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

Helicopter Test of a Strapdown Airborne Gravimetry System
Airborne gravimetry from a helicopter has been a feasible tool since the 1990s, with gravimeters mounted on a gyro-stabilised platform. In contrast to fixed-wing aircrafts, the helicopter allows for a higher spatial resolution, since it can move slower ...

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.

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 ...

Improved Pedestrian Location Method for the Indoor Environment Based on MIMU and sEMG Sensors
In order to guarantee the pedestrian location accuracy for the indoor environment, an improved pedestrian location method based on the improved Mahony complementary filter algorithm is proposed by the data fusion of microinertial measurement unit (MIMU) and sEMG sensors, which are installed on the lower limbs.
