection-based GPS measurement will always be valid. By taking the guesswork out of machine operation, the GeoLogic Orion™ allows the operator to work substantially more efficiently and increase the density of the waste.

In an internal study done by one of our corporate customers, GeoLogic's system was found to increase in-place waste density by 7-14%. The customer verified that the results were not due to changes in incoming material, weather, or operator technique by comparing weeks of GPS-assisted performance against non-GPS operation.

"On average, I would estimate we saw an increase of about 300 to 400 pounds per cubic yard since we began using the GeoLogic GPS System."1

Excellent Operator Viewability for Ease of Use
A common complaint of operators of other landfill GPS systems is that the compaction information on their screens is either unreadable or simply incomprehensible. If the operator can't see or understand the information, merely working with the GPS turned on isn't going to make him more efficient. GCS:Density© uses an straightforward color coding system to indicate both where new material has been placed and where material is undergoing compaction. While other systems choose to display their progress map as a grid of flashing boxes, GCS:Density's map shows the machine's actual wheel tracks so that operators can see their path of travel. When an operator is working a 60 ton compactor in close proximity to other people and vehicles, he shouldn't be squinting at a tiny screen for progress information squeezed in by side views and design information. Operators using GCS:Density© need only a quick glance at the full-screen map on the large, easy to view 12.1" ruggedized touchscreen computer.


Save Fuel, Reduce Machine Wear
GCS:Density© saves fuel and machine wear by providing operators with the information they need to make intelligent decisions about compactive effort. Accurate deflection information helps the operators know when an area has reached the practical point of refusal and they can move on. By reducing the amount of wasted machine time, the GeoLogic Orion™ saves fuel and wear and tear on the machine. GCS:Density's deflection-based system will save more fuel than a pass-counting system, simply because the information produced by a pass-counting system is less accurate, and inaccuracies result in unecessary passes.

"Before GPS, the old way of doing things was to just continuously run over the trash. With the GeoLogic system, we now can see in the compactor cab when the trash is not compacting anymore and it’s doesn’t do any good to keep rolling over it."2

Mark Special Loads, Record Movement History
Many landfills have a legal or safety requirement to record the location of certain hot or special loads, such as buried asbestos or sludge. GCS:Density© includes a function that allows the operator to press a button to mark and label a particular point, line or area for later reference. This information is archived daily in a point report.

In the event an unanticipated hot/special load is deposited on the landfill, management has the option of consulting the software's archives, since all compactors using GCS:Density© record movement as time-stamped points. These points are archived and can be used to pinpoint the exact locations of the compactor during the time frame in question. For example, the archive may be used to find all of the compactor movement recorded between when the unknown hot/special load was brought to the landfill and recorded at the scale house until it is likely that the truck left.
