Pain points in the use of traditional RTK measuring instruments
Traditional RTK measuring instruments require a long time to align and calibrate the level during use to ensure that the measuring arm is perpendicular to the ground. After a complex preparation process, once the position is moved, or the measuring rod is leveled or tilted, recalibration is necessary, which is very inconvenient.
When measuring some obstructed or inconvenient locations, such as corners, the RTK signal below the obstruction may be obstructed, resulting in inaccurate testing and even inability to carry out the test normally.
The role of inertial sensors/IMUs in RTK measuring instruments_Integrating IMU in RTK measuring instruments allows for real_time interference free and automatic tilt compensation without the need for complex calibration processes, rotation, leveling, or other initialization steps. Simply walk a few meters to initialize the internal IMU module and enable RTK measurement in challenging on_site environments. Automatic pole tilt compensation can increase measurement and layout speed by up to 30%.
Surveying and mapping personnel can measure at a large tilt angle, improving the convenience of work. In some corners or locations where measurement is not convenient, measurement work can also be easily completed.
The IMU in inertial RTK is mainly used to compensate for the tilt angle of the RTK receiver during tilt measurement, thereby achieving tilt measurement without the need for alignment. Forsense provides the standard IMU614E and the IMU614E_P with built_in tilt measurement algorithm. Forsense's tilt measurement algorithm and IMU performance ensure the accuracy and stability of equipment during tilt measurement, enabling easy initialization during walking, making work more efficient. At the same time, it also supports the initialization method of standard front and rear joysticks.
