Leica MSS400 Series Sensors & SP Technology

  • Ensuring speed, performance, precision and productivity (SP), the MSS400 Series Sensors incorporate SP Technology that allows faster digging without loss of precision at higher speeds, dramatically increasing machine utilisation and productivity.

    Excavators can now take on even more fine grading jobs, allowing contractors to complete their work with fewer machines and helping them to finish their projects ahead of schedule and under budget.

    As part of the MSS400 series, the MSS420 sensors for underwater dredging jobs are built on the well-established MSS400 Series Sensor technology. Designed to be used down to 40 m at 5 bar pressures, the MSS420 sensors are equipped with reinforced components such as pressure tight connectors, a robust sensor housing, rugged cabling and stainless-steel brackets making it the most reliable equipment for underwater applications. The Leica MSS420 dredging sensors can be programmed to boom 1, boom 2, stick, bucket and even tilt sensors.

    High precision attainable at any speed

    Inertial measurement units (IMUs) combined with gyroscopes and accelerometers offers the most responsive sensor technology on the market to improve digging accuracy and increase the operator’s overall speed in completing the work. SP Technology significantly enhances GNSS performance, reduces the need for rework and increases uptime during poor GNSS coverage or temporary loss of correction signals.

    The MSS400 Series Sensors allow the operator to work faster while maintaining advanced accuracy at higher speeds on challenging job sites where productivity is essential.

    Improved sensor technology

    SP Technology offers better dynamic update performance of angles, allowing the machine to move faster while keeping guidance values on the operator's panel accurate. Precise angle calculation makes the excavator more accurate and efficient.

    No learning curve, no reconfiguration

    All excavators equipped with iCON excavate and GNSS can be easily updated to get the full benefit of this incredible SP Technology. Complexity is removed compared to a regular guidance system with regards to installation and operator usage.


    • Increase your excavator's speed, performance, precision and productivity
    • Increase in uptime due to a 20 per cent decrease in installation time and 30 per cent decrease in calibration tim
    • Protect your jobsite from over digging due to SP Technology
    • Visualise the movement of the machine in real-time on the display, drastically reducing operator error
    • Eliminate “dead spots” with 360-degree range of motion accurate reading
    • Increase your field of applications by adding underwater applications to your portfolio
