TOPCON GT-503 Total Station

The GT series of robotic total stations are a trimmed down, high-performance solution that's ready to impress today, yet still grow with you into tomorrow. You get the efficiency of a single-operator robotic system, the power of long range reflectorless measurements, and the ability to perform as a hybrid positioning solution. All in a compact system that’s a third smaller and twice as fast.

UltraSonic technology is the driving force for the GT Series. You can see and hear the difference immediately. The UltraSonic motors are the fastest available in the market - at 180 degrees per second it's the smoothest and most accurate prism-tracking available.

  • Ultrasonic Direct Drive motors;
  • 30% smaller and lighter with more functionality;
  • TSshield™ global service;
  • Advanced UltraTrac technology;
  • 5 Year Guarantee;
  • Available in two models—GT-500 and GT-1000.
