Acoustic positioning of the seafloor geodetic network is subject to the complex ocean
environment. The measurements are strongly affected by time-varying and location-varying …

In this article, the fast and precise initial alignment of the low-cost rotary strapdown inertial
navigation system under mooring conditions is investigated. The unscented Kalman filter …

In this study, both adaptive and robust one is proposed, considering that the properties of a
classic unscented Kalman filter (UKF) can be degraded severely by the outliers measured in …

With the development of multi-constellation multi-frequency Global Navigation Satellite
Systems (GNSS), more and more observations are available for tightly coupled …

Autonomous underwater vehicle (AUV) acoustic navigation is challenged by unknown
system noise and gross errors in the acoustic observations caused by the complex marine …

Structural health monitoring (SHM) is important in ensuring safety of large civil engineering
structures. Global Navigation Satellite Systems (GNSS)-based technology has been …

In the engineering applications, Kalman filter (KF) is the most commonly used for INS/GPS
integration. This KF-based integration is prone to divergence because of two typical …

From July 11 to 20, 2023, the 28th International Union of Geodesy and Geophysics (IUGG)
general assembly was held in Berlin, Germany. According to the tradition of IUGG, the …

The accuracy of underwater acoustic positioning is greatly influenced by both systematic
error and gross error. Aiming at these problems, the paper proposes a robust zero-difference …

In low-cost micro-electro mechanical system (MEMS)-grade strap-down inertial navigation
system (SINS), failure to compensate inertial sensors errors as well as un-modeled …
