The active satellites in the full Iridium constellation form a Walker Star of 86.4°: 66/6/2, i.e. the phasing repeats every two planes. Walker uses similar notation for stars and deltas, which can be confusing. These sets of circular orbits at constant altitude are sometimes referred to as orbital shells. Orbital shell See more A satellite constellation is a group of artificial satellites working together as a system. Unlike a single satellite, a constellation can provide permanent global or near-global coverage, such that at any time … See more Walker Constellation There are a large number of constellations that may satisfy a particular mission. Usually constellations are designed so that the satellites have similar orbits, eccentricity and inclination so that any perturbations affect … See more In spaceflight, an orbital shell is a set of artificial satellites in circular orbits at a certain fixed altitude. In the design of satellite constellations, an orbital shell usually refers to a collection of circular orbits with the same altitude and, oftentimes, See more Satellite constellations should not be confused with: • satellite clusters, which are groups of satellites moving very close together in almost identical … See more Satellites in medium Earth orbit (MEO) and low Earth orbit (LEO) are often deployed in satellite constellations, because the coverage area provided by a single satellite only covers a small area that moves as the satellite travels at the high angular velocity needed … See more • Satellite internet constellation • Light pollution • Types of geocentric orbit See more Satellite constellation simulation tools: • AVM Dynamics Satellite Constellation Modeler • SaVi Satellite Constellation Visualization • Transfinite Visualyse Professional See more WebIt defines the range of RAAN values for the orbit planes.
