Sokkia SX-102T Auto-Tracking Total

Extremely Accurate Auto-Tracking
Incorporating the industry’s most advanced laser and image processing
technologies, the SX offers market leading prism tracking capability
and enhanced prediction of prism movement. The SX accurately locks and
tracks a moving prism In any jobsite environment.

RED-tech Technology Reflectorless EDM

  • Fast distance measurement of 0.9s regardless of object.
  • Reflectorless operation from 30cm to 1,000m.(With Kodak Gray Card
    white side (90% reflective). Brightness level at object surface: ≤500
  • Coaxial EDM beam and laser-pointer provide fast and accurate


Advanced Angle Measurement System

SX features Sokkia’s original absolute encoders that provide long-term
reliability in any job site condition. Dual-axis compensator ensures
stable measurements even when setup on uneven terrain.

Long-range Data Communication

  • The SX series of total stations features Bluetooth® Class1
    wireless technology for reliable data communications.
  • All SX data is instantly available at the Bluetooth-equipped

RC-PR5 Remote Control System
The RC-PR5 On-Demand Remote allows for rapid prism search. A built-in
directional sensor monitors the prism movement so the SX turns left or
right whichever direction is closer.

Advanced Prism Configuration
Advanced six-prism configuration provides unsurpassed measurement
precision. ATP1 fits a range pole; ATP1S sliding prism is designed for
a pin pole.

Waterproof, Rugged, and Operator

  • IP65 dustproof / waterproof rating.
  • Metal chassis and heavy duty handle.
  • Standard usage temperature range -20 to +50°C.


  • Cloud-based Solutions for
    Precise Positioning

    • MAGNET™ is a software family that uses the “cloud” to
      seamlessly connect the field and office for data exchange,
      communications, asset tracking and more. Real-time connections. When
      you need it. Where you need it.
  • MAGNET™ Field
    • Data collection, stakeout, roads, and coordinate geometry.


Every SX total station is equipped with a telematics-based
multifunction communications module providing the ultimate security and
maintenance capabilities for your investment.
If an activated instrument is lost or stolen, you can send a coded
signal to the instrument and disable it – Your total station is secure
anywhere in the world!
And, in the same module, you have daily connectivity to cloud based
Sokkia servers that can inform you of available software updates and
firmware enhancements.
