Physical Layer Authentication for LEO Satellite Constellations

open access: yes2022 IEEE Wireless Communications and Networking Conference (WCNC), 2022
Physical layer authentication (PLA) is the process of claiming identity of a node based on its physical layer characteristics such as channel fading or hardware imperfections. In this work, we propose a novel PLA method for the inter-satellite communication links (ISLs) of the LEO satellites.

Extended Geometry and Probability Model for GNSS+ Constellation Performance Evaluation

open access: yesRemote Sensing, 2020
We proposed an extended geometry and probability model (EGAPM) to analyze the performance of various kinds of (Global Navigation Satellite System) GNSS+ constellation design scenarios in terms of satellite visibility and dilution of precision (DOP) et al.

LEO-Based Satellite Constellation for Moving Target Detection [PDF]

open access: yesRemote Sensing, 2022
With the rapid development of cooperative detection technology, target fusion detection with regard of LEO satellites can be realized by means of their diverse observation configurations. However, the existing constant false alarm ratio (CFAR) detection research rarely involves the space-based target fusion detection theory.

Impacts of Orbital and Constellation Parameters on the Number and Spatiotemporal Coverage of LEO-LEO Occultation Events

open access: yesRemote Sensing, 2021
The development of small-satellite technologies allows the low Earth orbit intersatellite link (LEO-LEO) occultation method to observe the Earth’s atmosphere with global coverage and acceptable costs using electromagnetic signals, in which the L/X/K/M ...

Network Pruning for Extending Satellite Service Life in LEO Satellite Constellations [PDF]

open access: yes2015 IEEE International Conference on Data Science and Data Intensive Systems, 2015
We address the problem of network pruning for extending the service life of satellites in LEO constellations. Satellites in LEO constellations can spend over 30 % of their time under the earth's umbra, time during which they are powered by batteries.
