Sokkia SRX Robotic Total Station

Sokkia SRX5 5” Robotic Total Station with Long-Range Bluetooth Communication. The unique SRX On-Demand Remote Control System revolutionizes the way you survey with total stations. Intelligent target search and robust Auto-Tracking capability minimize downtime due to loss of target lcok or an undesired sighting of reflective objects. Unique prism systems can be optimally configured to obtain the highest work efficiency.


  • Long-Range Bluetooth Link between total station and pole (300m - 980ft)- No more troublesome radios to configure.
  • RED-tech EX High Precision Reflectorless EDM- Pinpoint accuracy on measurements up to 500m (1,640ft)
  • Fully Functional Auto-Tracking
  • False Sighting Recovery- remote control system quickly returns it to prism if SRX gets caught sighting another reflective object
  • Guide Light for rough lateral positioning

The SX-Series from Sokkia is a fully-robotic, auto-tracking and auto-pointing robotic total station, with on-demand target reacquisition. The SX-Series features innovative auto-tracking and EDM technologies that maximize the robotic capability.

Sokkia’s auto-tracking SX features cutting-edge laser technology, optimized optical design, a newly-developed motor drive mechanism, and further refined tracking algorithm, to achieve extremely robust auto-tracking capability. The SRX X-Series constantly tracks a moving prism even in strong backlight or with repetitive interruptions in the line-of-sight, dramatically reducing the possibility of losing a prism lock. Even if the lock is lost, the advanced on-demand remote control system allows the SRX to instantly recover the prism lock, ensuring increased productivity in all robotic surveying and setting-out tasks.

Sokkia’s SX has Bluetooth wireless technology for cable-free use, making this single-operator Total Station even more convenient. Multiple data interfaces, including USB and Compact Flash, make data in the field easy to transport back to the office. Saving data is easier than ever before with the options of USB or compact flash.

To set this robot apart from all others, the Sokkia SX offers 1,000m (3,280 ft.) reflectorless measurement range. The new RED-tech 800 EDM provides increased accuracy and range in distance measurements with or without reflectors, incorporating the new optical design, the enhanced signal processing algorithm, as well as the ultra-high signal modulation frequencies of up to 468.75MHz. It measures up to 6,000m (19,680 ft.) distance with a single prism, and up to 800m (2,620 ft.) without a reflector. Sokkia’s developers didn’t stop there; they also enhanced the encoder with IACS technology. Groundbreaking new Independent Angle Calibration System (IACS) provides extremely reliable angle measurement with unprecedented stability.

Revolutionary Remote Control Concept

The unique SRX On-Demand Remote Control System revolutionizes the way you survey with total stations. It eliminates the drawbacks of previous systems which were often stressful and time-consuming

  • Minimize downtime during target search and lock
  • Instant recovery from accidental sighting of undesired reflective objects
  • No more worrying about line-of-sight even while tracking the target.

On-Demand Remote Control System: The On-Demand Remote Control System is comprised of the prism-side RC-Controller and an RC-Detector in the SRX handle. The RC-Controller emits a laser fan beam that is detected by the RC-Detector. SRX quickly rotates in the direction of the prism, auto-points and starts measurement right away

SDR Data Collection Software: SDR is a versatile data collection software package for prism-side SRX control. SDR provides full suppor t for all total station measurements and calculations from as-built surveys to setting-out

Fast Search and Lock: Simply press the key on prism-side data collector. The intelligent RC-Controller commands SRX to rotate in the shor test direction and the SRX quickly detects the search beam from the RC-Controller for a smooth prism lock

Focus on Where You're Going: With SRX, you can smoothly continue measurement even if buildings, trees or passing traffic interrupt the line of sight. Even the roughest terrain poses no problem for SRX. All you need to do is pay attention to your footing and SRX will take care of the rest. If prism lock should be lost, press the measurement key and the RC-Controller automatically calls the SRX, allowing you to recover the target lock without missing a beat

False Sighting Recovery: If SRX gets caught sighting another reflective object, the on-demand remote control system quickly calls it back to the prism. Recovery and measurement are done at the push of a button

Dramatically Improve Setting-Out Efficiency

  • SRX in combination with the On-Demand Remote Control system dramatically improves setting-out efficiency
  • Using SRX Auto-Tracking, direction and distances are graphically and numerically displayed on the prism-side data collector for real-time point navigation.
  • Speed up operation using the Guide Light for rough lateral positioning. Setting-out efficiency can also be improved using the SRX Auto-Pointing function
