In an embedded system with limited processing resources, as the number of tasks grows, they interfere with each other through preemption and blocking while waiting for shared resources such as CPU time and memory. The main task of an Any-Time Kalman Filter (AKF) is real-time state estimation from measurements using available processing resources. Due to limited computational resources, the AKF may...
Focusing on nonlinear/non-Gaussian filters and based on analysis of the sampling-importance-resampling algorithm, this paper examines principles and application of particle filter (PF) in satellite orbit determination. There may be large error of initial estimation and non-Gaussian distribution of state and measurement in satellite orbit determination. To solve the two problems, an improved PF algorithm...
