NDN in large LEO satellite constellations
Proceedings of the 8th ACM Conference on Information-Centric Networking, 2021Large low Earth orbit (LEO) satellite constellations are intended to provide global low-latency high-bandwidth Internet connectivity. Due to their large scale and high mobility nature, networking is a big challenge. In this paper, we investigate applying Named Data Networking (NDN) to this scenario.

SiGe Circuits for Future LEO Constellations
2022 Microwave Mediterranean Symposium (MMS), 2022This work presents an overview of the current state-of-the-art Power Amplifiers and Low-Noise amplifiers in the 40–75 GHz frequency band (i.e., V -band). These RF blocks are critical for the development of future LEO constellations that have recently begun to target these frequencies. Special attention is brought to GaAs, GaN, SiGe, FDSOI and classical

LEO satellite constellation performance analysis
Proceedings of MILCOM '93 - IEEE Military Communications Conference, 2002To date, radio frequency crosslinks have been the preferred communication medium for low Earth orbit (LEO) satellite networks. However, laser crosslinks in satellite constellations introduce many new and interesting research problems not addressed in these conventional methods.

An Efficient LEO Global Navigation Constellation Design Based on Walker Constellation
2020 IEEE Computing, Communications and IoT Applications (ComComAp), 2020Compared with medium Earth orbit (MEO) and high Earth orbit (HEO) satellites, low Earth orbit (LEO) satellites have lower cost, smaller power loss and shorter transmission delay, which mean they can be used in many areas like navigation and space-based internet of things (IOT), etc.

On Dual Connectivity in 6G Leo Constellation
2024 IEEE International Mediterranean Conference on Communications and Networking (MeditCom)Dual connectivity (DC) has garnered significant attention in 5G evolution, allowing for enhancing throughput and reliability by leveraging the channel conditions of two paths. However, when the paths exhibit different delays, such as in terrestrial and non-terrestrial integrated networks with multi-orbit topologies or in networks characterized by ...

Navigation services from LEO constellations
2022Current generation satellite-based navigation systems have been typically located in Middle Earth Orbit (MEO) to achieve a convenient trade-off between number of spacecraft required for coverage and launch costs and signal power issues. The rapid spread of very large constellations in Low Earth Orbit (LEO), with hundreds or more satellites, is changing

Perturbed ISL Analysis in LEO Satellite Constellation
2020 IEEE 3rd International Conference on Electronics and Communication Engineering (ICECE), 2020In the satellite mobile communication systems, there are direct channels among satellites by inter-satellite link (ISL), which could increase the autonomy of the constellation network. The relative position between satellites in the low earth orbit (LEO) constellation is time-varying, and the satellites are not continuously visible.

PCRLB-Based Sensor Management for LEO Constellation
2018 IEEE CSAA Guidance, Navigation and Control Conference (CGNCC), 2018In this paper, we are concerned with the problem of utilizing a LEO infrared constellation in order to track the midcourse ballistic missile. Due to the limited sensor resources of LEO constellation, an appropriate sensor management policy is necessary. A PCRLB-based sensor management approach is used as the basis for sensor management.
