Inter-satellite Routing Study for LEO Constellations Based on Orbit Prediction
2023 26th ACIS International Winter Conference on Software Engineering, Artificial Intelligence, Networking and Parallel/Distributed Computing (SNPD-Winter), 2023 Due to the periodic motion of the LEO constellation network, finding the shortest delay path between two satellites in a dynamic network is a challenge for LEO constellations to perform inter-satellite communication.

Inter-Plane Inter-Satellite Connectivity in LEO Constellations: Beam Switching vs. Beam Steering [PDF]
Global Communications Conference, 2021 Low Earth orbit (LEO) satellite constellations rely on inter-satellite links (ISLs) to provide global connectivity. However, one significant challenge is to establish and maintain inter-plane ISLs, which support communication between different orbital ...

GNSS RTK Positioning Augmented with Large LEO Constellation
Remote Sensing, 2019 It is widely known that in real-time kinematic (RTK) solution, the convergence and ambiguity-fixed speeds are critical requirements to achieve centimeter-level positioning, especially in medium-to-long baselines.

LEO Satellite Constellation for Internet of Things
IEEE Access, 2017 Internet of Things (IoT) is one of the evolutionary directions of the Internet. This paper focuses on the low earth orbit (LEO) satellite constellation-based IoT services for their irreplaceable functions. In many cases, IoT devices are distributed in remote areas (e.g., desert, ocean, and forest) in some special applications, they are placed in some ...
