Q

What is the orbital altitude of INMARSAT Satellites?

🔍 Key Concepts

• Geostationary orbit and what altitude it typically is above the Earth • The relationship between orbital period and distance from Earth (24‑hour orbit) • Typical altitude range of INMARSAT / communication satellites used for global coverage

💭 Think About

• Which of these distances is closest to the well‑known altitude of geostationary communication satellites above the Earth’s surface? • If a satellite must remain fixed over one point on the equator (same rotational period as Earth), does it need to be relatively low, medium, or very high above Earth? • Think about standard values you may have memorized in GMDSS or celestial/nav comms study materials—what number is commonly associated with INMARSAT altitude?

✅ Before You Answer

• Verify the approximate altitude of a geostationary orbit (in miles or kilometers) from your study notes. • Check which of the options is closest to that standard geostationary altitude. • Confirm that INMARSAT satellites used for GMDSS are in geostationary orbit over the equator, not low‑Earth or medium‑Earth orbits.
