Product Introduction
The GTYD8-JT Gyro-Theodolite integrates gyroscopic and theodolite technologies for high-precision directional measurement in challenging environments. Utilizing the gyroscopic principles of rigidity and precession, along with Earth s rotation, it rapidly determines true north within 75° latitude, unaffected by terrain, magnetic fields, or daylight. Key functions include azimuth measurement, engineering layout, and directional error control in mining, tunneling, and underground construction. Its optimized optical and mechanical design ensures user-friendly operation and robust performance. 1429
Technical Specifications
Equipped with a high-speed gyro motor (21,500 RPM) and precision optics (7.5x magnification), the GTYD8-JT delivers accurate results (azimuth error ≤±15"). The built-in inverter supplies 400Hz three-phase AC power, while a 3Ah battery supports field operations. With a 35-second swing period and 1.5-minute braking time, it balances efficiency and stability. Compatibility with laser rangefinders enables polar coordinate mapping for expanded applications. 12629
Applications
Ideal for underground mining orientation and tunnel alignment, this instrument minimizes directional errors in surveying. Its rapid north-seeking capability is valuable for academic research and large-scale installations. Portable and durable, it suits long-term projects in diverse environments, ensuring reliable directional benchmarks. 21417
