Detailed explanation-1: -The Iridium satellite constellation uses a polar orbit to provide telecommunications services. Near-polar orbiting satellites commonly choose a Sun-synchronous orbit, where each successive orbital pass occurs at the same local time of day.
Detailed explanation-2: -Satellites with polar orbits are used for monitoring the weather, military applications (spying) and taking images of Earth’s surface.
Detailed explanation-3: -Telecommunications satellites are usually placed in geostationary Earth orbit (GEO). GEO is a circular orbit 35 786 kilometres above Earth’s equator and follows the direction of Earth’s rotation.
Detailed explanation-4: -As a satellite in a near-polar sun-synchronous orbit revolves around the Earth, the satellite crosses the equator at approximately the same local sun time every day.
