GTS-820 Series

Speed, precision, versatility, reliability.  The new GTS-820 series puts it all in a package to deliver the highest productivity day after day, in all field conditions.  Compare it to any other robot.  Sight the prism, activate the unique Topcon "wide beam" tracking system and the instrument locks on and follows the reflector wherever it goes.  The fast servomotors will track the prism at a speed of more than 12 degrees per second.  A full 30% faster than before.

The GTS-820 now features advanced CCD tracking technology which incorporates Movements Anticipation technology.  This keeps the beam stuck to the prism for unprecedented tracking accuracy.  It is available in 3 model; the GTS-821a (1-second angle accuracy), the GTS-823a (3-second angle accuracy), and the GTS-825a (5-second angle accuracy).
