Oblique Plot FSS-IMU614E-P
IMU614E-P inertial module can achieve low cost, high precision and anti-magnetic interference attitude measurement and orientation through data fusion algorithm of IMU and GNSS. Especially in the field of RTK oblique mapping, accurate and consistent oblique position correction can be achieved.
For surveying and mapping poles, it provides ±2.5cm measuring accuracy in the range of_30° inclination Angle, and has the function of correcting installation deviation Angle, which can be adapted to all kinds of centering poles.
