Millimeter GPS™ With Millimeter GPS™, you can take your GPS rover and transform it into a super-precise measuring device that rivals a robotic total station. Plus, Millimeter GPS allows you to enable your highly productive 3D-GPS+ stakeless grading systems to speed through your highest precision work. All at a fraction of the cost of a robotic total station system, and without the single-user limitation. That's the power of Millimeter GPS™! Strange Bros. Grading, based in Taylor, SC, performs a wide variety of site work tasks for commercial, residential and industrial projects. One of their most recent projects involved site prep for a new Walgreen’s Pharmacy in Simpsonville. Their scope of work on the 2 acre site included 15,000 cubic yards of imported fill, storm drainage, utilities, curbs, and paving. The real challenge to the project was layout work for redirecting an existing drainage course to allow construction of the building pad. A very limited skyline and working deep in a 50 foot gully were major obstacles to staking with any other make of GPS survey instruments – except Topcon’s HiPer Lite +. Doug Haddock, P.L.S., survey manager for the company, chose the HiPer Lite+ because of its dual-constellation tracking. Access to both GPS and GLONASS satellites lets him work on sites with obstructed sky views where GPS-only systems would fail. This project convinced him that Topcon offers superior products and technology. He also discovered a significant increase in efficiency when performing routine staking and data collection tasks. Doug compared his current productivity with Topcon to his experiences with other systems: “100% increase - achieved through more functionality and more locations through advanced satellite tracking.” For problematic sites like this one, Topcon HiPer Lite+ isn’t just another GPS system—it’s The Perfect Solution!
