Web11 nov. 2024 · Satellites in low-Earth orbit (LEO) networks can be connected by multi-hop inter-satellite paths. In most LEO network scenarios, the shortest distance path (SDP) is also within the minimum hop path (MHP) set. The distance differences between SDP and various MHPs are less studied. This paper proposes approaches to calculate the SDP and the … Web17 jul. 2015 · Orbital Eccentricity - This is a measure of how far a planet's orbit about the Sun (or the Moon's orbit about the Earth) is from being circular compared to Earth.
