GT 1500
Speed, Power and Flexibility
Description
Tackle any job with confidence
Not every job is easy, and locating critical features isn’t always straightforward. When accuracy matters, the GT-1500 robotic total station delivers precise data collection and layout, helping you stay on budget and avoid costly mistakes.
With flexible 2-man or 1-man operation, the GT-1500 robotic total station provides for superior data collection and layout of critical items. Its intelligent Brushless Direct Current (BLDC) motor ensures smooth, silent operation with less wear and tear – extending the instrument’s lifespan. Combine with GNSS and create a hybrid solution that allows for the most versatile method of positioning in the industry.
Quick tracking and smart motor control allow the GT-1500 to acquire and track the prism efficiently, even in the toughest conditions. This means you can trust your measurements, record
them and move on to the next job. Don’t stand and wait for the robot to find you, get to work and get the job done.
With Topcon’s auto-pointing technology, setup is faster, making this the ideal tool for construction layout and monitoring projects.
If getting it right the first time matters, the GT-1500 is the tool for the job.
» 200°/sec turning speed for quicker 2-face measurements and hybrid search
» Ultra-silent for confident use
» 10 Hz EDM update rate for faster and more efficient staking
» Compact and lightweight for better handling
» Hybrid ready so you can conquer any job site
Lock onto your prism quickly and easily
On a busy job site, obstacles can break the connection between your total station and prism, leading to frustrating delays. Reacquiring that lock manually takes time – but there’s a better way.
The RC-5A optional remote control provides the fastest and simplest way to relock the connection to the prism when the line of sight has been interrupted. With a single tap in your field software, your robotic total station detects the RC-5A’s fan-shaped laser beam and relocks in seconds. No more wasted time – just seamless operation and maximum efficiency.
• 300 meter, single-tap prism acquisition
• Extends instrument communication to 600 meter using Longlink™
• Ruggedized IP-65 rating
• 40 hour battery life
Ultra flexible
Works in two-person mode (behind the instrument) or oneperson robotic mode. Seamlessly switch between configurations using the same Topcon Field software, ensuring easy file exchange and workflow continuity.
Ultra powerful
Intelligent Brushless Direct Current (BLDC) motor control provides smooth and silent operation with less wear and tear. Ideal for survey or building construction, it helps you measure and stake out more points faster, even in tough conditions.
Ultra comfortable
UltraTrac™ prism tracking combines optical sensing with highspeed BLDC motor control for reliable performance in tough job site conditions. Whether working at a distance or up close, the instrument maintains prism lock making you more productive in any environment.
Ultra productive
Boost productivity with our hybrid solutions, combining GNSS and robotics for seamless data capture – even under tree cover, with lost line of sight, or at hard-to-reach points. Work faster, tackle more, and take your performance to the next level.
With the GT-1500, you get the efficiency of a single-operator robotic system, the power of longrange reflectorless measurements, and the versatility of Hybrid Positioning™, all in your choice of
1”, 2” or 3” GT-1500 models or 2”, 3” or 5” GT-700 models.
