Which of the following is a feature of the Iridium Satellite Systems?

The Iridium Satellite System is known for its constellation of sixty-six Low Earth Orbit (LEO) satellites. This unique configuration allows for comprehensive global coverage, providing voice and data communication services to users on the ground, in the air, and at sea. The deployment of sixty-six satellites ensures that there are always sufficient satellites available to facilitate communication, even in remote areas where traditional communication infrastructures may not exist.

LEO satellites, like those in the Iridium network, orbit at lower altitudes compared to other satellite systems, resulting in reduced latency and improved transmission quality for users. The deployment of this specific number of satellites supports the system's capability to offer reliable service by maintaining adequate satellite visibility for users.

In contrast, other options either refer to different orbital classifications or satellite quantities that do not align with the structure of the Iridium system. Understanding the specific characteristics of satellite constellations is essential for recognizing how they function and serve communication needs effectively.
