In this study, we use measurements from over 4,735 globally distributed Global Navigation
Satellite System receivers to track the progression of traveling ionospheric disturbances …

Different from differential code biases, the observable-specific code biases (OSBs) directly
describe the biases of individual pseudorange measurements, which provide full flexibilities …

We present here the Empirical Canadian High Arctic Ionospheric Model (E‐CHAIM) quiet N
m F 2, perturbation N m F 2, and quiet hm F 2 models. These models provide peak …

Global navigation satellite systems (GNSS) allow estimating total electron content (TEC).
However, it is still a problem to calculate absolute ionosphere parameters from GNSS data …

The paper aims to review recent advances regarding the observational and monitoring
capabilities of the ionization conditions in the Earth's upper atmosphere. The analysis spans …

The differential code bias (DCB) of global navigation satellite systems (GNSSs) affects
precise ionospheric modeling and applications. In this paper, daily DCBs of the BeiDou …

The short-term variability in receiver code biases (RCBs) has been identified as a prominent
source of error leading to the degradation of precise point positioning (PPP) performance …

Abstract The Assimilative Canadian High Arctic Ionospheric Model (A‐CHAIM) is an
operational ionospheric data assimilation model that provides a 3D representation of the …

The long baseline (LBL) underwater navigation paradigm relies on the conversion of travel
times into pseudoranges to trilaterate position. For real-time autonomous underwater vehicle …

As one of the important factors influencing the ionospheric total electron content (TEC)
estimation accuracy, receiver differential code biases (DCBs) should be properly removed …
