Contact Plan Design for Cross-Linked GNSSs: An ILP Approach for Extended Applications
Huan Yan, Juan A. Fraire, Ziqi Yang +10
Global Navigation Satellite Systems (GNSS) employ inter-satellite links (ISLs) to reduce dependency on ground stations, enabling precise ranging and communication across satellites…
Weighted Nonlocal Total Variation in Image Processing
Haohan Li, Zuoqiang Shi, Xiaoping Wang
In this paper, a novel weighted nonlocal total variation (WNTV) method is proposed. Compared to the classical nonlocal total variation methods, our method modifies the energy funct…
Autonomous Orbit Determination Analysis of a Conceptual Cislunar Navigation Constellation based on Inter-Satellite Range Measurement
Haohan Li, Yuxuan Miao, Xiyun Hou +5
With the community's increasing interest in the cislunar space, building a navigation constellation servicing the whole cislunar space has become a pressing need. Previous studies…
An efficient iterative thresholding method for image segmentation
Dong Wang, Haohan Li, Xiaoyu Wei +1
We proposed an efficient iterative thresholding method for multi-phase image segmentation. The algorithm is based on minimizing piecewise constant Mumford-Shah functional in which…
A new solar radiation pressure model for some orbit types in the cislunar space
Haohan Li, Yuxuan Miao, Xiyun Hou +4
For satellites in the cislunar space, solar radiation pressure (SRP) is the third largest perturbation, which is only less significant than the lunisolar gravity perturbations. It…
Joint Contact Planning for Navigation and Communication in GNSS-Libration Point Systems
Huan Yan, Juan A. Fraire, Ziqi Yang +11
Deploying satellites at Earth-Moon Libration Points (LPs) addresses the inherent deep-space coverage gaps of low-altitude GNSS constellations. Integrating LP satellites with GNSS i…
