Neural Network-Based Attitude Estimation
2020Have an accurate information about the system state is a big challenge in several applications, such as guidance, navigation and control of drones, aircrafts and autonomous robots. INS (Inertial Navigation System) can provide information about attitude of vehicle on which is attached.

Rotation Vector in Attitude Estimation
Journal of Guidance, Control, and Dynamics, 2003An alternative derivation of the spacecraft attitude determination filter is developed to avoid questions of quater-nion normalization or attitude matrix orthogonality constraints, quaternion covariance, and subterfuges used to circumvent these problems. This derivation is based on the Bortz equation for the rotation vector. Because the rotation vector

New quaternion attitude estimation method
Journal of Guidance, Control, and Dynamics, 1994(5) The assumed orthogonality of A and properties of the trace give \\A -B\\ 2 = tr[(A -B)(A -B)T] = 3-2 tr(ABT) + \\B\\ (6)

Estimating Risk Attitudes in Denmark [PDF]
We estimate individual risk attitudes using controlled experiments in the field in Denmark. These risk preferences are elicited by means of field experiments involving real monetary rewards. The experiments were carried out across Denmark using a representative sample of 253 people between 19 and 75 years of age.

ATTITUDE ESTIMATION USING LIGHT CURVES
Tracking and characterizing the space debris population in Earth orbit is necessary to ensure that space can continue to be used safely. However, because space objects are affected by non-conservative forces like drag and solar radiation pressure, predicting the long-term evolution of their orbits is impossible without knowledge of their attitude ...openaire +1 more source
