Sokkia’s market-proven precision Gyro Station now incorporates auto-pointing capability and automates the observation of the pendulum gyro oscillation (precession) by newly equipped image sensor. It automatically finds true north in 19 minutes* and determines the azimuth with 15" precision regardless of the work site environment. Operation is speedy and easy even for unskilled operators to reduce stress and fatigue.
*When measured at 35° latitude area. Measurement time differs by the latitude due to the nature of gyro motor.
Acquire true north anytime and anywhere
GYRO X uses a suspended gyromotor that oscillates around the earth's meridian (true north) due to the principle of precession caused by the rotation of the earth. This principle realizes faster and more precise measurement than other solutions.

Only 19 minutes* for measurement
Gyro X requires only 19 minutes for measurement, effectively doubling your work efficiency,* and decreasing operators' stress anytime and anywhere, on every job.
*Combination of follow-up measurement and time measurement. When measured at 35° latitude area. Measurement time differs by the latitude due to the nature of gyro motor.
15" Azimuth Accuracy
The combination of special application software and advanced motor drive system allows the true north position to be automatically calculated in accuracy of 15" (5mgon / 0.074mil).
Eliminates the chance of human error
Freedom from human error is another advantage of Gyro X. It eliminates reticle reading error or timing measurement error. With Gyro X, even unpracticed operators can produce consistent accurate results.
Easy operation even for unskilled operators
Only three steps are required for measurement.
1. Point the Gyro Station in the general direction of true north.
2. Release the clamp
3. Push measurement button
Auto-pointing total stations
Gyro Station incorporates a gyroscope unit on auto-pointing total stations. These total stations implement the gyro calculation programs as well as work as surveying instruments to enhance efficiency and productivity on all survey projects after the measurement of true north.
