The GPT-9000A robotic total station provides precise reflectorless measurement up to 2,000 meters - more than 6,500 feet (1Â¼ miles) - and can easily focus on small objects like power lines. The onboard computer, with a bright, full-color touch-screen display, and faster servo motor technology improve field productivity.
The GTS-900A series reflector-only instruments are available with the same system components.
Additional features on the new series of instruments include:
- X-TRAC technology with instantaneous re-acquisition of target lock;
- Completely cable-free design-all components;
- Large color, touch-screen interface, running off Windows Mobile OS;
- New, ultra-fast robotic servo technology;
- All components fit into a single carrying case;
- Integrated 2.4 GHz interference-free spread spectrum radio;
- Instruments available in 1-, 3-, and 5-second arc-second angle accuracies;
- Field scan imaging ready for the job site;
- Newly designed, lightweight 360-degree prism; and
- New TopSURV field controller software.
Topcon's new RC-3 tracking system, providing positive instrument lock with the simplicity of one-touch operation, is also included. Integrally designed to work with the new 360-degree prism, the RC-3 offers the simplicity of one-touch operation and the industry's fastest quick-lock prism acquisition. Six communication channels enable multiple robotic systems to operate on the same site.
Ray O'Connor, Topcon Positioning president and CEO, said the new GPT-9000A and the GTS-900A series "simply set a new standard for robotic total stations. These instruments are the smartest, fastest, and longest measuring robotic stations available in the market, and the advanced technology can give pinpoint accurate measures from incredible distances.
"Precision reflectorless measurements at up to 1 Â¼ miles? Unheard of . . . until now," O'Connor said.
Peter Wallace, Topcon's director of sales-survey, said the "rugged construction of the new GPT-9000A and the GTS-900A robotic series is waterproof and dustproof, thus enhancing reliability. In addition, putting all components into a single case for ease of transport to the job site saves time and increases productivity."
He said, "Many professionals prefer to use total stations for topos, layout, and grade staking," he said. "Topcon's newest robotic systems offer numerous new features to expedite these routine tasks and save valuable time during every phase of a project."
Wallace said, "While all robotic instruments require line-of-sight between the instrument and rover rod, Topcon has solved the common job site obstruction problems. With the RC-3 quick-lock system, reacquisition of the target is just a single keystroke away," he said.
The RC-3 sends a signal from the rover pole to the instrument. Wallace said, "The instrument detects the signal and automatically turns direct to the prism pole. It's absolutely reliable and takes a fraction of the time spent manually directing an instrument."
