Summary: Attitude determination is crucial in aerospace engineering. This study proposes a new invariant Kalman filter (VBAIKF) by employing variational Bayesian fixed-point iterations to jointly estimate the Lie groups rotation matrix, biased mean, degrees of freedom, and scale covariance matrix of the spacecraft. Simulation results demonstrate the superior filtering adaptability and precision of VBAIKF compared to other methods for attitude determination with biased mean and heavy-tailed process noise.

Summary: This paper evaluates the state estimation performance of processing nonlinear/non-Gaussian systems using the cubature particle filter (CPF), which combines the cubature Kalman filter (CKF) and the particle filter (PF). The CPF algorithm effectively resolves nonlinear/non-Gaussian problems by using the CKF to generate the importance density function. The CPF can achieve a maximum a posteriori probability estimate of the nonlinear system, improving estimation accuracy compared to other particle filter and Kalman filter based approaches.

Summary: Fire safety is crucial for the development of efficient and safe energy systems for space objects. This paper focuses on studying the influence of gravity on combustion processes and analyzes the dynamics of inverted conical methane-air flame under external acoustic excitation. The results show that at high excitation frequencies, the intensity of vortex generation is similar to that observed in experiments with normal gravity, indicating the dominance of acoustic mechanism. Additionally, at an external excitation frequency of 240 Hz, significant growth in shear vortex diameters and increased amplitude of perpendicular oscillations of flame branches were observed, indicating the most intensive large scale instability of flow.
