Geostationary Satellites: Stars That Never Move

追加: 2026-05-05

[00:00:00]Imagine you're gazing at the night sky and a star stays perfectly still while everything else wheels by. That's no star. It's a geostationary satellite locked in perfect sync with Earth's rotation. These marvels orbit our planet once every day, matching the 24-hour spin exactly. From the ground, they appear frozen in place, hovering over the equator. No need to track them with a dish antenna. Just point and lock on for crystal clear TV, internet, or weather data. But how high must they fly to achieve this? Precisely 36,000 km above Earth's surface, far beyond the International Space Station, out where gravity's pull perfectly balances their speed. At that altitude, these silent sentinels beam signals worldwide, powering our connected age.
