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 a robustly adaptive Kalman filter, the key problem is to construct an adaptive factor to
balance the contributions of the kinematic model information and the measurements on the …

A robust Kalman filter scheme is proposed to resist the influence of the outliers in the
observations. Two kinds of observation error are studied, ie, the outliers in the actual …

Stable and reliable high-precision satellite orbit products are the prerequisites for the
