摘要
惯导技术是第二代GNSS-RTK倾斜改正测量定位的新技术。本文分析了惯导新技术应用于不同倾斜角度及相同停滞时间下GNSS-RTK倾斜测量误差,进而基于实验方案探讨了基于惯导技术的GNSS-RTK倾斜改正可信度,并进而讨论了对中杆在倾斜角30°内惯导传感器对平面点位改正精度及倾斜角在50°内高程改正精度都是可靠的,超越这个角度值,其精度会随倾角增大而下降,且改正误差大小与倾斜不同方向无关。
Inertial navigation technology is a new technology of GNSS-RTK tilt correction measurement and positioning(Ⅱ).Based on the experiment,the thesis analyzes tilt measurement error when inertial navigation technology is used in different angles and at the same stagnation time.It discussed the reliability of tilt correction in inertial navigation technology.It also explains the centering rod’s accuracy of plane point correction of inertial navigation sensors in the angle of 30 degrees and elevation correction accuracy in the angle of 50 degrees are reliable.Beyond that,with the increase of angle,the precision will decrease.The inclined spinning has no effect on error correction size.
