Overview for the Topcon OS 101 1 Second Reflectorless Total Station

The Topcon OS-101 Total Station with 1-second accuracy and complete MAGNET Field software built-in enables surveyors to perform all calculations onsite without the need for a data collector. This highly-accurate reflectorless total station features a powerful EDM and trigger key. It also has an advanced angle encoder system and exclusive long-range Bluetooth technology for precise distance and angle measurements even in remote locations. With an easy access USB port, alphanumeric keyboard, touchscreen display and advanced security feature, the Topcon OS is an all in one tool for land surveying.

Ultra-Powerful EDM and Angle Encoder

Featuring a high-end EDM beam and laser pointer, the Topcon OS is able to measure up to 1,640 feet in reflectorless mode and up to 16,400 feet to a standard prism with an incredible 2mm+2ppm accuracy. This total station’s ultra-narrow EDM beam precisely measures walls, corners and through fence openings and tree branches in only .9 seconds.  The green or red guide light makes outdoor aiming quick while providing the remote rod-man with direction during stakeout.

The Topcon OS-101 incorporates the exclusive Independent Angle Calibration System (IACS), which allows the instrument to self-adjust its angle measurement system.  It has a motion clamp and precise tangent locks to keep the angle positions accurate even when you are pressing the touchscreen and keyboard. The EDM trigger key is ergonomically placed and allows the surveyor to easily move from the horizontal tangent to get a series of measurements.

Dual-axis compensation ensures accurate leveling even on rough terrain and a built-in laser plummet allows for quick instrument setting with 5 brightness levels.

On-board MAGNET Field Software

Built-in Topcon MAGNET Field software optimizes the dual large color touchscreen and alphanumeric keyboard of the Topcon OS total station to view points and lines with ease.  With the onboard Windows CE 6.0 operating system, this data collection software offers an easy to use graphical interface with large touch icons that indicate what data is needed on each screen. MAGNET Field not only provides a very productive interface, but also features many stakeout, roading, coordinate geometry (COGO) and adjustment calculations that eliminate the need for a data collector.

Long-Range Bluetooth

If you do want to use a data collector or other handheld device, LongLink allows surveyors to operate more than 1,000 feet away from the 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

TSshield is an advanced security feature of the OS total station, which 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

Easily store and transfer files to your PC or data collector with its large 750 MB internal memory, 8GB USB flash memory and RS-232C serial port. Working up to 20-hours on a single charge, the OS-101 along with the Topcon ES Series total station has one of the longest battery-lives in the industry. And with an IP-65 rating, this field instrument is dustproof and protected against water jets from any angle.

For field operations where a data collector is critical, the OS-101 total station can be used with any of Topcon's field controllers, such as the Topcon Tesla, FC-2600, FC-250, FC-236 and FC-25.

This Topcon total station package comes with a lens cap, lens hood, stylus pen, tool kit, USB stick, carry case with straps, wiping cloth, battery, battery charger  and a 2-year manufacturer’s warranty.
