Overview for the Sokkia SX 105T 5 Second Robotic Total Station

The Sokkia SX-105T 5-Second Robotic Total Station revolutionizes the surveying industry with its top of the line laser, image, Bluetooth and EDM technologies, combined with advanced tracking algorithms and communication capabilities.

Used in conjunction with Sokkia's On-Demand Remote Control System (sold seperately) long-range measurements up to 3,280 feet, can be taken accurately and reliably from remote locations. The SX robotic total station also takes the shortest reflectorless distance measurements in the industry, as little as 1 foot!

Using Bluetooth wireless technology, the RC-PR5 remote controller enables communication up to nearly 2,000 feet between the data collector of your choice and the SX robotic total station. This advanced remote control unit mounts on a prism pole in conjunction with a unique 360-degree robotic prism. Not only can surveying be completed by one person, but measurements can be calculated two to three times faster than with a standard total station.

Bluetooth Auto Pointer and Auto Tracking

An upgraded model to the former Sokkia SRX, the Sokkia SX-105 robotic total station features auto-point technology that automatically senses the robotic prism to perform sighting. Even in poor lighting conditions, intense reflections and wooded areas, the Sokkia SX remains accurate.

Another unique feature of the SX 5-second total station is the auto-tracking function. Using a built-in directional sensor and Bluetooth technology, the robotic total station rotates and follows the direction of the prism. With this advanced function, you won’t need to worry about keeping the line of sight clear between you and the total station while safely maneuvering around obstacles, trees, traffic and buildings out on the field.

RC-PR5 Remote Control

The RC-PR5 remote unit emits a laser fan beam that is picked up by the detector unit in the handle of the Sokkia SX. Instantly, the total station turns like a compass in the direction of the prism, keeping track of the prism at all times. In addition, the remote unit's directional sensor allows you to re-establish contact with the instrument. Simply press the trigger key, and the total station automatically rotates in the shortest direction towards the prism.

Stable Measurement Options

The auto-tracking function also allows you to select sighting accuracy and speed by choosing the imaging mode that best suits the job. While the digital imaging mode is fine for many situations, the optical imaging mode is ideal for achieving accurate measurements when dealing with an unstable or shaky prism pole.

Sokkia's robotic total station is equipped with an advanced angle measurement system. This system features an original absolute encoder. Combined with the SX total station's dual-axis compensator, accurate and stable measurements are guaranteed even on uneven ground. 

Long-range EDM 

The Sokkia SX-105 used RED-tech EX technology for pinpoint precision in distance measuring. RED-tech allows surveyors to perform a variety of electronic distance measuring tasks (EDM) more quickly and accurately than ever before. It measures distances at a speed of 0.9 seconds and at a distance of less than 1 foot away up to 3,280 feet! You can even turn off the robotic capabilities of the SX total station and perform reflectorless measurements without a prism.

Laser Pointer and Guide Light

In fact, the Sokkia SX's maximum range maintains the same height accuracy as when using a prism. RED-tech EDM technology uses the same-phase comparison method. Regardless of whether the target is reflectorless, a prism or a reflector sheet, only one laser beam is used for both pointing and measuring. This allows the diameter of the laser beam to change according to the selected measurement mode, ensuring that you achieve superior accuracy. The available green and red laser telescope guide lights provide guidance at a range of nearly 500 feet.

Topcon TSShield Security

This advanced SX-105 comes with the world's first integrated support service, known as the TS shield. It includes a telematic-based communications module that not only sends out a coded signal to disable your surveying instrument if it is lost or stolen, but it also informs you of available software and firmware updates through the cloud. 

Memory and Data Interface

Store up to 500MB of internal memory and up to 8GB of USB flash memory on the Sokkia SX total station. Also included are regular and mini USB 2.0 and RS-232C ports. Even in the toughest of conditions, your data transmission and external power connection are always safe with the dustproof and water-resistant surveying instrument and dust and waterproof single port.

Touchscreen Display and Keypad

The color LCD touch screen allows you to view your data with maximum visibility from any angle using the adjustable contrast, while the graphic icons allow you to check the status of your robotic total station at a glance. Use the alphanumeric keyboard to enter data as symbols, numbers or letters. Each of the 32 keys features a unique concave shape that makes it easy to input data while wearing gloves or using a stylus pen. Both the display and the keyboard are fully illuminated so that you can continue taking measurements, even under dim or dark lighting conditions.

With the trigger key on the side of the total station, you can save time by taking measurements without moving your eye away from the telescope.

The Sokkia SRX's Li-Ion rechargeable batteries that run up to 4 hours on a single charge.  Double the operating time by upgrading to long-life batteries, which allow you to take measurements for up to 7 continuous hours.

Package Options

Your Sokkia Robotic Total Station comes with several accessories designed to help you get full use from your total station: CD-ROM, carrying case and shoulder strap, two rechargeable Li-Ion batteries plus quick recharger with power cable, two styluses, tubular compass, plumb bob, tool kit for instrument adjustments, lens cap and lens hood, vinyl cover, laser caution sign board, wiping cloth, protective film for LCD screen, user manual and quick manual.

Additional Accessories Needed

In order to use your SX-105T total station in robotic mode, a range pole kit is also required. This kit comes with the advanced RC-PR5 remote control unit, a range pole, prism and more; all the tools needed for your robotic surveying job.

These package options can be found in the Essential Accessories section on the right-hand side of the page.

Package options are available to create your own pole system for use with the prism, RC-PR5 remote controller and additional data collector.

The Sokkia SX-105 Robotic Total Station’s unprecedented functionality, with time and money saving single operator remote control system, Red-Tech precise distance measurement, multiple data interfaces, and much more give you a superior product that will catapult your business to the top. Once you discover the freedom of using the Sokkia SRX Robotic Total Station, you'll never go back to using a standard total station again.
