1. Research Background In recent years, rapid advances in artificial intelligence have driven the widespread adoption of mobile robots, particularly in complex environments where robotic assistance is essential. Autonomous robots are in strong demand for search-and-rescue operations, missions in uninhabited areas, underground and planetary exploration, and service-robot deployment. However, […]

Under ideal conditions, standalone Global Navigation Satellite System (GNSS) technology can deliver positioning results with sufficiently high precision. Nevertheless, it suffers from numerous limitations under special operating conditions and application scenarios. For instance, in complex urban environments, multipath components in observations increase drastically. In more extreme cases, observation dropout may […]
In recent years, visual-inertial odometry has been increasingly adopted by researchers for underwater localization. However, due to the difficulty of obtaining ground truth trajectories in open seas, existing underwater localization datasets often lack complete and high accuracy trajectory references, which limits the application of visual‑inertial odometry in underwater scenarios. To […]
Background Driven by the future demand for precise positioning in applications such as autonomous driving, delivery drones, and the Internet of Things, miniaturized and low-power consumer-grade GNSS chips offer distinct advantages. Typical use cases include rotorcraft platforms subject to strict constraints on the weight and power consumption of GNSS modules […]
The dataset is recorded by SmartToF camera model TC-E2, which acquires depth images with a resolution of 320×240 at a frame rate up to 60 fps. Besides, the TOF camera provides a field of view of 65°×38° in a standard lens. The maximum measurement range is 6 meters. The mechanical […]
RESEARCH BACKGROUND In the last decades, GNSS navigation has been much improved, compared to survey-grade equipment, low-cost devices performance is not satisfied market demands. Many particular scenarios such as offline shopping or open-air parking need high accuracy positioning. Because the raw GNSS data is unavailable, prior researchers can only […]
Abstract: Some students attended the conference of ION GNSS+ 2017 in Portland, America. In this conference, we published three papers which topics are channel modeling, pedestrian navigation and fusion navigation respectively. Full text ION GNSS+ is the world’s largest technical meeting and showcase of GNSS […]
