For autonomous navigation, localization in an environment is a fundamental capability. In this regard, it is necessary for robots to have environmental maps. The environmental maps are, in general, built...
The ubiquitous planes and structural consistency are the most apparent features of indoor multi-story Buildings compared with outdoor environments. In this paper, we propose a tightly coupled LiDAR-Inertial 3D SLAM...
Pseudolites system is a good solution to the problem of navigation in indoor environments because of its great flexibility, strong signal power and high accuracy. In pseudolites system, the Time-Hopping...
Developers targeting Android platforms can obtain raw GNSS measurements, which can achieve submeter or even decimeter-level positioning accuracy. An accurate receiver measurement error model is an important prerequisite for precise...
Technique PPP–RTK combines the advantages of both the Precise Point Positioning (PPP) and the Real-Time Kinematic (RTK) positioning. With the emergence of multi-frequency Global Navigation Satellite System (GNSS) observations, it...

As the necessity of location information closely related to everyday life has increased, the use of global navigation satellite systems (GNSS) has gradually increased in populated urban areas. Contrary to...
This paper proposes a high-precision positioning method using graph-based optimization with only a global navigation satellite system (GNSS) in an urban environment with GNSS multipath signals. GNSS has become an...
This paper describes the first-place solution at a Google smartphone decimeter challenge (GSDC), which was held from May to August 2021. The GSDC is a competition for positioning accuracy using...
