Topcon GPT-3500LN designed to measure long distances

Topcon Positioning Group’s latest reflectorless total station is built to go farther than ever before. “Measuring the long distance is the key new feature,” said Jan Balkema, account manager with Topcon. The GPT-3500LN is a reflectorless total station for the construction and mining market.

342 Topcon Positioning Group’s latest reflectorless total station is built to go farther than ever before.

“Measuring the long distance is the key new feature,” said Jan Balkema, account manager with Topcon.

The GPT-3500LN is a reflectorless total station for the construction and mining market. With a measuring distance of 2000m, the GPT-3500 is designed to measure farther than any non-prism instrument in its class, Topcon said.

“Incorporating the Topcon advanced time-of-flight pulse technology, the EDM is fast and powerful,” said Ray Kerwin, director of global surveying products.  “The Topcon algorithm filters signal noise to provide accurate measurements even on dark and wet surfaces, where other reflectorless technology might fail.”

Along with its onboard data collection software, the GPT-3500LN can connect to an external field controller, enabling field-to-office connectivity with the MAGNET suite of software solutions. The system also can be paired with a prism to allow for a measurement range of up to 3000m.

Additional features include an IP66 rated design, on-board TopField application software, and battery life of up to eight working hours.

    Innovative mobile radar technology that can detect subsurface problems is now being launched by surveying specialist Data Collection Limited. The system uses a specially designed vehicle to carry out surveys at normal traffic speeds. Ground-penetrating radar is used to generate a cross-sectional profile of the subsurface. This information can be used to assess road condition, helping with planning repairs and re-surfacing.

    Early detection of pavement defects and the causes of deterioration is essential for effective maintenance planning, writes Dr Alena Uus* There is a need for optimisation and development of UK highway survey methods that would provide comprehensive information on the surface and subsurface pavement condition and operate at traffic speed, which eliminates the requirement for lane closures. Performance of non-destructive testing (NDT) methods commonly employed in pavement condition surveys can be potent
