New Generation SRX Robotic Total Stations

Sokkia Corporation has released four new SRX total stations, SRX1X, SRX2X, SRX3X and SRX5X. The new SRX series is primarily focusing on auto-tracking and distance measurement capabilities. The auto-tracking system includes new motors and driving mechanism, new optics and laser system. The refined tracking algorithm enhances the ability to predict the future prism positions, enabling more stable tracking and faster prism reacquisition.
According to Brice Walker, vice-president of survey sales , in field tests, the new SRX has proved its extremely robust prism tracking capability works in any job site environment even with intensive reflections from behind a prism, or with repetitive interruptions in the line-of-sight. "The instrument's new telescope is optimised for both of the prism tracking and distance measurements while maintaining the industry's highest 2.5 seconds resolving power.

The new RED-tech 800 EDM provides increased measurement range of 800m (2,620ft.) without a reflector, and up to 1,000m (3,280ft.) under specific conditions. Measurement accuracy is increased to 1.5mm + 2ppm when using Sokkia's 360° prism or standard prism. Reflectorless measurement accuracy is enhanced to 2mm + 2ppm.

Walker said, "The new RED-tech 800 employs ultra-high modulation frequencies of up to 468.75MHz for measurement signals, which is 2.5 times higher than the previous RED-tech EX. This extremely short signal wavelength, combined with enhanced digital processing technology, has increased both the measurement range and precision."

The new SRX is equipped with the enlarged 3.7-inch LCD touch-screen display. Using a built-in light sensor, the LCD brightness is automatically adjusted to the optimum level.

Four models are available with different angle accuracy grades: SRX1X (1"), SRX2X (2"), SRX3X (3") and SRX5X (5").
