Why did Iridium cancel its constellation?

In the end, however, all but Iridium scaled back or canceled their intended constellations because of high costs and limited demand. All suffered financial problems. After that experience, many industry analysts and investors remain skeptical about the viability of large LEO constellations. The recent failures of LeoSat and OneWeb reinforce that impression.

How do satellites track?

Traditionally, satellites have been accessed and tracked via parabolic-dish antennas. This equipment is poorly suited to LEO constellations, which will have numerous satellites all rapidly crossing a ground receiver’s field of view at the same time. Antennas with electronically scanned apertures (ESAs), also called electronically steerable antennas, can shift beams (and track and access large numbers of satellites) without physical movement. ESAs can also be designed for modular assembly, which could allow manufacturers to produce large numbers of basic parts for use in both constellation ground stations and consumer equipment, thereby improving economies of scale. Other important advances in ground equipment include new predictive analytics and network-optimization techniques that use available ground-entry points more effectively.

How far away are satellites from Earth?

Although costly, they are highly capable and have long service lives. Their altitude—more than 35,000 kilometers from Earth—provides them with a wide field of view, allowing operators to cover most of the planet’s surface with three satellites spaced at appropriate intervals. Recent technological advances, including new high-throughput and reconfigurable designs, have improved both efficiency and performance.

How many satellites are orbiting the Earth?

More than 2,500 active satellites now orbit the Earth, and amateur astronomers and other observers are seeing more every month. 1#N#1. UCS Satellite Database, Union of Concerned Scientists, December 16, 2019, We supplemented this information with data about launches through March 2020.#N#Historically, satellite communication involved geosynchronous (GEO) spacecraft—large systems that have become increasingly capable over the years. But now nongeosynchronous-orbit (NGSO) communications constellations, including low-Earth-orbit (LEO) and medium-Earth-orbit (MEO) satellites, are taking to the skies, and their number could soon soar. If current satellite internet proposals become reality, about 50,000 active satellites will orbit overhead within ten years. Even if the most ambitious plans do not come to pass, the satellites will be manufactured and launched on an unprecedented scale.
