A fusion of inertial navigation system and global positioning system (GPS) has been
proposed to implement a robust navigation system for a transporter. In several cases, the …

This article presents a novel time synchronization attack (TSA) model for the Global
Positioning System (GPS) based on clock data behavior changes in a higher-order …

Knowledge of the global navigation satellite system (GNSS) satellite clock error is crucial in
real-time precise point positioning (PPP), seismology, and many other high-rate GNSS …

The precise point positioning (PPP) technique has been widely used for remote time and
frequency transfer. With the development of the multiple global navigation satellite system …

Robust positioning and navigation of a mobile robot in an urban environment is
implemented by fusing the Global Positioning System (GPS) and Inertial Navigation System …

Interference events, both intentional and unintentional, are significant threats to global
navigation satellite system (GNSS) service continuity. In the presence of interference, it can …

Oscillators and clocks are affected by physical mechanisms causing amplitude fluctuations,
phase noise, and frequency instabilities. The physical properties of the elements composing …

This paper considers the problem of tracking a mobile receiver using signals of Low Earth
Orbit (LEO) satellites. Based on Time-Difference of Arrival (TDOA) and Frequency-Difference …

In this paper, we develop a dynamic model of receiver clock phase noise to enable
Interactive Multiple Model (IMM) filters to maintain GPS carrier phase lock through …

This paper proposes a robust positioning algorithm using a modified fault detection and
isolation (FDI) algorithm and the horizontal dilution of precision (HDOP) for localising a yard …
