Multiframe Target Localization With Strapdown Seeker Based on Self‐Adaptive L‐SHADE
Strapdown seekers are increasingly used in the terminal guidance for the advantages of small size and low cost. However, due to the coupling of the seeker with the missile and its limited field of view, there is a risk of losing the target. This paper proposes a multiframe fusion target localization method for missiles with strapdown seekers, which can

Application of covariance analysis method in design of modulated inertial navigation systems
Error analysis of inertial navigation systems is one of the important tasks in inertial navigation research. Through error analysis, the contribution of each error in the system to the total error can be obtained.

In this work, SmokeNav, a system that fuses inertial sensor and millimeter‐wave radar for accurate user localization and metric map reconstruction in visually degraded environments, is presented. Using a foot‐mounted inertial sensor with human motion constraints, SmokeNav leverages inertial positioning to construct occupancy maps from radar data.

An Aided Navigation Method Based on Strapdown Gravity Gradiometer
The gravity gradient is the second derivative of gravity potential. A gravity gradiometer can measure the small change of gravity at two points, which contains more abundant navigation and positioning information than gravity.

The proposed algorithm VBRAUKF is useful for dynamic alignment of SINS/DVL. According to the inaccurate modelling of the observation model, an adaptive estimation strategy for the measurement noise covariance is designed by Variational Bayesian algorithm based on unscented Kalman filter algorithm to solve dynamic attitude alignment for SINS/DVL ...
