What is GeoLogic's deflection-based Orion™?
How does it differ from a conventional pass-counting GPS landfill system?

Measurement vs. Assumption:

GeoLogic's patented deflection-based Orion™ 1 indicates progress by tracking the position of the waste as the operator spreads it on the working face, and measuring how it moves as you drive over it. A deflection-based system is capable of accurately measuring waste undergoing compaction AND indicating areas that refuse to compact. Spongy or springy material, such as tangled re-rod or sludge, may bounce back after each pass. With a deflection-based system, your operator will be able to see this and make a decision whether or not to expend more effort working that spot. Additionally, there is no need to adjust the software settings if your waste stream changes, since the measurement is valid regardless of what is under the compactor wheels.

A conventional pass-counting landfill GPS system, by contrast, assumes compaction rather than actually measuring it. A pass-counting system tracks progress by recording how often the operator passes over the waste, and indicates that the waste has been fully compacted once a pass count goal has been met. Once this goal is reached, pass count systems will indicate to the operator that the job is done, regardless if full compaction was or was not achieved before or after that pass. For example, a load of dry MSW may require five passes to fully compact, whereas a load of broken concrete C&D material may be so rigid, it is fully compacted after only two passes.

The designers of pass count systems recognize this shortcoming, and to compensate, allow the operator to adjust the pass count goal, with the idea that you can modify it for different waste streams with different compaction requirements. As any landfill manager knows, however, the material coming across the scales in most landfills is anything but consistent. Any fixed pass count goal will be hit-or-miss in terms of compaction efficiency, simply because every load of waste is different.

Fuel and Wear Savings:

GeoLogic's deflection-based Orion™ saves fuel and machine wear by measuring compaction accurately, allowing the operator make intelligent decisions about compactive effort. This information effectively reduces unecessary passes, because the operator isn't spending any extra time driving over areas that have already reached the practical point of refusal.

Since pass-counting systems do not measure compaction (they merely assume it), they are incapable of warning an operator that an area is compacted before their pass count goal is reached. If the goal is set to five passes, the operator will dutifly make five passes over the waste, even if the work was done after only three. The cost of this miscalculation in wasted fuel can easily add up load after load, week after week.

Which makes/models of compactors, bulldozers, trucks and UTVs/ATVs can use the GCS:Density System?

The GCS:Density system works with all compactor makes and models, and many bulldozers, trucks and UTVs/ATVs as well. The system is modular and will be custom installed on your equipment by GeoLogic technicians as part of the system installation.
