DTN LEO satellite communications through ground stations and GEO relays [ C ]//Proc of the 5th Interna- tional ICST Conference. 2013:1-12.F. Apollonio, C. Caini, M. Lulf, "DTN LEO Satellite Communications through Ground Stations and GEO Relays", in Proc. of PSATS 2013, Toulouse, ...
The ground stations (GS) deployment has the key impact on the system throughput for LEO satellite constellation network. However, the GS deployment planning is challenging due to the spatial and temporal distribution of traffic demands and the time-varying topology of the LEO satellites. To solve ...
Ground stations can communicate with LEO (Low Earth Orbiting) satellites only when the satellite is in their visibility region. The ground station's ideal horizon plane is in fact the visibility region under 0of elevation angle. Because of natural barriers or too high buildings in urban areas, ...
Some governments see ground stations and local frequency allocation as a revenue opportunity, in the same way that some countries have heavily taxed the main internet infrastructure operating in their territory. However, satellite-to-satellite laser communications can help to minimize the effects of ...
Established satellite ground stations can communicate with LEO satellites only when the satellite is in their visibility region. Each ground station is characterized by its own ideal horizon plane. Because of natural barriers that plane is modified to the designed one, defined by minimal elevation, ...
stations. They are powered by solar energy and continue to function as long as they remain undamaged and have a power supply. It’s important to note that the operational efficiency of a satellite greatly depends on its altitude and the orbit it resides in – LEO, MEO, or GEO. Each of...
Practical horizon plane and communication duration for Low Earth Orbiting (LEO) satellite ground stations The duration of the visibility and so the communication duration varies for each satellite pass at the ground station, specifically for LEO satellites which...

Their low orbit allows LEOs to communicate with ground-based equipment with a low latency of just 2–27 milliseconds – a time lag comparable or even superior to some land-based connections.How do LEO satellites work? LEO satellite networks communicate with land-based IoT devices either directly...
This article introduces key market trends driving low Earth orbit (LEO) satellite deployments. It will discuss the basic operation of a LEO satellite system and present some of the semiconductor RFIC advances, which are enabling the next generation of Ku and Ka band LEO ...
