Modern land surveying equipment requires a clear line of sight, either upward between GPS aka Global Positioning Systems and satellites orbiting the Earth or along the ground between Microwave Radar Systems aka Total Robotic Stations and Prisms. The need for a clear line of sight while using existing land surveying equipment forces surveyors to destroy plants, shrubs, and trees using bulldozers, chainsaws, and machetes in order to mark property lines or collect data points in the field for land mapping. This not only damages homeowner landscaping, but also decimates wooded areas, forests, and jungles. In addition to causing environmental damage, obtaining a clear line of sight requires additional labor, increasing time spent in the field and overall project costs. With forty years of experience, Thomas G. Pattison, State of Hawaii Licensed Professional Land Surveyor No. 10743, envisioned a new cutting-edge way to mark property lines and collect data points for land mapping while surveying in the thick, lush rain forests of Hawaii and RTR aka Real Time Ranging Technology was born.

Radio frequencies at or below the UHF band level allow electromagnetic waves to penetrate vegetation. I formed a company, RTR Technologies, LLC, along with radio frequency engineers David Farrell and Chirs Pifer. Together we designed a new cutting-edge technology to take advantage of this fact, engineering and successfully testing a RTR or Real Time Ranging Technology proof-of-concept prototype. We patented our new RTR or Real Time Ranging Technology and also secured pre-approval from the FCC for a dedicated radio wave frequency for operating RTR systems. Our goal is to take land mapping to the next level with our smarter greener technology which protects the environment while land mapping when compared to existing technologies like microwave radar and GPS systems. ~ Thomas G.

Our new RTR or Real Time Ranging Technology [approved U.S. Patent No. 10101435 and No. 11035947] works via radio waves to penetrate foliage minimizing job costs and environmental damage. Using the basic LinePro Ground System, the range detector pole is walked between transponders set-up on the property corners. Our radio wave based technology penetrates foliage, emitting a signal when the range detector pole in on the property or boundary line. RTR Technology finds data points along property lines in order to mark the property boundary as well as collecting data points for land mapping without destroying plants, shrubs, and trees. Real Time Ranging Technology also works in open areas, reducing the overall time spent in the field on every land surveying project. RTR Technology may also be mounted on a drone, our SkyRanger Aerial System, or on terrain bots, our GoRover Autonomous System, making Real Time Ranging Technology perfect for other professionals like civil engineers, environmental conservationists, architects, building contractors, landscape architects, fence builders, archeologists, and the military in addition to land surveyors.
