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.

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

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.

A Study of Constellation for LEO Satellite Network
22nd AIAA International Communications Satellite Systems Conference & Exhibit 2004 (ICSSC), 2004For a LEO constellation system, it is important to optimize the orbit parameters to maximize the quality of communication service. At the Next-generation LEO System (NeLS) Research Center, the LEO parameters were evaluated for a mobile satellite communication system. A 2π constellation was selected to maintain a stable inter-satellite link (ISL).

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.

Computing call-blocking probabilities in leo satellite constellations
IEEE Transactions on Vehicular Technology, 2003We present an analytical model for computing call-blocking probabilities in a low Earth orbit (LEO) satellite network that carries voice calls. Both satellite-fixed and Earth-fixed constellations with interorbit links and handoffs are considered. We assume a single beam per satellite.
