Technology Integration and Laser Measurement
data transmission and compatibility
inertial navigation system and measurement accuracy
T80 RTK is equipped with the fourth generation super inertial guidance system. The new algorithm framework enables users to complete the initial non-sense calibration during exercise, which is ready to use.
Inertial navigation accuracy status visualization, so that users more clearly understand the measurement status, improve the reliability and accuracy of the measurement.
The measurement method of laser intersection is supported. By measuring the same target point in at least four different directions, the object observation model is constructed, the system error is eliminated, and the measurement accuracy is greatly improved.
application scenarios and efficiency improvement
T80 RTK can perform well in all kinds of scenes, especially in occlusion scenes, such as pipeline positioning under viaduct, etc. When traditional RTK cannot perform lofting normally, T80 RTK can be easily completed through a new laser eye lofting method.
The side camera not only enhances the laser function, but also greatly improves the work efficiency by combining the double camera in the visual direction scene. The lofting path is guided by the front camera at a long distance, and the lofting point is automatically switched to the lower camera at a short distance. The detail 1 rod is in place, and the efficiency is improved by 30%.
price and cost performance
Considering that the T80 RTK integrates a variety of cutting-edge technologies and provides high-precision and high-reliability measurement data, its price is relatively reasonable.
For users who need high-precision positioning, long-distance differential transmission and measurement in complex scenarios, T80 RTK has a high cost performance.
In summary, the COMNAV T80 RTK is the 1 flagship GNSS receiver that integrates multiple cutting-edge technologies with high accuracy and reliability. It performs well in laser measurement, data transmission, inertial navigation system and application scenarios, and has high cost performance and practical value.
