Navigation/positioning systems have become critical to many applications, such as
autonomous driving, Internet of Things (IoT), Unmanned Aerial Vehicle (UAV), and smart …

Research on the key anti-spoofing technologies is of great significance to resist the
increasingly complex threat of spoofing attacks on global navigation satellite system (GNSS) …

To navigate in global navigation satellite systems (GNSS) signal-challenged environment,
for example, foliage canopy, urban canyon, indoor, etc., high-sensitivity GNSS receivers are …

Abstract All Global Navigation Satellite System (GNSS) signals could be easily disturbed by
intentional jamming in hostile environment. To deal with these threats, ultra-tight GNSS/INS …

Urban navigation using GPS and fish-eye camera suffers from multipath effects in GPS
measurements and data association errors in pixel intensities across image frames. We …

Direct Position Estimation (DPE) has been introduced as a robust global navigation satellite
system (GNSS) positioning method. Its superior performance stems from the full coupling of …

This paper analyzes the impact that architectural features have on the performance of
deeply integrated and tightly coupled algorithms. The effects of two specific architectural …

This paper proposes a robust vector tracking loop structure based on potential bias analysis.
The influence of four kinds of biases on the existing two implementations of Vector Tracking …

In urban environments, when GNSS signals are weakened, blocked, and interfered with by
multipath, the tracking accuracy and continuity of scalar delay-locked loops (SDLL) …

With the development of Micro‐Electro‐Mechanical‐System (MEMS) technology, size and
accuracy of Chip Scale Atomic Clock (CSAC) gradually improve, and a commercial CSAC …
