This paper provides a tutorial overview of the IRIDIUM(R) low earth orbit (LEO) satellite system. Section I contains an introduction to the IRIDIUM(R) network as well as the system specifications. Section II discusses the satellite constellation design, orbital parameters, and horizontal pointing angles between satellites. Section III introduces the idea of time dependent connectivity in a mobile network, and analyzes the cycle of network connectivity for IRIDIUM(R). Section IV discusses the…

On the Path to 6G: Low Orbit is the New High
An overview of the key aspects of low Earth orbit (LEO) satellite communication networks towards 6G is provided, including the evolution of LEO satellite constellations and capabilities, and the standardization aspects from 5G evolution to 6G are discussed.
A Method of System Timing in TDMA Systems for LEO Satellites
A method of estimating the distance between terminal stations and the satellite is proposed based on the prediction of satellite orbit and the estimating of orbit parameters by kalman filter algorithm and greatly reduces the protection time slot between burst signals and satisfies the requirements of TDMA Systems for LEO Satellites.
Implementation of a geographical routing scheme for low Earth orbiting satellite constellations using intersatellite links
An Iridium‐like constellation and a megaconstellation are investigated and compared regarding the address resolution procedures, the average end‐to‐end transmission delay, and the dropping and rerouting rates.
