During the first iteration, the orientation estimate, q−, is initialized by ecompass with an assumption that the x-axis points north. Estimate Gravity from Orientation The gravity vector is interpreted as the third column of the quaternion, q−, in rotation matrix form: g[1×3]=(rPrior...

Importantly, the rms (i.e., the accuracy) of SF-PPP solution is improved from 6.3 m to 1.7 m and 1.6 m by integrating the smartphone and Xsens IMU, respectively. The IMU provides little gain for 95th percentile error as the tightly-coupled PPP/IMU solutions depend heavily on GNSS in ...
Vehicle motion model updates can be used to enhance the navigation system observability [41], especially when there are significant vehicle dynamics (e.g., accelerating or turning). Sensors such as the mass flow and Hall-effect sensors can measure the forward velocity. Meanwhile, it is assumed ...
The hub has been rotated to a fixed known yaw ψh and ψh is measured by a compass, where the wave- and wind-induced motions have a negligible influence on ψh. 2. The variation in rotation of the IMU about the x- and y-axes caused by the monopile motion is negligible, i.e.,...
If you can’t move the body in this position, then move your device – instead of a head mounted screen , consider a hand-held LCD screen that is hold in horizontal position and tilted to control the plane. This might kill some thrill of the project , i.e. the sensation of flying,...
(IMU) which uses triaxial gyroscope, accelerometer, and compass sensors in con- junction with advanced sensor fusion processing and on-board quaternion-based ori- entation filtering algorithms to determine orientation relative to an absolute reference in PostureMonitor: Real-Time IMU Wearable Technology...
