The GPT-8200A series is designed for specialist applications such as building surveys, quarry surveys and volumetric monitoring but is equally suitable as the ideal multipurpose total station for standard survey jobs for one-person or two-person surveying. One person surveying can be done from behind the instrument in Non-Prism mode or using the Topcon RC-2 II for remote control from the prism.

Topcon Auto Tracking total stations offer the very best performance using laser communication and pulse-laser distance measurement technology. The GPT-8200A series are Auto Tracking Robotic Total Stations that form the central part of the Topcon Solo Surveying System which is completed by adding the unique Optical Infrared communications device Topcon RC-2II and Topcon FC-100 Field controller. The GPT-8200A series have a long range Non-Prism distance measurement with the capability to measure a distance of 1,200m without a prism.

Unique Remote Control
Topcons system for solo surveying is based on the principle of using an optical data link for communication between the prism position and the instrument. Using the GPT-8200A / GTS-820A with the remote control device, RC-2 II, the surveyor can talk to the total station, giving instructions to measure and tell the instrument where the prism is after a loss of lock. What is more, the total station can talk back to the surveyor, sending all the measured data for storage in the handheld controller unit.

Fast Find
The "Fast Find" function is a major advantage of the system ensuring quick re-location of the prism after loss of lock, with the simple press of a button. Using Topcons unique laser optical communication technique the RC-2 II directs the total station to the prism position. Weighing only 300 grams and the size of a small pocket calculator, the RC-2 II, when activated, sends a signal, which is detected by the total station. The total station then quickly turns to the correct direction and vertical angle setting to locate the prism.

Fast Auto Lock
The Auto Lock function is activated within an area of 5 degrees around the prism. This allows the prism to be identified within a wider field of view so that automatic sighting takes over from manual sighting sooner and only rough pointing to the target is necessary.
