Topcon GPT-8003A 3" Auto Tracking Total Station

Topcon GPT-8003A Full Robotic Total Station
The GPT-8003A series are non-prism total stations with built in auto tracking offering the option for one person surveying from behind the instrument or at the prism.

Fast auto tracking
GPT-8003A has a very fast tracking speed of 12º per second ensuring that loss of lock only normally occurs due to obstructions and not due to the movement of the prism. 12º/sec is approximately equivalent to 75 km/h at 100m. This results in reliable prism lock and better performance in machine control and other applications where fast or erratic movements can be expected. The GPT-8000A series uses a new CCD tracking system, which identifies the prism and ensures only the prism can be followed by the instrument. This system increases the speed and reliability of tracking.

Super Fast Find
The super “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 Topcon’s 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 area around the prism where auto lock is activated has been increased from 1º to 5º in the GPT-8003A. 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

Reflectorless measurement
To offer complete flexibility to your surveying procedures the GPT-8003A can measure in non-prism mode over a distance of 120 meters.  This gives the added benefit to the surveyor working on his own, of being able to work behind the instrument to pick up those inaccessible of difficult to reach points.
