Constellation walker phase 2

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.
