GTS-230W Series

TOPCON proudly announces the debut GTS-230W Series with 

Bluetooth^® wireless technology. The GTS-230W has wide & 

visible display brought revolution to the surveying industry with 

features and durability. Now the new GTS-230W Series has 

up-graded its basic functions for distance and angle 

measurement in addition to maintaining superb durability against 

the environment. The GTS-230 Series is also provided with 

various kinds of application programs makes surveying work 

quick and simple in the field.

BLUETOOTH® WIRELESS TECHNOLOGY

GTS-230W Series provides cable-free, wireless operation. When used with a 

Bluetooth^® wireless technology capable field controller, you can connect wirelessly to 

the GTS-230W Series. No more cables to loose or break !

WIDE & VISIBLE DISPLAY

The GTS-230W series has an advanced graphical display (160 x 64 pixels). With this 

wide visible display, the measurement information is clear and easy to see.

SUPERIOR BASIC FUNCTION FOR MEASURING DISTANCE & ANGLE

The GTS-230W Series is provided with a distance measuring range of 3,000m (9,900ft) 

to a single prism which is superior in its class (GTS-239: 2,000m (6,600ft) / 1 prism), 

while maintaining high accuracy ±(2mm+2ppmxD)m.s.e.(GTS-239:±(3mm+3ppmxD) 

m.s.e.). As for distance measuring time, data updates at a high rate speed of 1.2 

seconds in the fine measurement mode. (0.7 seconds in the coarse mode, and 0.4 

seconds in the tracking mode). This shorter distance measurement time will allow you to 

increase your efficiency and productivity in the field.

INCREASED INTERNAL MEMORY FOR DATA STORAGE

The GTS-230W Series has the internal memory to store up to 8,000 points for data 

collection, or up to 16,000 points for layout work. This substantial memory capacity is 

more than adequate for most applications.

DUAL-AXIS COMPENSATOR

Dual-axis compensation is available for GTS-230W model. This dual-axis tilt sensor 

automatically corrects the vertical and horizontal angle compensation for mis-leveling 

error.

RESECTION

Instrument coordinates can be calculated by measuring known points (Maximum 7 

points) stored in the internal memory. Scale factor can be used in the calculation and 

standard deviation of measurement can be calculated. 

SIDE SHOT

Set the instrument on a known point. After collecting the side shot angle and distance, the 

side shot point coordinate is calculated and stored in the coordinate data file.
