Characterization of Carrier Phase-Based Positioning in Real-World Jamming Conditions
Remote Sensing, 2021 GNSS signals arriving at receivers at the surface of the Earth are weak and easily susceptible to interference and jamming. In this paper, the impact of jamming on the reference station in carrier phase-based relative baseline solutions is examined ...

Highlights in Science, Engineering and Technology, 2023 Geodesic is a kind of shortest path among all curves in a metric space, which originally appeared in the Gaussian period. Since then, it was extensively applied in various branches of mathematics and physics, such as Riemannian geometry, digital geometry, Einstein’s relativity, etc.
