Spoofing attacks have become an increasing threat to global navigation satellite system
receivers. Existing anti-spoofing algorithms concentrate on the detection of these attacks; …

The paper presents a method of estimating parameters in two competitive functional models.
The models considered here are concerned with the same observation set and are based …

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

In order to improve the positioning accuracy of the combined navigation system when GPS
outages, a hybrid model using Grey Wolf Optimizer to fine-tune Gated Recurrent Unit (GWO …

Ionospheric disturbances can be detrimental to accuracy and reliability of GNSS positioning.
We focus on how ionospheric scintillation induces significant degradation to Precise Point …

The onboard adaptive model can achieve the online real-time estimation of performance
parameters that are difficult to measure in a real aero-engine, which is the key to realizing …

When certain constraints in the kinematic state parameters of a multi-sensor navigation
system exist, they should be taken into account for the improvement of the positioning …

A low-cost IMU and odometer integration system is developed in this paper for underground
pipeline mapping. A tightly coupled integration between IMU and odometer is implemented …

The BeiDou system is the first global navigation satellite system in which all satellites
transmit triple-frequency signals that can provide the positioning, navigation, and timing …

GNSS/INS integrated navigation system is particularly outstanding in providing reliable
navigation information for land vehicle applications. However, GNSS measurements are …
