About ideal relative motions of rigid heavy body [PDF]
INCAS Bulletin, 2017 Consider an origin which is fixed at the Earth’s surface, and a rectangular celestial coordinates axes with this origin. The gravity acceleration is the approximate sum of the centrifugal acceleration of the origin relatively to the Earth’s center and ...

Gravitomagnetic Field and Time-Dependent Spin-Rotation Coupling [PDF]
, 2003 The Kerr metric of spherically symmetric gravitational field is analyzed through the coordinate transformation from the rotating frame to fixing frame, and consequently that the inertial force field (with the exception of the centrifugal force field) in ...

Beam modeling in a floating frame of reference for torsion dynamics of helicopter rotor blades
Multibody system dynamicsIn the ongoing development of DLR’s Versatile Aeromechanics Simulation Tool, an elastic-beam model is integrated into the multibody system based on the floating frame-of-reference formulation.

Application of Space-Based Orientation Observation in Orbit Determination of BeiDou Satellites
AerospaceWhen a navigation constellation depends exclusively on inter-satellite links for autonomous orbit determination, the absence of inertial frame orientation measurements can result in the accumulation of rotational errors across the entire constellation ...

External Velocity Aided Coarse Attitude and Position Alignment for Dynamic SINS
IEEE Access, 2018 This paper concerns about the dynamic alignment for the strapdown inertial navigation system (SINS), especially in the case of no GPS assistance. A novel coarse alignment algorithm using external reference velocity in b-frame is proposed.

Speed Measurement in an Accomoving Reference System
East European Journal of Physics, 2020 A method of direct measurement of the observer's velocity (peculiar velocity) relative to the accompanying reference system is proposed and investigated. To measure peculiar velocity, it is proposed to use the measurement of stellar light aberration.

Computation of fluid flows in non-inertial contracting, expanding, and rotating reference frames [PDF]
Journal of Computational Physics, 2007 We present the method for computation of fluid flows that are characterized by the large degree of expansion/contraction and in which the fluid velocity is dominated by the bulk component associated with the expansion/contraction and/or rotation of the flow.

Neural Network-Based Intuitive Physics for Non-Inertial Reference Frames
IEEE Access, 2021 Classical mechanics offers us reliable means to predict various physical quantities, but it is difficult to derive the precise dynamic equations underlying most phenomena and obtain physical quantities in real-world situations.
