Application of Adaptive Weighted Strong Tracking Unscented Kalman Filter in Non-Cooperative Maneuvering Target Tracking

open access: yesAerospace, 2022
An adaptive weighted strong tracking unscented Kalman filter is proposed in this paper for long-range relative navigation alongside non-cooperative maneuvering targets. First, an equation for obtaining the relative motion of two bodies is derived, it can

Relative navigation technique with constrained GNSS data for formation‐flying CubeSat mission, CANYVAL‐C

open access: yesNavigation, 2021
This study introduces and verifies a relative navigation technique for two Cube-Sats in formation flying as part of the CANYVAL-C mission. Because the mission requires precision and robustness subject to restricted computational complexity, the technique
