GPS Satellites Orbit the Earth in Which Type of Orbit?

Do you know in which type of orbit GPS satellites mainly operate?

✅ Answer: Medium Earth Orbit (MEO).

The Global Positioning System (GPS) constellation consists of satellites that orbit the Earth in Medium Earth Orbit (MEO) at an altitude of approximately 20,200 km. This orbit provides broad global coverage and enables accurate positioning, navigation, and timing services worldwide.

📘 What You Will Learn

✔ Which orbit GPS satellites use
✔ Why MEO is suitable for navigation satellites
✔ Different types of Earth orbits
✔ Important facts for UPSC, SSC & Banking Exams

📌 Key Facts

✔ Correct Answer: Medium Earth Orbit (MEO)
✔ Altitude: Approximately 20,200 km above Earth
✔ Orbital Period: About 12 hours
✔ Primary Purpose:

Global navigation
Positioning
Precise timing
🌍 Why Do GPS Satellites Use MEO?

✔ Provides wide global coverage
✔ Requires fewer satellites than Low Earth Orbit (LEO) for worldwide service
✔ Offers stable and continuous navigation signals
✔ Ensures accurate positioning and timing across the globe

🎯 Static GK

Types of Earth Orbits:

✔ Low Earth Orbit (LEO): Approximately 160–2,000 km
• Used for Earth observation, remote sensing, and many communication satellites.

✔ Medium Earth Orbit (MEO): Approximately 2,000–35,786 km
• Used mainly by navigation satellite systems such as GPS, GLONASS, Galileo, and NavIC (some NavIC satellites also use geosynchronous orbits).

✔ Geostationary Orbit (GEO): 35,786 km above the equator
• Used for weather, television broadcasting, and communication satellites.

🎯 Exam Tip

📝 Remember:

GPS → MEO (Medium Earth Orbit) → ~20,200 km

🎯 Useful For

• UPSC
• SSC CGL, CHSL, CPO, MTS
• Banking Exams (IBPS, SBI, RBI)
• Railways
• NDA & CDS
• State PCS Exams
• General Knowledge Preparation
