Overview for the Topcon OS 103 3 Second Reflectorless Total Station

The Topcon OS-103 Total Station with 3-second accuracy provides on-board MAGNET Field software that enables surveyors to calculate measurements onsite without a data collector. With exclusive Bluetooth communication, this highly-accurate reflectorless total station is able to measure long-range distances in hard to reach places. Its easy access ports, alphanumeric keyboard, touchscreen display and EDM trigger key make the Topcon OS easy to use even for inexperienced users.

Powerful Distance Measurement

With its high-end EDM beam and laser pointer, this Topcon total station is able to measure up to 1,640 feet in reflectorless mode and up to 16,400 feet to a standard prism with an impressive 2mm+2ppm accuracy. Its ultra-narrow laser beam precisely measures walls, corners and through fence openings and tree branches in only .9 seconds. The coaxial green or red guide light is ideal for outdoor aiming and direction during stakeout.

The ergonomically placed EDM trigger key allows the surveyor to take a series of measurements with a press of a button. For accurate leveling even on rough terrain, the OS total station has dual-axis compensation and a built-in laser plummet. It is also equipped with motion clamp and precise tangent locks to keep the angle positions accurate even when you are pressing the touchscreen and keyboard.

MAGNET Field Software and Windows OS

Work directly on the bright, color touchscreen or with the alphanumeric keyboard of the Topcon OS total station with built-in MAGNET Field software. This data collection software optimizes the dual large display so the user can see more functions and intuitively react with the screen. With the onboard Windows CE 6.0 operating system, MAGNET very productive graphical interface and features many stakeout, roading, coordinate geometry (COGO) and adjustment calculations that eliminate the need for a data collector.

Topcon LongLink Technology

If you want to use a data collector or other handheld device, LongLink allows surveyors to operate more than 1,000 feet away from your OS total station! Featuring Class 1 Bluetooth wireless technology, this Topcon exclusive technology offers flexibility for stakeout and other field applications that require the use of a field controller at the prism pole. Simply aim this optical instrument and the remote rod position triggers the measurement from the data controller, eliminating the frustration of hand signals and errors on layout. 

Topcon TSshield Security System

The OS total station features the exclusive TSshield security system that allows the owner to disable the device by sending a coded signal and track its location if it is misplaced or stolen. The same module also offers daily connectivity to cloud-based Topcon servers and automatically sends on-screen alerts for available software updates.

Connectivity and Long Battery Life

With Topcon OS total station’s large 750 MB internal memory, 8GB USB flash memory and RS-232C serial port, you can easily store and transfer files to your PC or data collector. Along with the Topcon ES Series total station, the OS-103 has one of the longest battery-lives in the industry and works up to 20-hours on a single charge.
